  • [Title] Villous adenoma: a rare tumor of vaginal vault.
  • Villous adenomas are extremely rare tumors in the vagina and are indistinguishable from their colonic counterparts.
  • The significance of this lesion lies in the fact that it has to be distinguished from metastatic adenocarcinoma from other sites.
  • We present a case of villous adenoma of vaginal vault, a rare site of presentation in a 30-year-old female.

MedlinePlus Health Information. consumer health - Colorectal Cancer.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Computed tomographic colonography, also known as virtual colonoscopy, is an innovative and secure technology which is revolutionizing the diagnosis of colon and rectum neoplasias.
  • The histological analysis of resected lesions revealed 12 tubular adenomas, 6 hyperplastic polyps and 1 colonic tubulo-villous adenoma with an adenocarcinoma focus.
  • In this study, computed tomographic colonography was performed without complications and a complete and safe colorectal evaluation was possible in all acromegalic patients.
  • Moreover, computed tomographic colonography presented good sensitivity, specificity and accuracy for the identification of acromegalic patients with polyps of any size and better results in the diagnosis of large polyps, when they were compared to small polypoid lesions.

NCI CPTC Antibody Characterization Program. NCI CPTC Antibody Characterization Program .

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Since inflammation is associated with cancer progression and angiogenesis, we investigated expression of cytokines like IL-6 and other mediators that play a key role in the innate immune system, in particular toll like receptor 4 (TLR4), in the microenvironment of lesions from different stages of colon disease progression, from ulcerative colitis to adenoma and adenocarcinoma to find useful markers.
  • 116 Archival tissue samples from patients with different stages of colorectal disease: 13 cases of ulcerative colitis (UC), 34 tubular or tubulo-villous adenomas (AD), and 53 infiltrating adenocarcinomas.
  • TLR-4 and IL6 expression in the tumor microenvironment were associated with adenocarcinoma in human samples and in the murine model.
  • We found that adenocarcinoma patients (pT1-4) with higher TLR-4 expression in stromal compartment had a significantly increased risk in disease progression.
  • In those patients with a diagnosis of pT3 (33 cases) colon cancer, those with very high levels of TLR-4 in the tumor stroma relapsed significantly earlier than those with lower expression levels.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Immunohistochemical expression of prostatic antigens in adenocarcinoma and villous adenoma of the urinary bladder.
  • Adenocarcinomas of the bladder are rare, with the diagnosis dependent on exclusion of secondary involvement by direct extension or metastatic spread from other sites.
  • The recent description of an unusual form of urothelial-type mucinous prostatic adenocarcinoma raises a novel differential diagnosis between adenocarcinomas of the prostate and bladder, and investigation into the utility of classic prostatic immunohistochemical antigens in bladder adenocarcinoma is warranted.
  • We identified 37 primary infiltrating adenocarcinomas of the bladder, which included signet ring cell carcinomas (n=11), urachal adenocarcinomas (n=5), and enteric adenocarcinoma (n=21).
  • Also included for comparison were 3 cases, each of bladder villous adenomas and bladder adenocarcinoma in situ.
  • Of the 37 adenocarcinomas, all were negative for PSA and PSAP (0/37; 0%).
  • In contrast, a minority of bladder adenocarcinomas was labeled with the prostate antigens P501S and PSMA.
  • P501S showed moderate diffuse cytoplasmic staining in 4/37 cases (11%), including 3 enteric-type adenocarcinomas and 1 mucinous adenocarcinoma.
  • Additionally, 1 case of adenocarcinoma in situ demonstrated diffuse cytoplasmic staining for P501S.
  • The granular perinuclear staining pattern of P501S typically seen in prostatic adenocarcinoma was absent in all cases of bladder adenocarcinoma.
  • PSMA showed diffuse cytoplasmic staining in 4/37 (11%) infiltrating adenocarcinomas (including 1 signet ring carcinoma and 3 enteric-type adenocarcinomas), and in 1 case of adenocarcinoma in situ.
  • Membranous PSMA staining was evident in an additional 3 tumors, 1 urachal mucinous adenocarcinoma, 1 nonurachal mucinous and signet ring cell adenocarcinoma, and 1 nonurachal villous adenoma.
  • In conclusion, although all cases of bladder adenocarcinoma examined were negative for PSA and PSAP, the surprising finding that a subset of invasive and in situ adenocarcinomas of the bladder demonstrated immunoreactivity for P501S and PSMA should warrant caution when using these markers in differentiating prostatic from bladder adenocarcinomas.
  • The lack of granular perinuclear staining for P501S and the absence of membranous PSMA staining both favor a bladder adenocarcinoma, although rare cases of villous adenoma and adenocarcinoma did show PSMA membranous staining indistinguishable from that seen in prostate cancer.
  • Although the novel antigens P501S and PSMA are fairly specific and more sensitive in the differential diagnosis of prostate and urothelial carcinoma, care must be taken when adenocarcinomas of the bladder are considered within this differential diagnosis.

  • A frozen-section examination of these particles revealed villous adenoma.
  • The frozen-section examination of the resected material also revealed a villous adenoma.
  • The histological examination revealed a villous adenoma arising from the biliary epithelium and some adenocarcinoma foci.
  • This case shows the importance of surgeons to keep in mind the fact that frozen examinations may sometimes miss a malignancy and they therefore cannot be relied upon to rule out malignancy in villous adenoma of the ampullary bile duct.

  • [Title] [Expression of minichromosome maintenance protein 2 in colonic adenocarcinoma, adenoma and normal colonic mucosa and its clinical significance].
  • OBJECTIVE: To investigate the expression differences of minichromosome maintenance 2 (MCM2) mRNA and protein among colon adenocarcinoma, colon adenoma and normal mucosa, and among different clinicopathological types of adenomas.
  • METHODS: Fifty specimens, including 33 colonic adenomas, 12 colonic adenocarcinomas and 5 normal colonic mucosa were selected.
  • Expression differences of MCM2 mRNA among the colonic adenocarcinoma, adenoma and normal colonic mucosa were evaluated by REST-XL software.
  • RESULTS: The expression of MCM2 was observed in the basal third to half of the colonic crypts in normal mucosa, while throughout the epithelium in the colonic adenocarcinomas and adenomas.
  • However, the expression of MCM2 mRNA in the adenocarcinomas was significantly higher than that in the adenomas(P=0.001).
  • The MCM2 mRNA expression was elevated in the adenoma with villous type, in the conditions of high-grade dysplasia, larger size, sessile morphology and in patients of older ages, but the difference was not significant by REST-XL (P>0.05).
  • CONCLUSION: The difference of MCM2 expression between the adenoma and the adenocarcinoma indicates its potential value in the early diagnosis of colonic cancer.

  • [Title] A case of colorectal carcinoma in adenoma analyzed by a cDNA array.
  • Microscopically, the large tumor consisted of a well-differentiated adenocarcinoma with a tubulovillous adenoma (TVA) component (carcinoma in adenoma).
  • Some carcinoma (CA) cells had invaded the submucosal layer, but the lymph nodes were negative for malignancy.
  • K-ras mutation was detected in both CA and TVA lesions of the carcinoma in adenoma.
  • To clarify relevant alterations of gene expression associated with adenoma-carcinoma progression, the gene expression profiles of these tumor tissues were analyzed by a cDNA array.
  • RESULTS: Although the gene expression profiles were similar, insulin-like growth factor-II (IGF-II) was expressed most differentially in CA and TVA tissues.
  • The results were further substantiated by comparison of the gene expression profiles of CA and TVA lesions of the carcinoma in adenoma.
  • CONCLUSION: The results suggest that overexpression of IGF-II played an important role in the progression of adenoma to carcinoma in this patient.

  • [Title] Primary mucin-producing urothelial-type adenocarcinoma of prostate: report of 15 cases.
  • Prostatic urothelial-type adenocarcinoma arises through a process of glandular metaplasia of the prostatic urethral urothelium and subsequent in situ adenocarcinoma sometimes associated with villous adenoma.
  • These prostatic adenocarcinomas are analogous to nonurachal adenocarcinomas arising in the bladder from cystitis glandularis.
  • Only 2 cases of urothelial-type adenocarcinoma from an institution other than our own have been previously described.
  • The distinction between adenocarcinoma from another organ secondarily involving the prostate, usual adenocarcinoma of the prostate, and prostatic urothelial-type adenocarcinoma can present a significant diagnostic challenge and has significant therapeutic implications.
  • Fifteen cases of prostatic urothelial-type adenocarcinoma were retrieved from the consult files of one of the authors.
  • Mean patient age at diagnosis was 72 years (range 58 to 93 y).
  • In 8/15 (53%) cases, glandular metaplasia of the prostatic urethra and contiguous transition to adenocarcinoma were identified.
  • Multiple histologic patterns were observed including dissection of the stroma by mucin pools 15/15 (100%), villous features 7/15 (47%), necrosis 2/15 (13.3%), signet ring cells 3/15 (20%), perineural invasion 1/15 (6.7%), focal squamous differentiation 1/15 (6.7%), and a granulomatous inflammatory response 1/15 (6.7%).
  • Prostatic urothelial-type adenocarcinoma is a rare aggressive cancer arising in the prostate.
  • The differential diagnosis includes conventional prostatic mucinous adenocarcinoma and secondary infiltration from a colonic or bladder adenocarcinoma.
  • Immunohistochemistry for prostate specific antigen, prostate specific acid phosphatase, and high molecular weight cytokeratin along with morphology can help rule out conventional prostate carcinoma. beta-catenin, CDX2, and clinical studies are needed to rule out colonic adenocarcinoma.
  • As prostatic urothelial-type adenocarcinoma is entirely analogous to bladder adenocarcinoma in both, its morphology and immunophenotype, only clinical studies or in some cases pathologic examination of the cystoprostatectomy specimen can exclude infiltration from a primary bladder adenocarcinoma.

NCI CPTC Antibody Characterization Program. NCI CPTC Antibody Characterization Program .

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • OBJECTIVE: To study the clinicopathologic features and proliferative status of colorectal hyperplastic polyp (HP), sessile serrated adenoma (SSA) and traditional serrated adenoma (TSA).
  • RESULTS: On the basis of morphologic examination, 60 cases were classified as HP, 20 cases as TSA, 11 cases as SSA, 7 cases as mixed HP/SSA/TSA, and 6 cases as mixed serrated polyp/adenoma and tubular adenoma.
  • The number and distribution of Ki-67 positive cells in SSA were similar to those in TSA but were significantly different from those in tubular adenoma and adenocarcinoma (chi2=34.601, P=0.000; chi2=63.077, P=0.000, respectively).
  • CONCLUSIONS: HP, SSA and TSA have their morphologic characteristics, with some overlapping features noted.
  • Diagnosis of SSA relies mostly on architectural rather than cytologic features.
  • In general, the proliferative index is lower in serrated adenoma (TSA or SSA) than in tubular adenoma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • The objective of this study is to measure the risk of colorectal cancer and adenoma with screening colonoscopy and its cost effectiveness.
  • Among those 11,808 screening colonoscopies performed, advance neoplasm (adenocarcinoma) was detected in 272 (2.3%) patients; age 50 to 90, with mean age of 64-years-old.
  • Fourteen per cent had hyperplastic polyps, 15 per cent had tubular adenoma, and 8.6 per cent villous adenoma.
  • Adenoma with high grade dysplasia was found in 6.6 per cent, and 5.5 per cent had nonadenomatous lesions.
  • Rate of adenocarcinoma from 2000 to 2006 was (24/470, 29/520, 33/891, 37/961, 46/2889, 49/2977, and 54/3100).

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • BACKGROUND: Although non-AIDS defining malignancies are rapidly increasing as HIV-infected subjects live longer, little is know about the results of screening for colonic neoplasms (adenomatous polyps and adenocarcinomas) in this population.
  • Advanced neoplasms were defined as adenomas >or=10 mm or any adenoma, regardless of size, with villous histology, high-grade dysplasia, or adenocarcinoma.
  • Among patients with colorectal adenocarcinoma, HIV-infected subjects were significantly younger (52.4 (SD 1.3) vs 60.3 (SD 4.0) years, p = 0.002) and were more likely to have advanced cancers (stage III or IV) than control subjects (60.0% vs 16.7%, p = 0.24).
  • CONCLUSIONS: HIV-infected subjects have a higher prevalence of colonic neoplasms, and adenocarcinomas develop at a younger age and are more advanced than in uninfected subjects.

  • BACKGROUND: Intraductal papillary-mucinous neoplasm (IPMN) is an intraductal tumor in which the mucin-producing epithelium shows proliferated papillary and a wide variety of pathological changes ranging from hyperplasia to adenocarcinoma.
  • We carried out the differential diagnosis of benign lesion to malignant lesion.
  • METHODS: Between April 2003 and May 2009, PPS using a small-diameter videoscope by means of NBI was carried out on 21 hospitalized patients with IPMN (10 cases of adenocarcinoma, 11 cases of adenoma or hyperplasia; 14 males and seven females, with a mean age of 69.4 years).
  • RESULTS: Fifteen focal lesions of the 16 cases in the head of the pancreas (93.7%) and four focal lesions of the five cases in the pancreatic body (80%) were observable, whereas two lesions (adenocarcinoma in the pancreatic body, and adenoma in the uncus of pancreas) were not observable.
  • Endoscopically, seven cases were classified as villous type and two cases as vegetative type, and nine cases were diagnosed as adenocarcinoma.
  • Ten cases with sessile type or semipedunculated type were diagnosed as adenoma or hyperplasia.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • METHODS: The study consisted of a retrospective review of all the medical records of patients who underwent a colonoscopy for the first time during the calendar year 2005 and had a pathologic diagnosis of HP, tubular adenoma (TA), tubulovillous adenoma (TVA), villous adenoma (VA) and/or colon adenocarcinoma at the VA Caribbean Healthcare System.
  • Histologic evaluation of lesions revealed: 121 patients who had HP, 331 with TA, 33 with TVA, 12 with VA, 13 with serrated adenomas and 61 patients had adenocarcinoma.
  • Univariate analysis revealed that patients with HP appeared to have a lower likelihood of having TA (p < 0.001), adenocarcinoma (p = 0.002), and CRN in general (P < 0.001) as compared to patients without HP.
  • Multivariate analysis with logistic regression revealed that patients with HP had a significantly lower likelihood of having TA (adjusted OR = 0.21; 95% CI 0.12-0.37), and adenocarcinoma (adjusted OR = 0.33; 95% CI 0.15-0.73) compared to patients without HP.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Preoperative biopsies (obtained in all patients) showed 18 adenomas, four adenomas with dysplasia, five adenomas with atypia, one adenoma with dysplasia and focal adenocarcinoma, and two tumors seen on endoscopy, whose biopsies showed only duodenal mucosa.
  • The final pathologic diagnosis was 23 villous adenomas, six adenocarcinomas, and one paraganglioma.
  • On preoperative biopsies, all patients who had high-grade dysplasia and one of five patients with atypia turned out to have invasive adenocarcinoma when the entire specimen was examined postoperatively.
  • Two (33%) adenocarcinomas recurred at a mean of 4 years; both had negative margins at the initial resection.
  • Among the 23 adenomas, three (13%) recurred (all as adenomas) at a mean of 3.2 years; in only one of these cases was the margin positive at the time of resection.
  • Ampullary adenomas can be resected locally with good results, but the recurrence rate was 13%, so endoscopic surveillance is indicated postoperatively.
  • No adenomas recurred as carcinomas, suggesting that local resection is appropriate for these tumors in the absence of dysplasia or atypia on preoperative biopsies.
