  • [Title] Endometriosis of the Vermiform Appendix Presenting as a Tumor.
  • : Endometriosis of the vermiform appendix is a rare condition.
  • Most patients with this disease are asymptomatic or present as acute or chronic appendicitis.
  • The author herein reports a case of appendiceal endometriosis presenting as a tumor at the appendiceal oriffice.
  • A colon endoscopy showed a tumor in the appendiceal orifice.
  • Two biopsies of the tumor showed no remarkable changes.
  • Imaging modalities including CT and MRI also revealed an appendiceal tumor.
  • Resection of appendix, cecum, ascending colon, terminal ileum, and 16 lymph nodes were performed under the clinical diagnosis of gastrointestinal stromal tumor.
  • Grossly, a tumor measuring 3 x 3 x 3 cm was recognized in the appendiceral orifice.
  • Histologically, the tumor was endometriosis consisting of islands of endometrial glands and stroma.
  • The present case suggests that appendiceal endometriosis may present as a tumor.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Childhood carcinoid tumors: description of a case series in a Brazilian cancer center.
  • CONTEXT AND OBJECTIVE: Carcinoid tumors are very rare both in children and adults.
  • About 85% of these tumors develop in the gastrointestinal tract.
  • The objective of the present study was to describe our experience with children treated of carcinoid tumors, and investigate the frequency morphological findings and results.
  • DESIGN AND SETTING: Report on case series, at the Department of Pediatrics of Centro de Tratamento e Pesquisa Hospital do Câncer, São Paulo.
  • METHODS: This was a retrospective analysis of clinical pathological data and outcomes among children (< 18 years old) with carcinoid tumors admitted from January 1, 1990, to December 31, 2001.
  • In eight cases (89%), the primary tumor site was the appendix and in one (11%) it was the left bronchus.
  • For those with primary tumor in the appendix, the main complaint was abdominal pain, which led to appendectomy.
  • Only one patient underwent right hemicolectomy due to tumor extension into the serosa.
  • The patient with bronchial tumor underwent left pneumonectomy.
  • All patients had localized disease and are alive and free of disease.
  • CONCLUSION: Although the majority of carcinoid tumors arise from the appendix, these tumors can also occur in other primary sites.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Carcinoid tumour of the appendix in children: a case report.
  • Carcinoids are the most common tumours of the appendix.
  • The clinical presentation of the appendiceal carcinoids is similar to that of acute appendicitis, although in many cases the tumour is diagnosed incidentally during an operation.
  • The diagnosis should be confirmed histologically.
  • The prognosis in patients with local disease is excellent.
  • We report a case of a carcinoid tumour in the tip of the appendix of a thirteen year old girl which was diagnosed intraoperatively.
  • Ten years after the operation there is no evidence of recurrence or metastases, and the patient is considered free of disease.

5. O'Donnell ME, Badger SA, Beattie GC, Carson J, Garstin WI: Malignant neoplasms of the appendix. Int J Colorectal Dis; 2007 Oct;22(10):1239-48

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Malignant neoplasms of the appendix.
  • BACKGROUND: Appendiceal neoplasms, first described in 1882, are still rare, with pre-operative diagnosis invariably difficult.
  • MATERIALS AND METHODS: A retrospective histopathological review of all appendicectomy specimens was completed between April 1994 and December 2003 to identify patients diagnosed with malignant neoplasms.
  • A literature search of the PubMed database was then performed using the medical search headings; appendix, tumour, neoplasm and malignancy.
  • Other appendiceal pathologies were identified after appendicectomies, hemicolectomy and oophorectomy.
  • CONCLUSIONS: From our own experience and a subsequent review of the literature, we recommend right hemicolectomy as the treatment of choice for all malignant appendiceal neoplasms, except for small CCT less than 2 cm in diameter at the tip of the appendix, with a low proliferative index, without angiolymphatic or mesoappendiceal extension.

MedlinePlus Health Information. consumer health - Carcinoid Tumors.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Carcinoid tumor of the appendix in childhood: the experience of two Italian institutions.
  • OBJECTIVES: Although rare, carcinoid tumor of the appendix is the most common neoplasm of the gastrointestinal tract in children and adolescents.
  • It is usually an incidental finding after a laparotomy for appendectomy, with a frequency of 2 to 5 cases per 1000 appendectomies.
  • The experience with 14 cases of carcinoid reported in the appendix is described.
  • METHODS AND RESULTS: In six patients the tumor measured 1 cm or less; only in one patient did it measure 2 cm.
  • In three patients the tumor measured between 1 and 2 cm and in four the size was not known.
  • All tumors were discovered by chance, and three patients underwent further surgery as a result of suspected involvement of the margins.
  • All the patients were alive with no evidence of disease at 24 to 214 months from diagnosis.
  • In our experience, both patients with local invasiveness and the patient with a tumor larger than 2 cm had good outcomes.
  • Ileocolectomy performed in the patient with a 2-cm tumor and in another two patients with smaller tumors did not demonstrate residual disease.
  • Although the need for right hemicolectomy still remains controversial for tumors measuring more than 2 cm, the approach may be nonaggressive in case of tumors invading the serosa and the periappendiceal fat.
  • Nonaggressive treatment has been suggested by some authors in cases of tumors larger than 2 cm; however, larger series need to be evaluated.

7. Tang LH: Epithelial neoplasms of the appendix. Arch Pathol Lab Med; 2010 Nov;134(11):1612-20
COS Scholar Universe. author profiles.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Epithelial neoplasms of the appendix.
  • CONTEXT: The appendix gives rise to an array of epithelial neoplasms showing glandular or neuroendocrine differentiation, and some tumors with elements of both cell types.
  • Although some appendiceal neoplasms resemble their counterparts in the small and large intestines (conventional adenocarcinoma and carcinoid tumor), the appendix also gives rise to relatively unique entities including mucinous neoplasms and goblet cell carcinoid tumors, which present a challenge in pathologic classification and clinical management.
  • OBJECTIVE: To review clinical and diagnostic issues for 3 pathologic types of epithelial neoplasms of the appendix:.
  • (1) adenocarcinoma, with specific focus on mucinous neoplasm;.
  • (2) goblet cell carcinoid tumor and associated adenocarcinoma; and (3) typical carcinoid tumor.
  • CONCLUSIONS: The most important issue in pathologic assessment of epithelial tumors of the appendix is to understand the clinical implications inherent in the diagnosis.

8. Pahlavan PS, Kanthan R: Goblet cell carcinoid of the appendix. World J Surg Oncol; 2005 Jun 20;3:36

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Goblet cell carcinoid of the appendix.
  • BACKGROUND: Goblet cell carcinoid (GCC) of the appendix is a rare neoplasm that share histological features of both adenocarcinoma and carcinoid tumor.
  • The clinical presentations of this neoplasm are also varied.
  • This review summarizes the published literature on GCC of the appendix.
  • The focus is on its diagnosis, histopathological aspects, clinical manifestations, and management.
  • METHODS: Published studies in the English language between 1966 to 2004 were identified through Medline keyword search utilizing terms "goblet cell carcinoid," "adenocarcinoid", "mucinous carcinoid" and "crypt cell carcinoma" of the appendix.
  • RESULTS: Based on the review of 57 published papers encompassing nearly 600 diagnosed patients, the mean age of presentation for GCC of the appendix was 58.89 years with equal representation in both males and females.
  • Accurate diagnosis of this neoplasm requires astute observations within an acutely inflamed appendix as this neoplasm has a prominent pattern of submucosal growth and usually lacks the formation of a well-defined tumor mass.
  • Concomitant distant metastasis at diagnosis was present in 11.16% of patients with the ovaries being the most common site in 3.60% followed by disseminated abdominal carcinomatosis in 1.03%.
  • Local lymph node involvement was seen in 8.76% of patients at the time of diagnosis.
  • GCC's of the appendix remains a neoplasm of unpredictable biological behavior and thus warrants lifelong surveillance for recurrence of the disease upon diagnosis and successful surgical extirpation.
  • CONCLUSION: GCC of the appendix is a rare neoplasm.
  • Due to its wide range of presentation, this tumor should be considered as a possible diagnosis in many varied situations leading to abdominal surgery.
  • The advocated plan of management recommended for patients with tumors that involve the adjacent caecum or with high-grade tumors with histological features such as an increased mitotic rate involve initial appendectomy with completion right hemicolectomy due to the high possibility of local recurrence with intraperitoneal seeding prior to lymph node involvement and a 20% risk of metastatic behavior.
  • In female patients with GCC of the appendix regardless of age, bilateral salpingo-oophorectomy is advocated.
  • In cases with obvious spread of the disease chemotherapy, mostly with 5-FU and leucovorin is advised.

  • [Title] Are we missing diagnostic opportunities in cases of carcinoid tumours of the appendix?
  • OBJECTIVE: Carcinoid tumour of appendix is an uncommon condition that can potentially give rise to a variation in management.
  • We aimed to assess the occurrence and mode of presentation of carcinoid tumour of appendix, and any variation of its management.
  • The mean age of patients with carcinoid tumour (41.8 years) was significantly higher than those with non-carcinoid pathology (27.7 years) (p = 0.001).
  • The incidence of female patients was higher than the male amongst the carcinoid tumour group (female/male ratio 2.2).
  • Eight patients as well as their general practitioners (53.3%) were unaware of the diagnosis.
  • CONCLUSIONS: Carcinoid tumour of the appendix remains an incidental diagnosis.
  • There was a wide variation in involving the multidisciplinary team, conveying the diagnosis to patients as well as their general practitioners, and follow-ups.

  • [Title] A rare case of coexistence of carcinoid tumor of appendix vermicularis and ileal endometriosis.
  • BACKGROUND: Carcinoid tumor is the most common tumor of appendix with overall good prognosis.
  • CASE REPORT: We here report the coexistence of carcinoid tumor of appendix and ileal endometriosis in a 37-year-old nulliparous woman who came to the emergency room with right lower abdominal pain mimicking acute appendicitis.
  • With preoperative suspicion of acute appendicitis, laparatomy was performed and revealed apparently normal looking appendix, along with a nodule in the terminal ileum.
  • Both the appendix and ileal nodule were removed.
  • Histological examinations revealed carcinoid tumor of appendix and ileal endometriosis.
  • CONCLUSION: Many cases of carcinoid tumor of the appendix and ileal endometriosis are diagnosed incidentally.

  • CASE: Our case is the second reported case of mature cystic teratoma involving the appendix, and, to our knowledge, it is the first reported in a female who had two simultaneous teratomas, one arising from the appendix and one arising from the right ovary.
  • CONCLUSION: Although mature cystic teratoma is a rare tumor of the appendix, it should be considered in the differential diagnosis of appendiceal masses.
  • The differential diagnosis of appendiceal masses, including clinical and pathologic features, is discussed in detail.

  • [Title] Immunohistochemical expressions of cytokeratins, mucin core proteins, p53, and neuroendocrine cell markers in epithelial neoplasm of appendix.
  • Epithelial neoplasms of appendix are infrequent, and their pathological features are not fully characterized.
  • We collected 33 cases of appendiceal tumors and examined immunohistochemically the expression of cytokeratins (CK, CK7, and CK20), mucin core protein (MUC1, MUC2, MUC5AC, and MUC6), E-cadherin, chromogranin A, and p53 protein.
  • Clinically, mucinous tumors were predominant in females.
  • Immunohistochemically, all the tumors expressed CK20, whereas CK7 was positive in one third of the cases.
  • Similarly, MUC2 was expressed in all the tumors, whereas MUC1 and MUC5AC were detected in about a half of the cases.
  • Although chromogranin A-positive cells are generally sparse in normal appendix, they were more common in mucinous tumors than in nonmucinous tumors.
  • Contrary to the previous data reported (Mod Pathol 2002;15:599-605), mucinous carcinoma exhibited a higher frequency of p53-positive cells (mean 29%) compared with mucinous adenoma (2.8%) (P < .001), whereas nonmucinous tumors showed high levels of p53-positive cells to similar extent (51%-67%) in both adenoma and carcinoma.
  • The high expression of p53 protein coincided with the presence of mutations in multiple sites of TP53 gene in mucinous tumors.
  • This is the first report that characterized the immunophenotypic profile of appendiceal epithelial neoplasms with an emphasis of a higher frequency of p53 positivity in mucinous carcinoma cases compared with mucinous adenoma in the appendix.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Diverticular disease of the vermiform appendix: a diagnostic clue to underlying appendiceal neoplasm.
  • Acquired diverticula of the vermiform appendix are rare and arise as a result of different pathogenetic mechanisms.
  • One of the etiologies includes proximally located, often unsuspected small neoplasms.
  • Although the association of appendiceal diverticulosis and neoplasia is known, it remains underemphasized in the teaching and practice of surgical pathology.
  • To investigate the frequency of appendiceal neoplasms with acquired diverticulosis, we conducted a retrospective analysis of all appendectomy specimens received in our institution for a 55-month period (January 2002-July 2006).
  • Eleven (48%) appendectomy specimens with diverticulosis also harbored an appendiceal neoplasm.
  • The association of appendiceal neoplasms with diverticulosis was statistically significant (P < .0001, 2-sided Fisher exact test).
  • Neoplastic processes included 5 well-differentiated neuroendocrine tumors (carcinoids), 3 mucinous adenomas, 1 tubular adenoma, and 2 adenocarcinomas.
  • We stress the need for meticulous gross assessment with histologic examination of the entire appendectomy specimen in cases of appendiceal diverticulosis.
  • Thorough examination is required to rule out an underlying neoplasm as a cause of diverticulosis.
  • As acquired diverticula represent a rare finding, examination of the entire appendix in this setting does not create a significant impact on the workload within the pathologic laboratory.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Lipid-rich and clear cell neuroendocrine tumors ("carcinoids") of the appendix: potential confusion with goblet cell carcinoid.
  • The so-called clear cell change has been described in neuroendocrine tumors at several locations.
  • Those associated with von Hippel Lindau disease are pathognomonically "clear" and the cytoplasmic appearance has been ascribed to intracytoplasmic lipid.
  • However, lipid has not been demonstrated in all cases of clear cell carcinoid tumors.
  • Such variants have not been described in carcinoid tumors of the appendix and cases with a prominent proportion of clear or more correctly, lipid-rich cytoplasm may bear a superficial resemblance to goblet cell carcinoid and/or signet ring adenocarcinoma.
  • Seven cases, in 5 females and 2 males ranging in age from 22 to 65 years, were noted to have a population of lipid-rich and vacuolated clear cells accounting for 25% or more of the tumor population.
  • The carcinoid tumors were incidental in all cases with 4 of patients presenting with appendicitis, 2 with concomitant mucinous cystadenocarcinomas of the appendix and 1 with an adenocarcinoma of the ascending colon.
  • Morphologically, the tumors had a nested and trabecular pattern and were composed of an admixture of microvesicular and clear lipid-rich cells.
  • None of the patients have shown evidence of recurrent disease.
  • The importance of recognizing this variant of carcinoid tumor in the appendix is to avoid confusion with goblet cell carcinoid tumors with or without a signet ring adenocarcinoma.
  • The presence of multi-vacuolated, foamy and clear cells, some resembling signet ring or goblet cells, in otherwise classic carcinoid tumors is rare but should be considered in this context in the appendix.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Combined classical carcinoid and goblet cell carcinoid tumor: a new morphologic variant of carcinoid tumor of the appendix.
  • Carcinoid tumors are the most common neoplasms of the appendix.
  • Goblet cell carcinoid has been regarded as a distinctive tumor type, not related to classic carcinoids, and to our knowledge combinations of these 2 tumor types have not been described in detail.
  • In this report, we describe 5 cases of combined classical carcinoid and goblet cell carcinoid (GCC) tumors of the appendix.
  • Four men and 1 woman, (mean age 53.4 y) presented with acute appendicitis (4 cases), whereas 1 presented with a pelvic mass owing to widespread pelvic disseminated disease.
  • The tumors (0.6 to 6.0 cm) were located in the mid-portion and the tip of the appendix.
  • Four patients are alive and asymptomatic, whereas the patient with disseminated pelvic disease died 6 months after surgery.
  • All 5 appendiceal tumors had microscopic features of both classical carcinoid and GCC, either intimately admixed or separate but closely apposed.
  • The extent of the 2 components varied, with classical carcinoid representing 60% to 90% of the tumor.
  • In view of the fact that these combined carcinoid tumors appear to behave more as goblet cell carcinoids, detailed microscopic examination of classical carcinoid tumors of the appendix is suggested and larger series with longer follow-up is required to ascertain the true biologic potential of this unique form of combined carcinoid tumor of the appendix.
  • The occurrence of both carcinoid types in the same appendices suggests a closer histogenetic relationship than previously believed, although the possibility that the 2 components represent separate, independent primaries ("collision tumors") can also be considered.

  • Diverticulosis of the appendix is a relatively rare pathological finding.
  • Appendiceal diverticulosis is usually an incidental finding and clinically asymptomatic.
  • Appendiceal diverticulitis is a distinct entity with several clinical and pathological differences from acute appendicitis.
  • Therefore, appendiceal diverticulitis should be considered in the clinical differential diagnosis, especially in adult males with chronic abdominal pain.
  • Appendiceal diverticulosis demonstrates a significant association with obstructing or incidental appendiceal neoplasms.
  • It may play an important role in the development of pseudomyxoma peritonei, which is associated with appendiceal mucinous tumors.
  • When discovered either by preoperative radiological investigations or during an exploratory operation, prophylactic appendicectomy is advocated to prevent the risk of complications and to rule out the possibility of a coexisting neoplasm.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Neuroendocrine tumours (carcinoids) of the appendix.
  • Neuroendocrine tumours (NETs) of the appendix (formerly 'carcinoids') are rare and are usually detected incidentally after appendectomy.
  • They are preferentially located at the tip of the appendix.

  • [Title] Laparoscopy-assisted ileocecal resection for mucosa-associated lymphoid tissue lymphoma of the appendix: case report.
  • A 74-year-old female had repeated relapses of right lower abdominal pain; a colonoscopic examination showed a submucosal tumor of the appendix.
  • Under provisional diagnosis of appendicitis caused by a submucosal tumor, a laparoscopic operation was performed.
  • The laparoscopic observation did not reveal the typical finding of appendicitis.
  • The tumor was thought to be a malignant neoplasm.
  • The ileocecal region was excised with lymph node dissection.
  • Macroscopically, the mass was localized in the appendix and did not infiltrate to the cecum.
  • Immunohistochemically, the tumor cells were positive for CD20 and CD79a and negative for CD3, CD10, and cyclin D1.
  • The histological diagnosis was mucosa-associated lymphoid tissue (MALT) lymphoma of the appendix.
  • Furthermore, very few cases of the appendiceal MALT lymphoma have been reported.
  • The laparoscopy was used in the case of a patient diagnosed with appendicitis and considered the possibility of MALT lymphoma of the appendix.
  • We then performed an ileocecal resection, which is considered radical surgery.
  • The present case suggests that a laparoscopic observation is helpful for the appropriate diagnosis and therapy of MALT lymphoma of the appendix.

  • OBJECTIVE: To summarize the experience in the diagnosis and surgical treatment of carcinoid tumors of the appendix.
  • METHODS: From 1972 to 2006, 64 patients with carcinoid tumors of the appendix received surgical treatment in our hospitals.
  • The operation modes were determined according to the doctor's judgments based on the age of the patients, the nature, size, location, infiltration depth and lymph node metastasis of the tumors.
  • CONCLUSION: Carcinoid tumor of the appendix is rare with a high rate of misdiagnosis before operation.
  • Surgical resection is the only effective treatment for this disease and proper operation mode is the key to achieve good survival.

  • BACKGROUND: The aim of this study is to evaluate the clinical and histopathological features and the treatment of carcinoid tumors of the appendix.
  • METHODS: A retrospective review of medical records and pathology specimens of patients with carcinoid tumor of the appendix has been done.
  • RESULTS: The histopathological examination of the appendices revealed carcinoid tumor in 11 out of 6777 (0.16%) patients operated for acute appendicitis.
  • The tumor was localized in the distal 1/3 region in 10 patients and in the proximal 1/3 region in 1 patient.
  • The mean tumor diameter was 0.73+/-0.36 cm (0.3-1.5).
  • Ten patients had classical type carcinoid tumor whereas goblet cell carcinoid tumor was only seen in one patient.
  • CONCLUSION: In tumors with a diameter of 1 to 2 cm, appendectomy is the treatment of choice.
  • No recurrence was detected with tumors smaller than 2 cm with simple appendectomy.

  • [Title] A comprehensive study of nondysplastic and dysplastic serrated polyps of the vermiform appendix.
  • Although similar lesions occur in the appendix, they have never been systematically investigated.
  • We evaluated a study group of 56 serrated polyps, a control group of 17 mucinous cystadenomas, and 4 adenocarcinomas with adjacent serrated polyps of the appendix to better understand their pathogenesis.
  • We conclude that molecular features of the "serrated neoplastic pathway" are present with similar frequencies among dysplastic and nondysplastic serrated appendiceal polyps and are not highly prevalent in adjacent carcinomas.
  • These features, including BRAF mutations, may be more closely related to a serrated morphology in appendiceal polyps rather than biologically important changes.

  • A tumor was found by colonoscopic examination at the orifice of vermiform and was diagnosed pathologically as goblet cell carcinoid of the appendix.
  • We performed intraperitoneal paclitaxel(PTX)administration at 70 mg/m(2) week without any resection of the tumor.
  • For about one year, her tumor was controlled but became worse thirteen months after diagnosis and died.

  • Burkitt's lymphoma is a high grade B-cell neoplasm.
  • This rapidly growing tumour may cause symptoms due to mass effect or direct involvement of the bowel.
  • Clinical presentations like acute abdomen can be secondary to intestinal obstruction, intussusception or sometimes perforation.We describe here a case of an adult male with an unusual presentation of appendiceal Burkitt's lymphoma mimicking acute cholecystitis or appendicitis.

  • The purpose of this study was to explore CK19 and CD99 immunostaining in mucin-producing neuroendocrine (goblet cell) and classical carcinoids of the appendix.
  • CK19/CD99 immunoexpression did not correlate with extent of tumor invasion and mesoappendiceal extension, mitotic activity, Ki-67 labeling index, presence of extracellular mucinous pools dissecting muscle, and angiolymphatic and perineural/neural invasion.
  • There is no difference in the immunostaining for CK19 and CD99 between GCCs and classic carcinoids, and both types of neuroendocrine tumor show the same extent of expression of both markers.

  • Polish recommendations regarding management of patients suffering from neuroendocrine tumors of small intestine and appendix are presented.
  • Small intestine, especially ileum represent most common origin of these tumors.
  • Symptoms are atypical, diagnosis could be often accidental.
  • Chromogranin A is useful in the laboratory diagnostics, and urinary excretion of 5-hydroxyindoloacetic acid is helpful for the diagnostics and monitoring of the disease.
  • The treatment of choice in the neuroendocrine tumors of small intestine and appendix is radical or palliative surgery, if possible using endoscopy.
  • The crucial in biotherapy is somatostatin analogs application, possible in symptomatic treatment of hormonally functioning tumors.
  • Chemotherapy is less successful in disseminated or locally advanced intestinal neuroendocrine tumors, so radioisotope therapy should be considered in each case of unresectable tumor.

  • Primary adenocarcinoma of the appendix is a rare malignancy that constitutes less than 0.5% of all gastrointestinal neoplasms.
  • Usually the diagnosis is made only after histological examination of surgically removed inflamed appendix.
  • Alternatively represent an unexpected finding, confirmed by frozen section, during surgery performed for acute appendicitis or other non appendiceal pathologies.
  • Natural history is strongly influenced by anatomic peculiarities of the appendix that predispose to early spread and perforation.
  • The correct management is the right hemicolectomy as a primary procedure in the case of preoperatively or intraoperatively diagnosis or as secondary procedure, after two-three weeks from appendectomy, when the microscopic examination of specimen reveals the presence of adenocarcinoma.
  • Right hemicolectomy is the best treatment for all histologic types (colonic, mucinous, adenocarcinoid), in presence of perforation and even in Dukes A tumors.
  • The Authors report a case of primary adenocarcinoma of the appendix occurred in a 78 year-old female patient, diagnosed incidentally during surgery performed for ileus from suspected cecal neoplasm.

  • [Title] Modern systemic chemotherapy in surgically unresectable neoplasms of appendiceal origin: a single-institution experience.
  • BACKGROUND: Appendiceal neoplasms include tumors ranging from benign-appearing cells with widespread mucin deposits to aggressive poorly differentiated signet ring cell adenocarcinomas.
  • Traditionally, these tumors are treated with cytoreductive surgery followed by hyperthermic intraperitoneal chemotherapy.
  • A retrospective analysis was conducted to determine the benefit of modern systemic chemotherapy in patients with disseminated appendiceal neoplasm who were not considered optimal candidates for cytoreductive surgery.
  • Anderson Cancer Center tumor registry between January 2000 and July 2005.
  • RESULTS: Of 186 patients diagnosed with appendiceal neoplasm, 54 (29%) patients considered to be suboptimal surgical candidates received > or =2 cycles of systemic chemotherapy.
  • Thirty (55.6%) patients had a disease control rate noted as a complete response, partial response, or stable disease.
  • CONCLUSIONS: Systemic chemotherapy has a role in appendiceal neoplasm patients who are suboptimal candidates for cytoreductive surgery.
  • The intermediate PFS indicates the challenges that exist for appendiceal neoplasm patients in this setting.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Incidental carcinoid tumors of the appendix: do they affect presentation or prognosis?
  • Carcinoid tumors are the most common neoplasm of the vermiform appendix, with most found incidentally after surgery for appendicitis.
  • To determine in patients presenting with appendicitis if incidental carcinoid tumors affected presentation or prognosis, we reviewed our experience.
  • Of 1350 patients receiving an appendectomy from 1992 to 2000 for appendicitis, 20 were found to have appendiceal carcinoid tumors.
  • Comparing tumor patients to 251 consecutive patients whom underwent appendectomy without tumors, we found patients with tumors were older at presentation (41 +/- 4 versus 30 +/- 1 years, P = 0.005) and had initial lower white blood cell (WBC) counts (10.8 +/- 0.8 vs. 14.2 +/- 0.3, P = 0.007).
  • Therefore, these data suggest that patients with carcinoid tumors are older and have lower WBC counts at presentation with appendicitis, although outcome was not affected by their presence.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Laparoscopic right hemicolectomy for mucocele due to a low-grade appendiceal mucinous neoplasm.
  • Tumors of the appendix are rare entities causing mucoceles.
  • Laparoscopic surgery for appendiceal tumors is still controversial, as inadvertent rupture of the lesion due to improper handling will cause pseudomyxoma peritonei.
  • The patient was incidentally discovered to have an appendiceal tumor and referred to us for laparoscopy.
  • Because the tumor involved the entire appendix, a laparoscopic right hemicolectomy was performed without directly handling the tumor.
  • Pathological diagnosis was low-grade appendiceal mucinous neoplasm.
  • The safety of laparoscopic appendectomy for the management of incidentally discovered appendiceal tumors has not yet been established.
  • The main concerns to be addressed are the adequacy of resection and intraperitoneal rupture of the tumor.
  • A formal right hemicolectomy was performed because the tumor involved the entire appendix.
  • We now think laparoscopic surgery for appendiceal tumors is safe, feasible, and even may be beneficial.

  • [Title] Goblet cell carcinoid tumors (adenocarcinoid) of the appendix.
  • PURPOSE: Goblet cell appendiceal carcinoids represent rare tumors that exhibit histologic features of both adenocarcinomas and neuroendocrine tumors.
  • We present the long-term results of a series of 15 patients, focusing on clinical manifestations, diagnosis, and management.
  • Final diagnosis was confirmed by histology.
  • Three patients had metastases at previous diagnosis.
  • Ki67 index was greater than 20 percent in all of them, while in only one with local tumor.
  • Combination chemotherapy with either cisplatin plus etoposide or with 5-fluorouracil, cisplatin, and streptozotocin was administered to all patients with metastases resulting in temporary stabilization of disease.
  • Twelve patients are alive, while three died of their disease 9, 13, and 14 months after diagnosis.
  • CONCLUSIONS: The diagnostic value of chromogranin-A, urinary 5-hydroxy-indol-acetic acid, and (111)Indium-labeled octreotide scintigraphy seems to be limited in these tumors.
  • Ki67 index appears to predict tumor behavior.
  • Chemotherapy may have efficacy in metastatic disease, however, more data are required to determine this and the optimal regimen.

  • [Title] Mucinous appendiceal neoplasms: preoperative MR staging and classification compared with surgical and histopathologic findings.
  • OBJECTIVE: The objective of our study was to determine the accuracy of MRI in the preoperative staging and classification of mucinous appendiceal neoplasms and to describe the MRI features that are useful for selecting patients for surgical resection.
  • Two observers reviewed the images for peritoneal tumor at 13 sites, tumor size and distribution, and degree of tumor enhancement.
  • Peritoneal tumor sites were recorded at surgery.
  • Surgical specimens were classified as disseminated peritoneal adenomucinosis tumors, intermediate-grade tumors, or peritoneal mucinous carcinomatosis tumors.
  • RESULTS: Surgery confirmed 232 tumor sites.
  • MRI findings predicting suboptimal cytoreduction included a large (> 5 cm) mesenteric mass, which was present in 75% of the patients in the suboptimal cytoreduction group and 0% of those in the complete cytoreduction group; diffuse mesenteric tumor (88% and 0%, respectively); tumor encasement of mesenteric vessels (88% and 0%); or diffuse small-bowel serosal tumor (75% and 0%).
  • Histopathology results showed six disseminated peritoneal adenomucinosis tumors, four intermediate tumors, and 11 peritoneal mucinous carcinomatosis tumors.
  • Qualitatively, the 11 peritoneal mucinous carcinomatosis tumors showed greater enhancement than the liver, whereas six disseminated peritoneal adenomucinosis and the four intermediate tumors showed less enhancement than the liver.
  • Quantitatively, the mean tumor-to-liver contrast for disseminated peritoneal adenomucinosis and intermediate tumors was 0.67 compared with 1.53 for peritoneal mucinous carcinomatosis tumors (p < 0.0001).
  • CONCLUSION: Of the MR techniques evaluated, delayed gadolinium-enhanced MRI was the most accurate for the staging and classification of mucinous appendiceal neoplasms and provided prognostic information useful for patient selection.

  • Appendiceal tumors exhibiting both neuroendocrine and glandular differentiation are uncommon and have caused difficulty in pathologic classification, prediction of prognosis, and clinical management.
  • In this study, we undertook a retrospective investigation of 63 such cases and classified them as typical GCC (group A) and adenocarcinoma ex GCC on the basis of the histologic features of the tumor at the primary site.
  • The clinical characteristics and prognosis were compared within these groups and with conventional de novo appendiceal adenocarcinomas.
  • Both groups A and B tumors shared a similar immunoprofile, which included generally focal immunoreactivity for neuroendocrine markers, and a normal intestinal type mucin glycoprotein profile (negative MUC1 expression and preserved MUC2 immunoreactivity).
  • The proliferative index was relatively low in these tumors and slightly increased from groups A to B tumors (11% to 16%).
  • Both beta-catenin and E-cadherin exhibited a normal membranous staining pattern in groups A and B tumors.
  • The overall disease-specific survival for all subtypes was 77%, with 46% of patients without evidence of disease and 31% alive with disease.
  • All the patients with clinical stage of I or IIA disease had a favorable outcome after appropriate surgery with or without chemotherapy.
  • Although most patients (63%) with GCC presented at an advanced clinical stage, their clinical outcome could be differentiated by subclassification of tumors.
  • In conclusion, GCC is a distinctive appendiceal neoplasm that exhibits unique pathologic features and clinical behavior.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Myeloid sarcoma of appendix mimicking acute appendicitis.
  • CONTEXT: Myeloid sarcoma is a neoplasm of immature myeloid cells involving an extramedullary anatomic site that is usually, although not always, associated with acute myeloid leukemia.
  • Any extramedullary site can be involved by myeloid sarcoma, but involvement of the cecal appendix is uncommon, and symptoms mimicking acute appendicitis as a result of appendiceal involvement are rare.
  • OBJECTIVE: To describe the clinicopathologic features of 2 patients with myeloid sarcoma involving the appendix who presented with right lower quadrant pain suggestive of acute appendicitis and prompting appendectomy.
  • Histologic examination of the appendix revealed poorly differentiated myeloid sarcoma in both cases.
  • Each neoplasm was positive for chloroacetate esterase, myeloperoxidase, lysozyme, and CD43 and was negative for CD3 and CD20.
  • CONCLUSIONS: Myeloid sarcoma involving the appendix can rarely cause pain or other symptoms mimicking acute appendicitis.
  • A high index of suspicion combined with the use of cytochemical and immunohistochemical studies are helpful in establishing the diagnosis.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Appendiceal mucinous cystadenoma is a neoplastic complication of IBD: case-control study of primary appendiceal neoplasms.
  • BACKGROUND: IBD is a risk factor for development of colorectal neoplasia.
  • Although IBD frequently involves the appendix microscopically, it is uncertain whether it also predisposes to appendiceal neoplasia.
  • METHODS: We performed a retrospective case-control study of incidental appendiceal neoplasms in colectomy specimens of adults with and without IBD (cases and controls, respectively) based on surgical pathology records spanning 54 months.
  • To minimize referral bias, patients were excluded if they had preoperative clinical evidence or a principal pathologic diagnosis of appendiceal disease.
  • RESULTS: Eleven appendiceal cystadenomas and 6 appendiceal carcinoid tumors were identified among 705 IBD cases (377 ulcerative colitis, 317 Crohn's disease, 11 indeterminate colitis) and 498 non-IBD controls meeting our inclusion criteria.
  • However, cyst adenomas were 15-fold more prevalent among cases with synchronous colorectal neoplasia compared with controls (4/69 [5.8%] versus 2/498 [0.4%], OR 15.3 [95% CI 2.7-85]) and 8-fold higher compared with cases without synchronous neoplasia (4/69 [5.8%] versus 5/636 [0.8%], OR 7.8 [95% CI 2.0-29.6]).
  • Appendiceal carcinoids were equally prevalent in cases and controls (4/705 [0.6%] versus 2/498 [0.4%], OR 1.4 [95% CI 0.3-7.8]), cases with synchronous neoplasia and controls (1/69 [1.4%] versus 2/498 [0.4%], OR 3.6 [95% CI 0.3-40.8]), and cases with and without synchronous colorectal neoplasia (1/69 [1.4%] versus 3/636 [0.5%], OR 3.1 [95% CI 0.3-30.2]).
  • CONCLUSIONS: IBD with synchronous colorectal dysplasia or cancer is a risk factor for development of appendiceal cystadenomas, implicating this tumor as a neoplastic complication of IBD.
  • IBD does not predispose to the development of appendiceal carcinoids.

  • [Title] Management of an unexpected appendiceal neoplasm.
  • BACKGROUND: Appendiceal neoplasms are rare and most present unexpectedly as acute appendicitis.
  • METHODS: A systematic literature review was performed to access relevant publications on the presentation, pathology and management of appendiceal tumours.
  • RESULTS: Appendiceal tumours account for 0.4 to 1 per cent of all gastrointestinal tract malignancies and are found in 0.7 to 1.7 per cent of appendicectomy specimens.
  • Most are cured by simple appendicectomy if the tumour is less than 2 cm in size and does not involve the resection margin or mesoappendix.
  • Epithelial tumours may present with, or in time develop, pseudomyxoma peritonei, the optimal management of which involves complete tumour resection and intraperitoneal chemotherapy, usually available only in specialized centres.
  • CONCLUSION: Suggested algorithms for the management of unexpected appendiceal tumours are provided.
  • Recommendations are made for follow-up of patients with a perforated appendiceal epithelial tumour.

  • [Title] Primary appendiceal carcinoma--epidemiology, surgery and survival: results of a German multi-center study.
  • BACKGROUND: While carcinoma of the colon is a common malignancy, primary carcinoma of the appendix is rare.
  • Many retrospective reviews outlined experience from different centers on appendiceal neoplasms.
  • The aim of this study was to analyze the type of surgery and survival of patients with appendiceal malignancies using data from a German multi-center observational study (31 341 patients).
  • METHODS: During a five-year period, 196 consecutive patients with malignant appendiceal tumors were distributed into four groups: appendiceal carcinoids, adenocarcinoma, mucinous adenocarcinoma and adenosquamous carcinoma.
  • Mean age at presentation was youngest for carcinoid tumors.
  • Carcinoid tumors had lowest tumor size and localized disease was present in 72.9%.
  • Overall 5-year survival was 83.1% for carcinoid vs. 49.2% for non-carcinoid tumors.
  • Histological subtype and tumor stage significantly affected survival.
  • CONCLUSIONS: Long-term outcome of carcinoid tumors is superior to non-carcinoid neoplasms.
  • Among all appendiceal neoplasms, adenosquamous carcinoma is the rarest histological subtype which is most commonly associated with advanced tumor stage and worst prognosis.
  • However, the high rate of right hemicolectomy in patients with small carcinoid tumors needs to be critically discussed.

  • Preoperative diagnosis is invariably difficult, and precise treatment protocols for these neoplasms remain unclear.
  • Other appendiceal pathologies were identified following hemicolectomy and oophorectomy.
  • However, small CCTs less than 2 cm in diameter at the tip of the appendix, with a low proliferative index, without angiolymphatic or mesoappendiceal extension can be treated by appendicectomy.
  • Following oncological assessment, further adjuvant therapy should be considered for patients with advanced disease.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Epithelial appendiceal neoplasms.
  • The appendiceal malignancies usually arise within a mucocele.
  • The tumor within this structure can be minimally aggressive or of an invasive character.
  • If a low-grade appendiceal malignancy is removed intact, recurrence does not occur.
  • If rupture of the wall of the mucocele occurs with either low-grade or high-grade disease, the epithelial cells within will disseminate to the peritoneal surfaces.
  • If the diagnosis of peritoneal dissemination of an appendiceal malignancy has been established, a new treatment with curative intent is indicated.
  • In approximately 900 patients treated at the Washington Cancer Institute, the quantitative prognostic indicators for appendiceal cancer with peritoneal dissemination have been determined.
  • Patients with a complete cytoreduction and low-grade tumor have an 80% survival at 20 years; with high-grade tumors, the survival drops to approximately 45%.
  • The extent of malignancy present within the abdomen by the peritoneal cancer index has a significant impact on survival for both high-grade and low-grade disease.
  • The most important indicator is the completeness of cytoreduction; for both high-grade and low-grade disease, all patients with an incomplete cytoreduction have died by 10 years.

64. Roy P, Chetty R: Goblet cell carcinoid tumors of the appendix: An overview. World J Gastrointest Oncol; 2010 Jun 15;2(6):251-8

  • [Title] Goblet cell carcinoid tumors of the appendix: An overview.
  • Goblet cell carcinoid is an enigmatic and rare tumor involving the appendix almost exclusively.
  • Since its identification in 1969, understanding of this disease has evolved greatly, but issues regarding its histogenesis, nomenclature and management are still conjectural.
  • Various other names have been used for this entity such as adenocarcinoid, mucinous carcinoid, crypt cell carcinoma, and mucin-producing neuroendocrine tumor, although none have been found to be completely satisfactory or universally accepted.
  • The tumor is thought to arise from pluripotent intestinal epithelial crypt-base stem cells by dual neuroendocrine and mucinous differentiation.
  • Recently molecular studies have shown these tumors to lack the signatures of adenocarcinoma but they have some changes similar to that of ileal carcinoids (allelic loss of chromosome 11q, 16q and 18q).
  • The natural history of GCC is intermediate between carcinoids and adenocarcinomas of the appendix.
  • The most important prognostic factor is the stage of disease.
  • There is some debate about the surgical approach for these tumors, and a summary of published series and recommendations are provided.

  • [Title] Analysis of metastatic ovarian tumors from extragenital primary sites.
  • AIMS AND BACKGROUND: The aim of this study was to evaluate patients with metastatic ovarian tumors from extragenital primary sites.
  • METHODS: The medical records of 75 patients were reviewed retrospectively for age at diagnosis, presenting symptoms, preoperative tumor marker levels, preoperative diagnostic workup, operative technique, intraoperative evaluation, frozen-section and pathology results, laterality of metastasis, and primary tumor site.
  • The specific impact of metastasis from colorectal and gastric primary sites on laterality, gross features and dimensions of ovarian mass, volume of ascites and tumor marker levels was investigated.
  • RESULTS: Primary sites were stomach (37.3%), colorectal region (28%), lymphoma (12%), breast (6.7%), biliary system (2.7%), appendix (1.3%) and small intestine (1.3%).
  • It was not possible to identify the primary tumor site in 8 (10.7%) patients.
  • Bilateral metastasis was found in 86.4% patients; 42.7% of the metastatic ovarian tumors were Krukenberg tumors; 50.7% of the ovarian masses were solid.
  • The mean preoperative serum levels of tumor markers were 298.7 U/mL, 178 U/mL and 113.3 U/mL for CA 125, CA 19-9 and CA 15-3, respectively.
  • The presence of ascites was more frequent in ovarian tumors originating from colorectal and gastric primaries.
  • CONCLUSIONS: Surgery is essential for the diagnosis of the primary tumor and necessary for relief of symptoms.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Cytokeratins 7 and 20 immunoexpression profile in goblet cell and classical carcinoids of appendix.
  • Goblet cell carcinoid (GCC) of the vermiform appendix is an uncommon neoplasm and its histogenesis is controversial.
  • Whether GCC represents a morphological variant of classical appendiceal carcinoid or a mucin-producing adenocarcinoma is still conjectural.
  • Little is known about the immunohistochemical expression of cytokeratins 7 (CK7) and 20 (CK20) in appendiceal neuroendocrine tumors.
  • In this study, we compared the expression of CK7 and CK20 in 17 cases of appendiceal GCC and 25 cases of classical carcinoid.
  • The tumors were also evaluated for Ki-67 proliferation index, mitotic activity, tumor necrosis, extracellular pools of mucin, obvious intestinal type adenocarcinomatous foci, angiolymphatic permeation, perineural/neural infiltration, and the depth of invasion of the appendix wall.
  • Immunohistochemically, all 17 (100%) of GCC exhibited strong and diffuse immunopositivity for CK20, whereas expression of CK7 was present in 12 cases (70.5%), ranging from 5 to 50% of tumor cells being labeled.
  • On the other hand, 25 cases of classical carcinoid tumors were consistently negative for CK7; however, 4 cases (16%) showed immunolabeling for CK20 in 25-50% of the tumor cells.
  • Goblet cell carcinoid should be regarded as a crypt cell or an amphicrine carcinoma rather than a variant of carcinoid tumor, a lesion that has benign connotations.

  • [Title] Appendiceal neoplasms with peritoneal dissemination: outcomes after cytoreductive surgery and intraperitoneal hyperthermic chemotherapy.
  • BACKGROUND: Appendiceal neoplasms frequently present with peritoneal dissemination (PD) and have a clinical course marked by bowel obstruction and subsequent death.
  • Few data have correlated outcome with appendiceal histology after cytoreductive surgery and intraperitoneal hyperthermic chemotherapy (IPHC).
  • We have reviewed our experience with cytoreductive surgery and IPHC for PD from the appendix.
  • METHODS: A total of 110 cases of PD from proven appendiceal neoplasms treated with IPHC were identified from a prospectively managed database.
  • Tumor samples were classified on pathologic review as disseminated peritoneal adenomucinosis (n = 55), peritoneal mucinous carcinomatosis (PMCA) with intermediate features (n = 18), PMCA (n = 29), or high-grade nonmucinous lesions (n = 8).
  • RESULTS: A total of 116 IPHCs were performed on 110 patients for appendiceal PD between 1993 and 2004.
  • When stratified by histology, disseminated peritoneal adenomucinosis and intermediate tumors had better 3-year survival rates (77% +/- 7% and 81% +/- 10%) than PMCA and high-grade nonmucinous lesions (35% +/- 10% and 15% +/- 14%; P = .0032 for test of differences between groups).
  • Age at presentation (P = .0134), performance status (P < .0001), time between diagnosis and IPHC (P = .0011), resection status (P = .0044), and length of hyperthermic chemoperfusion (P = .0193) were independently associated with survival.
  • CONCLUSIONS: The data show that long-term survival is anticipated in most patients who are treated with cytoreduction and IPHC for appendiceal PD.
  • In all, this work establishes a framework for the consideration of IPHC in future trials for appendiceal PD.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Hepatic metastases of primary jejunal carcinoid tumor: A case report with radiological findings.
  • CONTEXT: Carcinoid tumors represent a group of well-differentiated tumors originating from the diffuse endocrine system outside the pancreas and thyroid.
  • The overall prevalence of carcinoid tumors in the United States is estimated to be one to two cases per 100,000 persons.
  • Various sites of origin of this neoplasm are appendix - 30-45%, small bowel - 25-35% (duodenum 2%, jejunum 7%, ileum 91%, multiple sites 15-35%), rectum 10-15%, caecum - 5%, and stomach - 0.5%.
  • CASE REPORT: Here we report a case of primary jejunal carcinoid tumor in a 66-year-old woman metastasizing to liver with ultrasonography, computed tomography, and diffusion-weighted magnetic resonance imaging (DWI) findings.
  • CONCLUSION: Primary jejunal carcinoid tumor is a rare entity.
  • DWI can help in the differential diagnosis of hepatic hypervascular metastatic mass lesions from benign ones, as well as in the diagnosis of carcinoid tumor.

  • [Title] Incidence of synchronous appendiceal neoplasm in patients with colorectal cancer and its clinical significance.
  • BACKGROUND: The aims of this study were to evaluate the incidence of synchronous appendiceal neoplasm in patients with colorectal cancer, and to determine its clinical significance.
  • METHODS: Pathological reports and medical records were reviewed of patients with colorectal adenocarcinoma who underwent oncological resection of the tumor together with appendectomy at the Faculty of Medicine Siriraj Hospital, Mahidol University, Thailand between September 2000 and April 2008.
  • One patient (0.3 percent) had epithelial appendiceal neoplasm (mucinous cystadenoma) and 3 patients (1.0 percent) had metastatic colorectal cancer in the mesoappendix.
  • However, the presence of synchronous appendiceal tumors and/or metastasis did not alter postoperative management, as these patients had received adjuvant therapy and were scheduled for surveillance program because of nodal involvement.
  • CONCLUSION: The incidence of synchronous primary appendiceal neoplasm and secondary (metastatic) appendiceal neoplasm in colorectal cancer patients was 0.3 and 1.0 percent, respectively.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Establishment and characterization of a murine xenograft model of appendiceal mucinous adenocarcinoma.
  • We describe the clinical, pathologic and molecular characteristics of a xenograft model of metastatic mucinous appendiceal adenocarcinoma.
  • Tumours from patients with mucinous appendiceal neoplasms were implanted in nude mice and observed for evidence of intraperitoneal tumour growth.
  • Morphologic and immunohistochemical features, temporal growth characteristics relative to controls, and loss of heterozygosity (LOH) at multiple chromosomal alleles were assessed in a successfully engrafted tumour.
  • The successful xenograft is morphologically similar to the original tumour, produces abundant extracellular mucin and exhibits non-invasive growth on peritoneal surfaces.
  • The temporal growth characteristics of the xenograft tumour relative to controls reveal that tumour burden can be followed indirectly by measuring the weight or abdominal girth of engrafted animals.
  • The cytokeratin, mucin core protein, CDX2, Ki-67 and p53 expression patterns are identical in the xenograft and resected tumour and are consistent with the expected pattern of protein expression for mucinous adenocarcinoma of the appendix.
  • LOH was found in 1 of 10 informative chromosomal loci (chromosome 10p23) in xenograft tumour cells.
  • Although we were unable to engraft a low-grade appendiceal mucinous neoplasm, the engrafted adenocarcinoma will be useful for future evaluation of novel therapeutic strategies directed at mucinous appendiceal adenocarcinoma and evaluation of strategies for treating widespread, bulky, mucinous peritoneal surface neoplasms.
  • Xenograft tumour enrichment can facilitate molecular studies of appendiceal epithelial neoplasia.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] A retrospective clinico-pathological analysis of neuroendocrine tumors of the gastrointestinal tract.
  • AIM: Gastrointestinal tract is the commonest site for neuroendocrine tumors.
  • Appendix, ileum and rectum were considered to be common sites for these tumors.
  • However, there has been change in pattern of gastrointestinal neuroendocrine tumors over last few years.
  • There is limited data available on epidemiology and patterns of these tumors in India.
  • METHODS: Analysis of 74 patients with gastrointestinal and pancreatic neuroendocrine tumors over a period of 7 years at a single center in Mumbai, India was done.
  • All these patients were analyzed with special emphasis on the site of the tumor.
  • Of the 74 tumors, the commonest site was found to be stomach 22 (30.2%), followed by pancreas 17 (23.3%) and duodenum 14 (18.9%).
  • The disease was localized in 46 (62.2%), regional spread was seen in 14 (18.9%) and distant spread in 14 (18.9%).
  • Majority of gastric and duodenal tumors had localized disease while pancreatic NETs led to most of the cases with distant disease.
  • CONCLUSION: This analysis showed that gastrointestinal and pancreatic neuroendocrine tumors are not rare.
  • Pattern of these tumors has definitely changed over last few years.
  • Stomach was found to be commonest site for gastrointestinal neuroendocrine tumors followed by pancreas and duodenum.

  • INTRODUCTION: Carcinoid tumor is a rare neuroendocrine neoplasm with different locations, the most frequent ones during the pediatric age being the appendix and lung.
  • Scintigraphy with (111)In-DTPA-d-Phe(1)-octreotide has led to an importance advance in the diagnosis of extension in carcinoid tumor patients.
  • CLINICAL CASES: The first patient (9 years) was studied using the SSRS after surgery due to carcinoid tumor in the right lower lobe in which tumor remains was observed (this being clearer in the tomography study).
  • The second patient (10 years) presented due to endobronchial tumor in the left lower lobe together with atelectasis of the LUL and emphysema of the LLL.
  • Radiology imaging techniques suggested the differential diagnosis between the endobronchial carcinoid tumor or plasma cells or foreign body gramuloma.
  • The SSRS showed an abnormal deposit of activity in the left hemithorax consisted with carcinoid tumor.
  • After the surgery (endobronchial resection), new controls with SSRS showed absence of disease.
  • CONCLUSION: The SSRS has demonstrated great utility in the diagnosis, follow-up and staging of pediatric patients, carriers of neuroendocrine carcinoid tumors.

  • [Title] Combined adenocarcinoid and mucinous cystadenoma of the appendix: a case report.
  • INTRODUCTION: Adenocarcinoid of the appendix is a rare malignant tumour with features of both adenocarcinoma and carcinoid, showing both epithelial and endocrine differentiation.
  • Mucinous cystadenoma is the commonest of the benign neoplasms of the appendix, with an incidence of 0.6% in appendicectomy specimens.
  • Laparoscopy revealed an adenocarcinoid of the appendix in combination with mucinous cystadenoma.
  • CONCLUSION: Adenocarcinoids account for 2% of primary appendiceal malignancies.
  • Right hemicolectomy is generally advised if any of the following features are present: tumours greater than 2 cm, involvement of resection margins, greater than 2 mitoses/10 high-power fields on histology, extension of tumour beyond serosa.
  • Chemotherapy mostly with 5-Fluorouracil and Leucovorin is advised for remnant disease after surgery.

  • [Title] Appendiceal mucinous neoplasms: clinicopathologic study of 116 cases with analysis of factors predicting recurrence.
  • The classification and nomenclature of appendiceal mucinous neoplasms are controversial.
  • To determine the outcome for patients with appendiceal mucinous neoplasms and further evaluate whether they can be stratified into groups that provide prognostic information, the clinicopathologic features of 116 patients (66 with clinical follow-up) with appendiceal mucinous neoplasms were studied.
  • From a wide variety of histopathologic features assessed, the important predictors that emerged on univariate statistical analysis were presence of extra-appendiceal neoplastic epithelium (P=0.01), high-grade cytology (P<0.0001), architectural complexity (P<0.001), and invasion (P<0.001).
  • All 16 patients with mucinous neoplasms confined to the appendix and lacking high-grade cytology, architectural complexity, and invasion were alive with no recurrences at median 59 months follow-up (=mucinous adenoma).
  • One of 14 patients with low-grade cytology and acellular peritoneal mucin deposits developed recurrent tumor within the peritoneum at 45 months with no patient deaths to date (median, 48-mo follow-up) (=low-grade mucinous neoplasm with low risk of recurrence).
  • Twenty-seven patients with low-grade mucinous neoplasms with extra-appendiceal neoplastic epithelium had 1-year, 3-year, 5-year, and 10-year overall survival rates of 96%, 91%, 79%, and 46%, respectively, at median 53 months follow-up (=low-grade mucinous neoplasm with high risk of recurrence).
  • Three of the 4 patients with extra-appendiceal epithelium limited to the right lower quadrant developed full-blown peritoneal disease at 6, 41, and 99 months follow-up and 1 patient eventually died of disease.
  • Nine patients with appendiceal neoplasms with invasion or high-grade cytology and follow-up showed 1-year, 3-year, and 5-year overall survival rates of 86%, 57%, and 28% (=mucinous adenocarcinoma).
  • Appendiceal mucinous neoplasms can be stratified into 4 distinct risk groups on the basis of a careful histopathologic assessment of cytoarchitectural features and extent of disease at presentation.

  • We report the rare occurrence of an inflammatory fibroid polyp of the appendix.
  • CT-scan showed an 8 cm appendiceal mass and a laparoscopic appendectomy was consequently performed.
  • On microscopic examination, the tumor consisted of spindle cells dispersed in a loose fibromyxoid stroma containing numerous blood cells and inflammatory cells with abundant eosinophils.
  • On immunohistochemistry, the spindle tumor cells were positive for vimentin, fascin and focally for CD34 and CD35.
  • Inflammatory fibroid polyp is a rare benign mesenchymal tumor of the gastrointestinal tract rarely reported in the appendix.
  • This tumor shares some common pathologic features with the myofibroblatic inflammatory tumor but they are two different entities.
  • The pathogenesis of this tumor remains unclear but fascin and CD35 immunoreactivity of the tumor cells suggests a probable dendritic cell origin.

  • [Title] Clinical characteristics and prognostic factors for primary appendiceal carcinoma.
  • AIM: Primary adenocarcinoma of the appendix is a rare malignancy.
  • This study assessed prognostic factors affecting the clinical outcome in patients with appendiceal neoplasms.
  • The distribution of stages was: 26 (47.3%) with localized disease, five (9.1%) with regional disease, and 24 (43.6%) with distant metastatic disease.
  • Of the 34 patients who underwent curative resections of primary appendiceal carcinomas, the 3- and 5-year disease-free survival rates were 66.4% and 53.3%, respectively.
  • The recurrence rate was higher in patients with regional lymph node metastasis (HR vs node negative disease 23.4; P = 0.005) and high-grade tumors (HR vs low grade 6.3; P = 0.029).
  • CONCLUSION: High tumor grade and advanced stage were significantly predictive of poor survival outcome in patients with primary appendiceal carcinomas.

  • Carcinoid tumors are slow-growing and usually become symptomatic late in the course of the disease.
  • We evaluated our 10-year experience in the management of GI carcinoid tumors.
  • The rectum was the most common site for carcinoid tumors with an incidence of 30 per cent followed by jejunoileal at 29.3 per cent.
  • Other sites of carcinoid tumors were the appendix (8.3%), colon (8.3%), and duodenum (3.8%).
  • CT was not helpful in preoperative diagnosis of carcinoid tumor.
  • Fifteen patients died in follow-up with eight deaths related to carcinoid tumors, in the small bowel (6), rectum (1), and colon (1).
  • Overall survival was 68.7 per cent and mortality rate was 19.5 per cent from carcinoid tumors.
  • Most of the deaths occurred in patients with carcinoid syndrome, synchronous malignancy, and malignant carcinoid tumors.
  • The mean disease-free survival was 51 months (range, 15 to 138 months).
  • Screening colonoscopy, in addition to decreasing colorectal adenocarcinoma mortality, is useful in diagnosing carcinoid tumors at an earlier stage and in decreasing mortality from malignant colorectal carcinoid tumors.

  • [Title] Systematic evaluation of the intraoperative tumor pattern in patients with borderline tumor of the ovary.
  • OBJECTIVE: Borderline ovarian tumors (BOTs) are rare entities with excellent prognosis depending on tumor stage and presence of invasive implants.
  • There are limited data regarding the intraoperative tumor pattern, the actual base of optimal treatment planning.
  • We conducted a systematic evaluation of the macroscopic and microscopic tumor spreads in patients with BOTs with special focus on the diagnosis of invasive and noninvasive lesions.
  • Complete tumor resection was achieved in 47 patients (92.15%), whereas mean (SD) operative time was 126.34 (73.4) minutes.
  • Sixteen patients (31.37%) presented extraovarian involvement into the peritoneum (23.5%), omentum (17.7%), uterus (7.84%), sigmoid (7.8%), lymph nodes (7.8%), ileum (3.9%), mesentery (5.9%), and appendix (1.96%).
  • CONCLUSIONS: Borderline ovarian tumors require a systematic surgical evaluation to verify or exclude extrapelvic tumor lesions and allow further clinical relevant differentiation between invasive and noninvasive implants.

  • [Title] Primary ovarian mucinous tumors with signet ring cells: report of 3 cases with discussion of so-called primary Krukenberg tumor.
  • The distinction between a primary ovarian mucinous carcinoma or even a borderline mucinous tumor and a metastatic mucinous carcinoma may be difficult.
  • One of the most important morphologic features suggesting a metastatic mucinous carcinoma in the ovary is the presence of signet ring cells; these are considered rare in primary ovarian mucinous tumors.
  • In this study, we report 3 primary ovarian mucinous tumors with a component of signet ring cells.
  • The tumors arose in patients aged 27, 55, and 60, were unilateral, confined to the ovary and stage IA.
  • In one case, the neoplasm had the architecture of a mucinous adenofibroma but had frankly malignant cells lining glands and forming solid aggregates of cells.
  • A second tumor also had the background of an adenofibroma.
  • Investigations to exclude a gastrointestinal neoplasm in 2 cases were negative.
  • Features favoring a primary rather than a metastatic neoplasm are unilateral tumor, low stage, background of adenofibroma or cystadenoma, associated endometriosis in 1 case and an absence of features which are characteristic of secondary mucinous carcinomas in the ovary, such as surface tumor deposits, a nodular growth pattern, and lymphovascular permeation.
  • Immunohistochemistry is of limited value because of overlapping immunophenotype between a primary ovarian mucinous tumor and a metastasis from the stomach, pancreas, biliary tree, appendix, or colorectum, the most likely primary sites for a secondary exhibiting similar features.
  • Our study illustrates that signet ring cells occur rarely in a primary ovarian mucinous tumor; even when conspicuous the features differ from those of the usual Krukenberg tumor.
  • At least some cases of so-called primary Krukenberg tumor may be similar to our cases.
  • However, the designation primary Krukenberg tumor should not be used as, apart from the signet ring cells, a resemblance to a "true" Krukenberg tumor of the secondary type is limited.
  • The tumors should be classified according to the underlying background neoplasm with a notation concerning the signet ring cell component.

  • Mucinous cystadenomas of the appendix are rare tumours.
  • At laparotomy we found a dilatation of the appendix which contained an abundant quantity of mucus.
  • Histological examination showed a mucinous cystadenoma of the appendix.
  • This neoplasm requires a surgical treatment, usually only appendectomy and right hemicolectomy in case of involvement of the caecum.
  • During operation, the surgeon must take care in handling the appendix because of the risk of rupture with consequent dissemination of epithelial cells in the peritoneal cavity (pseudomyxoma peritonei).

  • [Title] Surgical treatment of appendiceal adenocarcinoid (goblet cell carcinoid).
  • Adenocarcinoid of the appendix is an infrequent tumor with histologic features of both adenocarcinoma and carcinoid tumor.
  • The aim of this study was to analyze long-term results of surgical treatment for appendiceal adenocarcinoid.
  • A retrospective review (1991-2003) identified seven patients (median age 72, range 27-81 years) treated for appendiceal adenocarcinoid.
  • Indications for colectomy were tumor size (three cases) associated with appendectomy margin invasion in one case.
  • One patient with lymph node and peritoneal involvement experienced recurrence 9 months after hemicolectomy and died of the disease at 2 years.
  • Five patients were alive without disease at the time of the last follow-up.
  • Our results suggest that appendectomy alone could be used for appendiceal adenocarcinoid provided that the tumor (1) is less than 1 cm;.
  • (2) does not extend beyond the appendix adventitia;.
  • (3) has less than 2 mitoses/10 high power fields; and (4) has surgical margins that are tumor free.
  • The risk for developing colorectal adenocarcinoma seems to be extremely high in patients treated for appendiceal adenocarcinoid and warrants close follow-up with colonoscopic screening.

  • Primary hepatic yolk sac tumour (YST) is a very rare neoplasm.
  • From laparoscopic appendectomy there was bioptically verified a diagnosis of YST.
  • Consequently, there was discovered a tumor in the liver and the patient underwent right hemihepatectomy, hemicolectomy and ovariectomy, from which the YST was disclosed in the liver and in the coecum with spread into regional lymph nodes.
  • While the gonadal, mediastinal and central nervous system origin of the YST was excluded, the diagnosis of the primary hepatic YST could have been established.
  • This tumour is aggressive with ability to spread into distant sites, where it can lead to the first clinical presentation.

  • [Title] Ruptured appendiceal diverticula mimicking low-grade appendiceal mucinous neoplasms.
  • Low-grade appendiceal mucinous neoplasms may rupture and seed the peritoneum with bland neoplastic mucinous epithelium resulting, when grossly evident, in the well-known process pseudomyxoma peritonei.
  • Appendiceal diverticula may also rupture, resulting in mucin on the appendiceal serosa, which may raise concern for an underlying appendiceal mucinous neoplasm.
  • We report 11 cases of ruptured appendiceal diverticula that were initially either misdiagnosed as appendiceal mucinous neoplasms, raised concern for a neoplasm, or were thought to exhibit localized pseudomyxoma peritonei.
  • Two cases showed eversion of the appendiceal lining onto the serosa; 1 showed collision between the diverticulum and endosalpingiosis, and 3 had rare nonneoplastic epithelial cells in extra-appendiceal mucin.
  • Pathologists should be aware that ruptured appendiceal diverticula may be associated with serosal mucin and even extra-appendiceal epithelium.
  • Failure to distinguish this process from a mucosal neoplasm with rupture may result in unnecessary therapy and cause the patient undue alarm.

  • [Title] The porta hepatis as a site of recurrence of mucinous appendiceal neoplasms treated by cytoreductive surgery and perioperative intraperitoneal chemotherapy.
  • BACKGROUND: A successful new treatment for a particular disease may change the natural history of that disease as patients go on to longer survival.
  • The goal of this study was to investigate the porta hepatis as a site of recurrence of appendiceal mucinous neoplasms.
  • METHODS: A prospective database on patients with peritoneal dissemination of mucinous appendiceal neoplasms has been maintained for 21 years.
  • In patients with complete cytoreduction, disease progression/recurrence in and around the porta hepatis has been noted as a new manifestation of this disease.
  • RESULTS: In 710 patients treated for mucinous appendiceal cancer with a complete cytoreduction, 140 developed recurrent disease.
  • Seven patients (5%) had disease recurrence in and around the porta hepatis.
  • CONCLUSIONS: Progression of mucinous neoplasms within the porta hepatis may be related to imperfect cytoreduction technique.

  • Herein, we report a case of a 73-year-old man without symptoms who was initially diagnosed with a pancreatic cystic tumor but later with XGI in the peripancreatic region.
  • Although XGI has been reported to occur in various organs or tissues, such as the gallbladder, kidney, bone, stomach, colon, appendix, lymph nodes, and soft tissues, XGI involving the pancreas or its surrounding tissues is extremely rare.
  • When a pancreatic cystic lesion does not have typical clinicoradiological features of common pancreatic cystic neoplasms, this pathologic condition should be considered in the differential diagnosis.
