  • [Title] Carcinoid tumors of appendix: treatment and outcome.
  • 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] Carcinoid tumour of the appendix: an analysis of 1,485 consecutive emergency appendectomies.
  • AIM: The aim of this study is to conduct a retrospective analysis of the incidence and long-term results of carcinoid tumours of the appendix in emergency appendectomies.
  • RESULTS: In three women and four men, carcinoid tumours were identified (0.47%).
  • Four patients underwent ileocecal resection; one other patient underwent right hemicolectomy.
  • In none of the re-operation specimens was residual carcinoid tumour detected.
  • CONCLUSION: Carcinoid tumours of the appendix most often present as acute appendicitis.
  • It also emphasises the value of histopathological analysis of every removed appendix.
  • The long-term prognosis of incidentally found carcinoids of the appendix is good.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Laparoscopic versus open resection for appendix carcinoid.
  • BACKGROUND: Since an increasing number of appendectomies are performed via laparoscopy, it is crucial to determine the impact of this approach on appendix carcinoid (AC) outcome.
  • Median carcinoid size was 1.1 cm (range, 0.3-5) and 0.4 cm (range, 0.2-3) in the LAP and OP groups, respectively.
  • Two patients died in the OP group, one due to metastatic carcinoid and the other due to metachronous colorectal cancer.
  • Prognosis of AC appears more dependent on carcinoid malignant potential or associated tumors.

6. 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.
  • While its malignant potential remains unclear, GCC's are more aggressive than conventional carcinoid.
  • This review summarizes the published literature on GCC of the appendix.
  • 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.
  • 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.

  • [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.
  • We report a case of a carcinoid tumour in the tip of the appendix of a thirteen year old girl which was diagnosed intraoperatively.

  • [Title] Application of light microscopical and ultrastructural immunohistochemistry in the study of goblet cell carcinoid in the appendix.
  • BACKGROUND: Goblet cell carcinoids appear less frequently in the appendix than do other carcinoids.
  • In the presented work a case with a goblet cell carcinoid of the appendix is described.
  • METHODS: Routine histological and histochemical methods were employed, with a combination of histochemistry and immunohistochemistry on one section and light and electron microscopical immunohistochemisty on paraffin-embedded material, were applied to identify the type of the carcinoid and to reveal the fine structure of cell types in the tumour nests of the appendix.
  • RESULTS: During the biopsy of a patient who had undergone appendectomy, an infiltration with clusters of goblet cells in the submucosa of the appendix was found.
  • The ultrastructural immunohistochemistry showed that chromogranin A-positive cells had discoid and pleomorphic granules and were located in tumour nests or as single cells in the appendiceal wall.
  • CONCLUSION: The combined histochemical and immunohistochemical procedure and the ultrastructural immunohistochemistry on archival material could contribute in clarifying the diagnosis of goblet cell carcinoid.

  • INTRODUCTION: Appendiceal carcinoids are the most frequent tumors of the appendix and are usually detected as an incidental finding in the final pathology report.
  • The aim of this study was to evaluate the clinical and pathological characteristics, surgical treatment and long-term survival in patients with an appendiceal carcinoid tumor.
  • MATERIAL AND METHODS: We performed a retrospective study of patients treated from 1980 to 2007 with a pathological diagnosis of appendiceal carcinoid tumor.
  • Carcinoid tumor was diagnosed in 40 patients (25 women and 15 men), aged 37+/-18 years old.
  • The tumor was localized in the distal third of the appendix in 24 patients (60%), and the size of the tumor was less than 1cm in 28 (70%).
  • Twenty-nine (72.5%) of these tumors infiltrated the subserosal and/or the serosal layer.
  • CONCLUSIONS: Appendiceal carcinoid tumor is usually detected incidentally in the pathological analysis in patients undergoing surgery for suspected appendicitis.

  • 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.

  • [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.
  • 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.
  • 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.

  • [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.
  • 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.
  • 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.

  • Goblet cell carcinoid of the appendix is a rare neoplasm and clinically tends to take a malignant course.
  • Abdominal computed tomography showed massive ascites and slight contrast enhancement of appendix.
  • 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.
  • It is thought that intraabdominal paclitaxel administration and systemic S-1 therapy can be one of appropriate forms of chemotherapy for inoperable peritoneal carcinomatosis from goblet cell carcinoid of appendix.

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:.
  • (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.

  • [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.
  • The tumors (0.6 to 6.0 cm) were located in the mid-portion and the tip of the appendix.
  • 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.
  • Both components stained for the general neuroendocrine markers, however, staining in the classic component was greater.
  • 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.

  • [Title] Clear cell carcinoid of the appendix: an uncommon variant of lipid-rich neuroendocrine tumor with a broad differential diagnosis.
  • The designation of clear cell/lipid-rich refers to an unusual variant of neuroendocrine tumor ("carcinoid") described in several organs, but only recently observed in the appendix.
  • In this study, we report the morphologic, immunohistochemical, and ultrastructural features of an incidentally discovered appendiceal clear cell/lipid-rich carcinoid in a 32-year-old man without any evidence of von Hippel-Lindau disease.
  • Differential diagnosis with mimicking neoplastic and non-tumor lesions, epidemiology, and clinical behavior of this exceedingly rare variant of carcinoid of the appendix are also discussed.

  • [Title] Laparoscopic two-stage surgery for goblet cell carcinoid of the appendix: report of a case and review of the Japanese literature.
  • Goblet cell carcinoid of the appendix is a rare clinical entity exhibiting features of both carcinoid and adenocarcinoma.
  • Here, we present the first report of laparoscopic 2-stage surgery for goblet cell carcinoid with a review of the Japanese literature.
  • A pathologic diagnosis of goblet cell carcinoid, accompanied by the aggressive proliferation, with acute appendicitis was made.
  • Subsequent laparoscopic ileocecal resection was performed, and it was verified that there were neither residual tumor nor lymph node metastases.
  • Because goblet cell carcinoid may be difficult to clinically distinguish from acute appendicitis, pathologic examination is essential.
  • Depending upon the grade of tumor proliferation, additional resection should be considered, and our experience with this case suggests that laparoscopic 2-stage surgery is feasible for the adequate treatment of goblet cell carcinoid without complications.

  • [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.
  • Sixteen (0.82%) patients had carcinoid tumours.
  • 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).
  • None of the carcinoid tumours were identified at operation.
  • CONCLUSIONS: Carcinoid tumour of the appendix remains an incidental diagnosis.
  • Patients with carcinoids were significantly older than non-carcinoid conditions.
  • There was a trend of increased occurrence of carcinoids amongst the females.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.

  • 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.
  • Treatment for lesions 1-2 cm is controversial and needs further characterization of the tumour (i.e. mesoappendiceal invasion, vascular invasion, mitotic activity, proliferation markers) and careful patient risk evaluation.
  • Goblet-cell carcinoids have features resembling both carcinoid and adenocarcinoma and should be treated by hemicolectomy.
  • Overall prognosis of small appendiceal NET is excellent in all ages.

  • [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: laparoscopic appendectomy or right hemicolectomy?
  • Goblet cell carcinoids are uncommon tumours with histological features of both adenocarcinoma and carcinoid tumour.
  • They occur predominantly in the appendix and although the malignant potential remains unclear, adenocarcinoids appear to be more aggressive than conventional carcinoids.
  • In this case report, we present a goblet cell carcinoid with laparoscopic operative treatment in two stages.
  • Macroscopically, a diffusely inflamed appendix was found with no sign of perforation.
  • Histopathological examination revealed a goblet cell carcinoid with characteristics of aggressive behaviour, indicating the need for laparoscopic right hemicolectomy in which, however, neither residual tumour nor metastatic lymph nodes could be found.
  • As they may present the same clinical presentation, pathological diagnosis is required to distinguish goblet cell carcinoid from acute appendicitis.
  • Two-stage surgery for goblet cell carcinoid is advocated in the literature, but the debate still continues as to whether the goblet cell carcinoid should be treated by appendectomy alone, as for most carcinoids, or by right hemicolectomy, as for the appendiceal adenocarcinoma.

  • [Title] Carcinoid of the vermiform appendix. Description of three clinical cases and review of the literature.
  • [Transliterated title] Carcinoide dell'appendice vermiforme.
  • Carcinoids of the appendix represent a separate class of tumours with characteristics that vary between benign (adenomas) and malignant (carcinomas) neoplasias.
  • A recent nomenclature identifies them as diffuse neuroendocrine system (DNS) and/or, parallely, as neuroendocrine tumours (NET): the gastroenteric tract is the site of about 64.3% of carcinoids, followed by the respiratory tract with 25.3%.
  • Among the gastrointestinals, tumour of the small intestine is the one with the highest incidence with 28.5%, followed by the appendix with 4.77%, the rectum with 13.6% and the stomach with 4.6%.
  • Carcinoid of the colon has an incidence of 8.62%, with the caecum which alone represents 34.5% of colic localisations.
  • The 3 cases described are an example of the behavioural unpredictability of intestinal carcinoids.
  • The first case is that of a female patient in whom the primary tumour was only discovered after liver metastasis was documented.
  • Subsequent investigations carried out in the postoperative period documented the presence of liver metastasis at the V and VI liver segments.
  • The last case, similar to the second from certain points of view, shows the need to carry out a right hemicolectomy with removal of locoregional lymphnodes in the event of an appendicular carcinoid >2 cm.
  • Both laboratory and instrumental examinations contribute to the diagnosis of intestinal carcinoid.
  • First level instrumental examinations for the diagnosis of intestinal carcinoid are represented by CT with and without contrast medium, diagnostic endoscopy and, to better highlight the presence of locoregional metastases, scintigraphy with octreotide and PET.
  • Treatment with somatostatin, on the other hand, proved effective in controlling tumour secretion, so attenuating the inconveniences of carcinoid syndrome.

  • AIM: To report the experience of the CHU Sart Tilman, University of Liege, Belgium, in the management of appendiceal carinoid tumor.
  • RESULTS: Among the 1237 appendectomies, 5 appendiceal carcinoid tumors were identified (0.4%) in 4 male and 1 female patients, with a mean age of 29.2 years (range: 6-82 years).
  • All tumors were located at the tip of the appendix with a mean diameter of 0.6 cm (range: 0.3-1.0 cm).
  • CONCLUSION: Appendiceal carcinoid tumor most often presents as appendicitis.
  • Appendiceal carcinoid tumor can be managed by simple appendectomy and resection of the mesoappendix, if its size is <or=1 cm.

  • [Title] Carcinoid tumors of the appendix: are these tumors identifiable prospectively on preoperative CT?
  • The purpose of this study was to determine if carcinoid tumors of the appendix were identified prospectively on preoperative CT at our institution during the last decade.
  • A surgical database search performed using the Current Procedural Terminology codes for appendectomy and colectomy yielded 2108 patients who underwent appendectomy or colectomy with removal of the appendix from January 1998 through September 2007.
  • Pathology reports were reviewed to identify patients in whom an appendiceal carcinoid tumor was identified.
  • Twenty-three carcinoid tumors (1.1%; 15 women [65.2%], eight men [34.8%]; average age 54 years [range, 23 to 86 years]) were identified.
  • No tumors were identified prospectively on CT.
  • Average reported tumor size was 6.1 mm (range, 1.5 to 15 mm; n = 18).
  • A tip or distal location was reported for all tumors for which a location was given (n = 15).
  • Carcinoid tumors occurred in 1.1 per cent of appendix specimens.
  • These tumors were all less than or 1.5 cm in size.
  • Likely as a result of their small size, none of these tumors was identified prospectively on preoperative CT.

  • [Title] Goblet cell carcinoid of the appendix: a specific type of carcinoma.
  • AIMS: Goblet cell carcinoid is a poorly understood tumour of the appendix.
  • The aim of this study was to determine whether it should be regarded as a separate entity or as a variant of classical carcinoid.
  • METHODS AND RESULTS: The immunohistochemical expression pattern of 21 markers and the mutation status of KRas codon 12 were determined in 16 goblet cell carcinoids and compared with 14 classical carcinoids, 19 colonic adenocarcinomas and 10 appendiceal mucinous cystadeno (carcino)mas.
  • Goblet cell carcinoids were significantly different from the control groups.
  • The most important markers for discriminating between the groups were CEA (classical carcinoid versus all others), KRas mutation (present in all mucinous cystadeno (carcino)mas), beta-catenin (goblet cell carcinoid versus left sided colonic adenocarcinoma) and chromogranin (goblet cell carcinoid versus right sided colonic adenocarcinoma).
  • Expression of Math1 and HD5 was similar in goblet cell carcinoid and colonic adenocarcinoma but absent in classical carcinoid.
  • CONCLUSION: The results suggest that goblet cell carcinoids should be regarded as a separate entity.
  • The formerly used term 'crypt cell carcinoma' may be more appropriate because it reflects the more aggressive clinical behaviour of these tumours as well as their greater similarity to adenocarcinomas rather than to carcinoids.

  • [Title] Tachykinins in endocrine tumors and the carcinoid syndrome.
  • OBJECTIVE: A new antibody, active against the common tachykinin (TK) C-terminal, was used to study TK expression in patients with endocrine tumors and a possible association between plasma-TK levels and symptoms of diarrhea and flush in patients with metastasizing ileocecal serotonin-producing carcinoid tumors (MSPCs).
  • METHOD: TK, serotonin and chromogranin A (CgA) immunoreactivity (IR) was studied by immunohistochemistry in tissue samples from 33 midgut carcinoids and 72 other endocrine tumors.
  • Circulating TK (P-TK) and urinary-5 hydroxyindoleacetic acid (U-5HIAA) concentrations were measured in 42 patients with MSPCs before treatment and related to symptoms in patients with the carcinoid syndrome.
  • TK-IR was also seen in all serotonin-producing lung and appendix carcinoids.
  • None of the other tumors examined contained TK-IR cells.
  • CONCLUSION: We found that TK synthesis occurs in serotonin-IR tumors and that P-TK levels are significantly correlated with symptoms of flush and diarrhea in patients with MSPCs.
  • This is, to our knowledge, the first report demonstrating an independent correlation of P-TKs with carcinoid diarrhea, a symptom that is customarily regarded as serotonin mediated.

  • Since their first description in 1882, malignant neoplasms of the appendix still remain rare.
  • Malignant carcinoid tumours are the most common accounting for 85% of all appendiceal neoplasms.
  • A retrospective review of all malignant carcinoid tumours diagnosed in our hospital between April 1994 and December 2003 was performed.
  • Nine patients were identified with classical carcinoid tumours (CCT); (M = 3 and F = 6, mean age: 43, range 14-81) and two patients with goblet-cell morphology (F = 2, age 46 and 76).
  • Other appendiceal pathologies were identified following hemicolectomy and oophorectomy.
  • From our experience and subsequent review of the literature, we recommend right hemicolectomy as the treatment of choice for malignant carcinoid tumours.
  • 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.

  • Malignant tumours of the appendix are rare.
  • They are usually carcinoid tumours that must be distinguished from extremely rare adenocarcinomas.
  • Metastatic mucinous adenocarcinomas of the appendix are only reported as case histories.
  • In clinical terms, the tumours usually manifest themselves as acute appendicitis, as ruptured appendicitis, as a tumour in the right lower abdominal quadrant or as a pelvic tumour, which are generally mistaken for an ovarian tumour with the same sonographic image.
  • Advanced primary adenocarcinomas of the appendix with ovarian metastases cannot be distinguished intraoperatively from a FIGO III ovarian carcinoma.
  • Surgical therapy of the isolated primary appendiceal carcinoma consists of a hemicolectomy--an appendectomy in favourable cases--and, in the case of a metastasised carcinoma, according to the guidelines for an advanced ovarian or colon carcinoma.

  • Goblet cell carcinoid is an uncommon primary tumor of the vermiform appendix, characterized by dual endocrine and glandular differentiation.
  • Whether goblet cell carcinoid represents a morphological variant of appendiceal classical carcinoid or a mucin-producing adenocarcinoma is a matter of conjecture.
  • Rare cases of goblet cell carcinoid with other concomitant appendiceal epithelial neoplasms have been documented.
  • In this report, we describe a rare case of combined appendiceal goblet cell carcinoid and mucinous cystadenoma, and discuss the possible histopathogenesis of this combination.

  • [Title] Appendectomy or right hemicolectomy in the treatment of appendiceal carcinoid tumors?
  • AIMS AND BACKGROUND: Carcinoids of the appendix continue to be of interest, despite their low incidence.
  • There is still considerable controversy surrounding these tumors, especially with regard to the role of right hemicolectomy in the surgical management.
  • The clinical data were reviewed for demographic details, tumor size, localization in the appendix, histological patterns and surgical procedures.
  • RESULTS: Seven patients (0.9% of all appendectomies) were reported to have carcinoid tumors of the appendix.
  • None suffered from the carcinoid syndrome.
  • The site of the tumor was the apex of the appendix in 4 cases, the body in 2 cases and the base in 1 case.
  • Mean tumor diameter was 8 mm (range, 5-29 mm); in 6 patients it was <2 cm.
  • Treatment was appendectomy in all cases; additional right hemicolectomy was necessary in one case because of a tumor of more than 2 cm with invasion of the mesoappendix and lymph nodes.
  • CONCLUSIONS: According to current guidelines, an appendectomy may be performed for small carcinoid tumors (<1 cm).
  • Reasons for more extensive surgery than appendectomy are tumor size >2 cm, lymphatic invasion, lymph node involvement, spread to the mesoappendix, tumor-positive resection margins, and cellular pleomorphism with a high mitotic index.
  • Tumor size is still considered the most important prognostic factor, with a presumed increase in the risk of metastasis for tumors greater than 2.0 cm.
  • The accepted treatment of such tumors is a right hemicolectomy.
  • However, there is no evidence demonstrating a survival benefit for right hemicolectomy over simple appendectomy in patients with carcinoids greater than 2.0 cm in diameter.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Goblet cell carcinoid tumors of the appendix: An overview.
  • Goblet cell carcinoid is an enigmatic and rare tumor involving the appendix almost exclusively.
  • 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.
  • The histologic hallmark of this entity is the presence of clusters of goblet cells in the lamina propria or submucosa stain for various neuroendocrine markers, though the intensity is often patchy.
  • 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.
  • There is some debate about the surgical approach for these tumors, and a summary of published series and recommendations are provided.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Malignancies of the appendix: beyond case series reports.
  • PURPOSE: A comprehensive analysis was performed for five histologic types of appendiceal tumors to compare incidence, clinicopathologic features, survival, and appropriateness of surgery.
  • METHODS: All patients diagnosed with mucinous adenocarcinoma (n = 951), adenocarcinoma (n = 646), carcinoid (n = 435), goblet (n = 369), and signet-ring cell (n = 113) in the Surveillance, Epidemiology, and End Results database (1973-2001) were analyzed.
  • The appropriateness of the operative procedure (i.e. , appendectomy vs. colectomy) was examined by tumor type and size.
  • RESULTS: Tumor incidence, patient demographics, survival outcomes, and appropriateness of surgery varied significantly among the different appendiceal tumor histologies.
  • The most common appendiceal tumors were mucinous.
  • With regard to patient demographics, carcinoids presented at an earlier mean age of 41 years and 71 percent were female (P < 0.001 for both).
  • Overall five-year survival was highest for carcinoid (83 percent) and lowest for signet ring (18 percent).
  • Although current guidelines specify that a right hemicolectomy (rather than an appendectomy) be performed for all noncarcinoid tumors and carcinoid tumors >2 cm, we found that 30 percent of noncarcinoids underwent appendectomy.
  • Similarly, 28 percent of carcinoids >2 cm under-went appendectomy, which is a lesser resection than is indicated.
  • CONCLUSIONS: This study provides a population-based analysis of epidemiology, tumor characteristics, survival, and quality of care for appendiceal carcinomas.
  • This characterization provides a novel description of the presentation and outcomes for malignancies of the appendix and highlights that a substantial number of patients with appendiceal tumors may not be receiving appropriate surgical resection.

  • [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.
  • The Ki-67 labeling index in classical carcinoids ranged from 0 to 5%.
  • This study shows that in addition to the morphological differences, GCC (CK7/CK20-positive) and classical carcinoid (CK7/CK20-negative) differ in their expression of CK7 and CK20.
  • 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] Carcinoid tumors of the appendix. Prognostic factors and evaluation of indications for right hemicolectomy.
  • BACKGROUND/AIMS: Carcinoid tumors of the appendix are thought to be the most common type of appendiceal neoplasms.
  • Although the vast majority of appendiceal carcinoids behave in a benign fashion, they are considered malignant because they all have the potential for invasion, metastasis and production of physiologically active substances.
  • Also, patients with tumor size more than 1cm underwent a Somatostatin Receptor Scintigraphy (Octreoscan).
  • RESULTS: The most common site for the tumors was the tip of the appendix (18/22).
  • In sixteen patients the tumor size was less than 1cm, in seven patients the tumor diameter was measured to be 1 to 2cm and in one patient the tumor was 3cm.
  • Most of our patients (16/22) underwent only an appendicectomy, while in the rest of them (in the patients with tumor size between 1-2cm and in the patient with invasion of mesoappendix) a right hemicolectomy was performed.
  • CONCLUSIONS: Carcinoid tumors of the appendix, in most cases, are found incidentally during appendicectomies, especially in young females and usually are less than 1cm in size, which is probably the reason of the absence of metastases in all cases.
  • Histological examination and size of the tumor are important factors that contribute to the selection of the surgical treatment and both must be estimated by the surgeons to make the final choice.

  • The immunoexpression of CK19 recently has been identified as a marker of poor prognosis in pancreatic endocrine tumors and hepatocellular carcinoma.
  • The purpose of this study was to explore CK19 and CD99 immunostaining in mucin-producing neuroendocrine (goblet cell) and classical carcinoids of the appendix.
  • Eighteen goblet cell carcinoids (GCCs) and 20 classic carcinoids were stained with CK19, CD99, and Ki-67, and these results were correlated with known pathological features of aggression: extent of invasion, mitoses, necrosis, and histological pattern.
  • All 18 GCCs were CK19 strongly positive, whereas 16/20 classic carcinoids were also CK19 positive.
  • Fourteen of 18 GCCs and 14/20 classic carcinoids were CD99 positive.
  • 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.

  • [Title] Carcinoid tumors.
  • Carcinoid tumors are rare, slow-growing neuroendocrine neoplasms that often are indolent and may not become clinically apparent until there has been metastatic spread or evidence of carcinoid syndrome.
  • Recent evidence has revealed that the overall incidence of carcinoid tumors has been steadily increasing, and although the disease was thought to be relatively benign, it is now considered one of increasing malignancy.
  • Carcinoid tumors derive from different embryonic divisions of the gut: foregut carcinoid tumors commonly originate in the lungs, bronchi, or stomach; midgut carcinoid tumors in the small intestine, appendix, or proximal large bowel; and hindgut carcinoid tumors in the distal colon or rectum.
  • Carcinoid syndrome, although rare, is most associated with midgut carcinoid tumors.
  • The diagnosis of a carcinoid tumor often is coincidental with surgery performed for another reason.
  • Treatment and prognosis are dependent on the location of the primary tumor and the degree and extent of metastasis at the time of diagnosis.

  • [Title] Endocrine tumors of the appendix: a pathologic review.
  • CONTEXT: Although rare, appendiceal endocrine tumors are the most common neoplasms of the appendix.
  • OBJECTIVE: To provide recent data that focus on the pathology of endocrine tumors of the appendix including classifications and guidelines for patient management.
  • CONCLUSIONS: Appendiceal endocrine tumors are separated into 2 main groups: classic endocrine tumors and goblet cell carcinoids.
  • Evaluation of their prognoses and risks of malignancy, according to these classifications, depends on several parameters including tumor size, proliferation rate, and infiltration of appendiceal wall and mesoappendix.
  • Most patients with classic endocrine tumors of the appendix have a favorable prognosis.
  • Indications for postappendectomy, complementary surgery, which are still controversial, especially for tumors between 1 and 2 cm, are presented and discussed.
  • In contrast, in patients presenting with a goblet cell carcinoid, a right hemicolectomy after the initial appendectomy is considered the standard surgical intervention.

  • [Title] Carcinoid tumors of the appendix. Our experience in a university hospital.
  • OBJECTIVE: To present our experience of carcinoid tumors of the appendix managed at a university teaching hospital.
  • The data of patients identified to have histological evidence of carcinoid tumors of the appendix were further reviewed for the demographic details, indications for surgery, surgical procedure, tumor localization in the appendix and size; concomitant appendicitis and further surgical procedures were considered.
  • RESULTS: During the study period, 1547 appendectomies were performed and, out of these, 9 (0.6%) cases were reported to have carcinoid tumors of the appendix.
  • Six carcinoid tumors were encountered at the appendiceal apex, 2 at the midportion, and one at the base with a mean diameter of 9.5 mm (range, 4-19 mm).
  • One patient had histologically confirmed residual tumor, which necessitated a right hemicolectomy 3 weeks later.
  • CONCLUSION: Carcinoid tumors of the appendix are extremely rare and invariably remain asymptomatic.
  • Simple appendectomy offers adequate relief while the need for further extensive surgery depends on tumor characteristics and dissemination.

  • 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.
  • We present three pediatric patients with bronchial carcinoid studied with somatostatin analogue scintigraphy (SSRS).
  • 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.
  • The third patient (12 years) came after a lobectomy (RUL) due to bronchial carcinoid.
  • In the subsequent control (3 months), a deposit of activity was observed in the middle third of the right hemithorax, after which a lobectomy was performed (RLL and ML) that showed small remains of neuroendocrine carcinoid.
  • CONCLUSION: The SSRS has demonstrated great utility in the diagnosis, follow-up and staging of pediatric patients, carriers of neuroendocrine carcinoid tumors.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] An unusual case of rectal carcinoid removed by transanal endoscopic microsurgery.
  • The name ''carcinoid'' was invented by Oberndorfer in 1907, when the nature of those histological entities was little understood.
  • Usually, they were found in various locations in the gastrointestinal (GI) apparatus (67%), most of them in the small intestine (25%), appendix (12%), and rectum (14%).The techniques used for their removal are various.
  • The authors present here a case of rectal carcinoid removed using the transanal endoscopic microsurgery technique, and referred to the diagnosis and treatment of this uncommon tumor.
  • Complete blood count (CBC) and laboratory data as tumor markers and urinary 5-hydroxyindoleacetic acid (5-HIAA) showed no abnormalities, while urinary vanilmandelic acid level was elevate (18 mg/24 h).
  • Histochemically the tumor cells were cytocheratins +/-, chromogranin positive, synaptophysine positive, CD56 positive and Growth Index MIB1-Ki67 which was almost zero.
  • The use of Transanal Endoscopic Microsurgery (TEM) as a safe and feasible technique for exciding rectal tumors can be easily understood, for the excellent view and precise dissection.
  • A full diagnostic course and an immunohistochemistry are mandatory for precise diagnosis of rectal carcinoid.
  • Careful attention must be paid to these tumors because of their unexpected behaviour.

  • 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.
  • In 4-10% of patients typical symptoms of carcinoid syndrome are present.
  • 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.
  • This is treatment of choice in carcinoid crisis.
  • Interferon alfa could be applied because of the same indications as somatostatin analogs, except for carcinoid crisis.
  • Chemotherapy is less successful in disseminated or locally advanced intestinal neuroendocrine tumors, so radioisotope therapy should be considered in each case of unresectable tumor.

66. 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.
  • A literature search of the PubMed database was then performed using the medical search headings; appendix, tumour, neoplasm and malignancy.
  • Eleven patients were found to have carcinoid-type tumours, eight patients with adenocarcinomas and three patients with lymphomas.
  • Other appendiceal pathologies were identified after appendicectomies, hemicolectomy and oophorectomy.
  • Patients with classical carcinoid tumours (CCT) had better outcomes than patients with the goblet cell carcinoid, adenocarcinoma and lymphoma.
  • 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.

  • Carcinoid tumors originate from the argentofile cells found at the bottom of the crypt of Lieberkuhn.
  • In spite of their slow growth and comparatively better prognosis, the carcinoid are malignant tumors, which effective treatment is their surgical resection.
  • We present 10 patients with carcinoid of the gastrointestinal tract (GIT)--3 from small intestine, 3 from large intestine, 2 from appendix, I from rectum and 1 from stomach, operated at our clinic for a 6 year period of time.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [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.

  • BACKGROUND: Carcinoid tumor (CT) is an unusual neoplasm observed in several locations and associated with the production of vasoactive substances and occasionally with carcinoid syndrome (flushing, diarrhea, wheezing).
  • Eight had CT of the appendix, of which 4 showed the typical clinical presentation of acute appendicitis.
  • Seven of these tumors were localized at the tip of the appendix and measured 2 cm or less.
  • In one patient, the tumor was located at the cecum and measured 3.5 cm.
  • In this patient, reoperation with ileocecal resection was performed.
  • None of the patients showed symptoms of carcinoid syndrome.
  • CONCLUSIONS: Typical symptoms of acute appendicitis were not observed in half of patients with CT of the appendix.
  • CT associated with carcinoid syndrome is exceptional in pediatric patients.
  • In most CT of the appendix, simple appendicectomy was associated with an excellent prognosis.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Lipid-rich variant of appendiceal well-differentiated endocrine tumor (carcinoid).
  • Well-differentiated endocrine tumors (WDETs) of the appendix show characteristic morphologic features, including proliferation of cells with finely granulated eosinophilic cytoplasm.
  • We studied 13 appendiceal WDETs composed of clear cells, which showed an immunophenotype identical to that of conventional appendiceal WDETs.
  • Patient survival was excellent and equal to that of conventional appendiceal WDETs.
  • These neoplasms, which represent a lipid-rich variant of appendiceal WDETs, do not have different relevant clinical implications compared with conventional WDETs, but it is important to know of their existence for the differential diagnosis with more aggressive neoplasms, including goblet cell carcinoids and appendiceal metastases from clear cell carcinomas.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [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.

  • [Title] Laparoscopic appendectomy after conservative management of appendix mass.
  • The purpose of this study was to demonstrate the safety and efficacy of laparoscopic appendicectomy following non-operative management of appendix mass in children.
  • Medical records of 103 consecutive patients (61 males, 42 females) who underwent non-operative treatment of appendix mass followed by laparoscopic elective appendicectomy were examined.
  • Ten (9.7%) did not respond to initial treatment and developed appendix abscess requiring drainage.
  • Histological examination revealed fibrosed or resolving appendicitis in 52, acute or subacute appendicitis in 24, carcinoid tumour in two and normal appendix in 19.
  • Laparoscopic elective appendicectomy is a safe and effective method of treatment following conservative treatment of appendix mass.
  • Not only does it make the dissection and resection of the appendix easier but it also has the added advantage of performing adhesiolysis.

  • [Title] The significance of occult carcinoids in the era of laparoscopic appendectomies.
  • BACKGROUND: We present data acquired in our institution about the incidence of incidental appendiceal carcinoids over a period of 16 years.
  • The possibility of occult carcinoids raises the question of appendectomy of a noninflamed appendix during diagnostic laparoscopy for suspected appendicitis.
  • Outcome measures were the incidence of incidental carcinoids of the appendix found during appendectomies and whether the introduction of laparoscopic appendectomy should alter the surgical management of a normal-appearing appendix.
  • RESULTS: A total of 20 carcinoid appendices were resected by open surgery and 17 by laparoscopy.
  • The diagnosis of a carcinoid tumor was not suspected in any patient before the operation, nor was a tumor identified at the time of the operation.
  • In 6 (16%) patients the appendix appeared normal at the time of the operation.
  • CONCLUSIONS: It has long been the standard of care to remove any appendix found in laparotomy for suspected appendicitis, but it is not clear what should be done during laparoscopy for suspected appendicitis when the appendix appears normal.
  • Our data confirm the presence of occult carcinoids in normal-appearing appendices.

  • [Title] Ovarian metastases of appendiceal tumors with goblet cell carcinoidlike and signet ring cell patterns: a report of 30 cases.
  • Synchronous and metachronous ovarian and appendiceal mucinous tumors are often the subject of diagnostic consultations in gynecologic pathology practices to address whether the tumors are independent neoplasms or related as primary and metastasis.
  • The ovarian tumors were bilateral in 25 of 28 cases with data on both ovaries and were typically large (mean/median: 14 cm, range: 4.5 to 24.0 cm).
  • The appendices were often firm or thickened but usually did not have a discrete measurable tumor and were not notably enlarged; microscopically, transmural invasion was present in all of them.
  • The ovarian and appendiceal tumors exhibited a variety of patterns of differentiation, including signet ring cell and glandular, with all displaying some goblet cell carcinoidlike patterns (nests, islands, cords, or cryptlike tubules with goblet cells); teratomatous elements were not identified in any ovarian tumors.
  • Chromogranin was expressed in 7 of 19 ovarian tumors (mean/median: 6.3%/0%; range: 0% to 20%) and synaptophysin was expressed in 4 of 18 of these (mean/median: 7.8%/0%; range: 0% to 90%).
  • Chromogranin was expressed in 6 of 16 appendiceal tumors (mean/median: 11.9%/0%; range: 0% to 70%) and synaptophysin was expressed in 6 of 15 of these (mean/median: 16.7%/0%; range: 0% to 90%).
  • The clinicopathologic features of these ovarian tumors indicate they should be labeled as metastatic appendiceal adenocarcinomas rather than as goblet cell carcinoid tumors both to reflect their behavior and help distinguish them from the rare true primary ovarian goblet cell carcinoid tumors.
  • As the ovarian tumors have appreciable components of signet ring cells they qualify as Krukenberg tumors.
  • In cases in which the primary tumor is not already evident, their "goblet cell carcinoidlike" patterns should direct attention to the appendix as a possible source.

  • [Title] From the archives of the AFIP: Gastrointestinal carcinoids: imaging features with clinicopathologic comparison.
  • Gastrointestinal carcinoids are well-differentiated endocrine neoplasms that belong to a diverse group of tumors that arise from cells of the diffuse endocrine system.
  • A wide variety of specialized endocrine cells that populate the gastrointestinal mucosa and submucosa give rise to carcinoids.
  • Consequently, carcinoids may occur throughout the gastrointestinal tract and produce a variety of hormones and protein products that are associated with specific clinical symptoms.
  • Biologic behavior of carcinoids varies by site and cell type, but all gastrointestinal carcinoids are considered to have malignant potential.
  • Metastatic carcinoids may produce carcinoid syndrome.
  • The small intestine is the most common location for gastrointestinal carcinoids.
  • Most small intestinal carcinoids arise from enterochromaffin cells of the distal ileum that produce serotonin.
  • Small intestinal carcinoids often have an aggressive biologic behavior and, as such, patients frequently have metastases to regional lymph nodes and the liver at initial presentation.
  • Pathologic and radiologic manifestations of serotonin-producing small intestinal carcinoids are related to local and regional effects of serotonin and its metabolites.
  • In contrast, carcinoids of the appendix and rectum are commonly discovered incidentally as small lesions that are unassociated with clinical evidence of hormone production and have a more indolent clinical course.
  • Carcinoids of the stomach, duodenum, and colon are uncommon but have distinctive clinical, pathologic, and radiologic appearances.
  • Knowledge of the diverse clinical, pathologic, and radiologic spectrum of gastrointestinal carcinoids is important in the imaging and management of patients with suspected carcinoids or focal gastrointestinal masses.

  • [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.
  • CONCLUSION: Although the majority of carcinoid tumors arise from the appendix, these tumors can also occur in other primary sites.

  • [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.
  • Although its malignant potential remains unclear, adenocarcinoids seem to be biologically more aggressive than conventional carcinoids.
  • 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.
  • 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.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Granin-derived peptides as diagnostic and prognostic markers for endocrine tumors.
  • Chromogranin A-like immunoreactivity (CgA-LI) has been, and remains, the most widely used diagnostic and prognostic marker for endocrine tumors.
  • Additionally, certain endocrine tumors, such as rectal carcinoids, do not express the CgA gene so that there is a need for additional markers to complement CgA measurements.
  • Plasma concentrations of the CgA-derived peptide, pancreastatin, measured with antisera of defined regional specificity, have a prognostic value in patients with metastatic midgut carcinoid tumors receiving somatostatin analog therapy or hepatic artery chemoembolization.
  • Other CgA-derived peptides with potential as tumor markers are vasostatin-1, WE-14, catestatin, GE-25, and EL-35 but their value has yet to be fully assessed.
  • Circulating concentrations of chromogranin B-like immunoreactivity (CgB-LI) are not elevated in non-neoplastic diseases and measurements of CCB, the COOH-terminal fragment of CgB, may be useful as a biochemical marker for neuroendocrine differentiation in lung tumors.
  • Antisera to the secretogranin II-derived peptide, secretoneurin detects carcinoid tumors of the appendix with greater frequency than antisera to CgA and are of value in identifying therapy-resistant carcinoma of the prostate (clinical stage D3).
  • Measurement of concentrations of a second secretogranin II-derived peptide, EM-66 in tumor tissue has been used to differentiate between benign and malignant pheochromocytoma.
  • These examples point to a limited although potentially valuable role for granin-derived peptides as tumor markers.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • METHODS: We reviewed cases of 42 patients who underwent total laparoscopic hysterectomy or laparoscopic-assisted vaginal hysterectomy followed by appendectomy, performed by applying a stapler and removing the appendix transvaginally.
  • By using a small-diameter laparoscope, the appendix was mobilized, especially in patients with adhesions, endometriosis, or retrocecal appendix, to facilitate transvaginal access with the stapler.
  • Appendiceal pathology included serosal adhesions (14), fibrous obliteration of the lumen (12), endometriosis (4), serositis (2), and carcinoid tumor (1), among others.

  • [Title] Carcinoid tumors of the appendix in children: experience from a tertiary center in northern Greece.
  • BACKGROUND AND OBJECTIVE: Carcinoid tumors of the appendix are rare in childhood and usually have a benign clinical course.
  • The aim of the study was to report the frequency, clinical presentation, tumor characteristics, and outcome of children with appendiceal carcinoid treated in a pediatric oncology department.
  • Demographics, clinical presentation, tumor characteristics, and follow-up results were recorded.
  • RESULTS: Among 839 admissions, 19 patients (9 boys) with appendiceal carcinoid were identified during the study period.
  • The mean tumor diameter was 4.55 (± 3.45) mm (range 1-15 mm).
  • In 18 children tumor size was ≤ 10 mm and did not infiltrate surrounding tissues.
  • In 1 patient the size was 15 mm and a microscopic rupture of the appendix with infiltration of the surrounding fat was present.
  • All of the tumors were located at the tip of the appendix and were of the classic histological type.
  • CONCLUSIONS: Carcinoid tumors of the appendix in children are rare.

  • [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).
  • There was equivalent survival between patients with carcinoid and without.
  • 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.

  • [Title] Carcinoid tumors of the gastrointestinal tract: trends in incidence in England since 1971.
  • OBJECTIVES: The epidemiology of gastrointestinal neuroendocrine tumors (GI-NETs) is poorly understood.
  • Recent analyses have suggested changes in the incidence and distribution of such tumors, but have generally used data sets containing small patient numbers.
  • The anatomic distribution of tumors in the latest period analyzed was stomach 12%, small intestine 29%, appendix 38%, colon 13%, and rectum 8%.
  • The largest absolute increase in incidence was seen in the appendix (from 0.03 to 0.41 in men; from 0.05 to 0.59 in women).
  • Sex-specific incidence rates for gastric, colonic, and rectal NETs are similar, whereas appendiceal lesions were more common in females, and small intestinal tumors in men.
  • In view of the magnitude of these changes, particularly for gastric tumors, further studies to examine the underlying etiology of these changes are urgently indicated.

  • [Title] Extrapulmonary small cell carcinomas express K homology domain containing protein overexpressed in cancer, but carcinoid tumors do not.
  • A number of malignancies, including high-grade neuroendocrine carcinomas of the lung, have been reported to express K homology domain containing protein overexpressed in cancer (KOC), a member of the insulin-like growth factor messenger RNA-binding protein (IMP) family also known as L523S and IMP3.
  • KOC acts to promote tumor cell proliferation by enhancing insulin-like growth factor-II protein expression.
  • This study aimed to examine KOC expression pattern in extrapulmonary neuroendocrine tumors.
  • Seventy-five extrapulmonary neuroendocrine tumors that were surgically resected or had undergone biopsy, including 53 small cell carcinomas (uterine cervix, 21; bladder, 10; colorectum, 13; prostate, 7; stomach, 1; and esophagus, 1) and 22 carcinoid tumors (colorectum, 10; appendix, 5; ileum, 4; duodenum, 2; and stomach, 1), were immunohistochemically studied using a monoclonal antibody against KOC.
  • Our results demonstrated that 47 small cell carcinomas (89%) showed moderate to strong positive staining for KOC, with 25 cases (53%) showing positivity in more than 90% of tumor cells and 22 cases (47%) in 40% to 80% of tumor cells.
  • Three cases showed weak staining in 5% to 10% of the tumor cells.
  • No KOC immunostaining was detected in 22 carcinoid tumors.
  • In addition, immunohistochemical detection of KOC expression may serve as a useful diagnostic tool in the distinction between small cell carcinoma and carcinoid tumor, particularly when the diagnostic material is a small biopsy with crushing artifact.

  • [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%.
  • Liver metastases from jejunal and ileal carcinoids are generally hypervascular.
  • 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] 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.
  • 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.
  • 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.

  • [Title] Pathologic classification and clinical behavior of the spectrum of goblet cell carcinoid tumors of the appendix.
  • Appendiceal tumors exhibiting both neuroendocrine and glandular differentiation are uncommon and have caused difficulty in pathologic classification, prediction of prognosis, and clinical management.
  • Previously, such lesions have been variously designated as adenocarcinoid, goblet cell carcinoid (GCC), and mixed adenocarcinoma carcinoid.
  • 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.
  • 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.
