  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Tubulovillous adenoma of anal canal: a case report.
  • Tumors arising from the anal canal are usually of epithelial origin and are mostly squamous cell carcinoma or basal cell carcinoma.
  • We present a case of benign anal adenomas arising from the anus, an extremely rare diagnosis.
  • The squamocolumnar junction was visible at the edges of the lesion confirming the anal origin of the tumor.
  • We believe the tubulovillus adenoma arose from either an anal gland or its duct that opens into the anus.
  • Although seen rarely, it is important to recognize and treat these tumors at an early stage because of their potential to transform into adenocarcinoma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Synchronous rectal adenocarcinoma and anal canal adenocarcinoma.
  • It is difficult to distinguish a rectal carcinoma with anal metastases from coexistent synchronous anorectal carcinomas.
  • The therapeutic strategy for rectal and anal carcinoma is so different that it should be clearly identified.
  • Here, we report on the case of a 63-year-old man who presented with an upper-third rectal adenocarcinoma.
  • Five months after resection, he developed an adenocarcinoma in the anal canal.
  • For this reason, we believe the present case had synchronous adenocarcinomas arising from anal canal and the rectum separately.
  • It is very important to differentiate the anorectal lesions pathologically because of the impact on the therapeutic options available, especially for the lesion arising in the anal canal.

MedlinePlus Health Information. consumer health - Anal Cancer.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Anal canal adenocarcinoma with MUC5AC expression suggestive of anal gland origin.
  • Anal canal adenocarcinomas arising in the anal ducts or glands are very rare neoplasms, and few useful immunohistochemical markers of these carcinomas are known to date.
  • A 57-year-old man presented with anal bleeding, difficulty of defecation, and anal pain.
  • Macroscopic findings of the surgically resected material showed circular stenosis of the anal canal.
  • Microscopically, the proliferation of adenocarcinoma cells with mucin production was observed in the submucosal and muscular layers.
  • Immunohistochemically, normal rectal-type mucosa and normal anal ducts/glands showed the patterns of cytokeratin 7 (CK7)(-)/CK19(+, focal)/MUC5AC(-) and CK7(+, diffuse)/CK19(+, diffuse)/MUC5AC(+, focal), respectively, and neoplastic cells showed the pattern of CK7(+, diffuse)/CK19(+, diffuse)/MUC5AC(+, focal).
  • Finally, our preliminary report suggests that the immunohistochemical combination of CK7, CK19, and MUC5AC may be an available marker for adenocarcinoma of anal ducts/glands origin.

  • [Title] Primary adenocarcinoma of the anus: a 22-year SEER population database analysis.
  • : e15072 Background: Most anal canal cancers consist of squamous cell carcinoma (SCCA).
  • Adenocarcinoma (AdenoCa) is rare and accounts for approximately 10% of anal cancers.
  • METHODS: The search of the SEER database revealed 1,008 pts who had pathologically confirmed anal cancers with either SCCA or AdenoCa.
  • All pts had single diagnosis of anal cancer with localized disease without nodal involvement.
  • On the other hand, among the AdenoCa subset, pts who had APR had better 10-yr OS than RT pts (53.8% vs. 0%, p=0.03) Conclusions: For localized anal SCCA, RT yielded equivalent overall survival as compared to APR.
  • On the other hand, pts with localized anal adenoCa appeared to do worse when APR was omitted.
  • Omission of APR in pts with anal canal adenoCa should be cautiously weighed.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Basaloid squamous carcinoma of the anal canal with an adenoid cystic pattern: histologic and immunohistochemical reappraisal of an unusual variant.
  • Two cases of a distinctive variety of basaloid squamous carcinoma (BSC) of the anal canal are described.
  • Accompanying dysplasia of the overlying squamous mucosa was absent.
  • BSC of the anal canal with an adenoid cystic pattern is an infrequently encountered and reported variant, although it is seen more often in the aerodigestive tract.

  • Poorly differentiated malignancies affecting the anal canal are uncommon but pose diagnostic difficulties because of the wide range of normal cell types that may occur within a limited anatomical region.
  • The range of lesions that may present as poorly differentiated tumours includes squamous cell carcinoma, adenocarcinoma, small and large cell neuroendocrine carcinoma, neuroendocrine carcinoma expressing epithelial cytokeratins and other patterns of mixed differentiation, undifferentiated carcinoma, malignant melanoma, lymphoma and secondary tumours.
  • This review discusses the differential diagnosis of these neoplasms with the aid of short illustrative case studies.

  • A 70-year-old man with a history of colon polyps was found to have a semipedunculated polyp in the anal canal.
  • Histological examination of biopsy specimens revealed well-differentiated adenocarcinoma of the anal canal.
  • Pathological examination of the anal canal carcinoma revealed submucosally invasive well-differentiated adenocarcinoma with a positive distal surgical margin.
  • Pathological examination revealed continuance within the epidermis between the anal canal adenocarcinoma and Paget's cells in the perianal skin lesion.
  • Thus, we concluded that the perianal skin lesion was Pagetoid spread of anal canal adenocarcinoma.
  • This report shows that the perianal skin should be examined carefully in patients with anal canal carcinoma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Immunohistochemical staining for p63 is useful in the diagnosis of anal squamous cell carcinomas.
  • Anal canal carcinomas account for between 1% and 2% of all gastrointestinal carcinomas in the United States.
  • By far, the most common carcinoma in this site is squamous cell carcinoma, but the differential diagnosis typically includes poorly differentiated adenocarcinoma and well-differentiated neuroendocrine carcinoma or carcinoid tumor.
  • However, accurate diagnosis is imperative, because the treatment differs between squamous carcinoma (chemoradiation) and the other types of carcinoma (surgical therapy).
  • Therefore, we undertook to ascertain its usefulness in the diagnosis of squamous carcinomas in the anal canal.
  • We retrieved 24 anal squamous carcinomas, 68 colorectal adenocarcinomas (including a tissue microarray), and 32 colorectal neuroendocrine carcinomas from the archives at the University of Michigan, and immunostained them for the p63 antigen.
  • It also stained the dysplastic epithelial cells in adjacent areas of anal intraepithelial neoplasia.
  • We report that the p63 immunostain is a highly specific and useful tool in the diagnosis of carcinomas of the anal canal.

COS Scholar Universe. author profiles.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Diagnostic problems in anal pathology.
  • Anal squamous cell carcinoma and its precursor lesions are increasing in incidence in the United States and Europe.
  • Screening protocols for at-risk patients are under active investigation and pathologists are often asked to assess anal canal and perianal biopsies for the presence of dysplasia and/or invasive carcinoma.
  • Because underdiagnosis and overdiagnosis of anal cancer and precancer may lead to inappropriate treatment, it is important for the pathologist to be aware of current screening strategies, specific risk lesions, and the role of pathology in initial diagnosis and evaluation of anal biopsy and/or resection specimens.
  • Standardized histologic criteria and uniform terminology should be used for reporting all anal canal and perianal squamous intraepithelial lesions.
  • HPV subtyping, anal cytology, and recently identified biomarkers, such as p16 and Becton Dickinson ProEx C may provide additional information in problematic cases, but it is important to be aware of the limitations of these assays.
  • HPV has been linked to all the major histologic subtypes of anal carcinoma (eg, basaloid, cloacogenic, transitional, etc.) and this association is strongest for anal canal lesions.
  • With the possible exception of the microcystic pattern, histologic subtype does not seem to predict prognosis; and anal squamous cell carcinomas should be classified as either keratinizing or nonkeratinizing.
  • Poorly differentiated squamous cell carcinomas have a worse prognosis and should be distinguished from poorly differentiated adenocarcinoma, melanoma, and neuroendocrine tumors.
  • As all anal condylomata may harbor foci of high-grade dysplasia or invasive carcinoma, careful sectioning and complete histologic examination is required.

  • [Title] Immunophenotypic characterization of anal gland carcinoma: loss of p63 and cytokeratin 5/6.
  • Anal gland carcinoma (AGC) is a rare perianal invasive cancer composed of tubular glands lined by cuboidal epithelium.
  • The clinical features and histogenesis of AGC are not well understood and its origin from anal glands is often difficult to prove.
  • Little is known about immunophenotypic features of AGC that could be useful in establishing the diagnosis.
  • This study evaluated the immunohistochemical profile of 2 cases of AGC in comparison to anal glands from 11 hemorrhoidectomy specimens.
  • In biopsies from this case, the neoplastic anal glands had a tubular pattern, whereas most glands in the resection specimen exhibited mucinous features.
  • Normal anal glands showed immunoreactivity for myoepithelial and basal cell markers CK5/6 and p63 in basal and parabasal cell layers and for CK7 in superficial cell layers.
  • Anal gland carcinoma shares negativity for CDX2 and CK7+/CK20- profile with normal anal glands.
  • No evidence of myoepithelial cells was found in normal or malignant anal glands.
  • These data may be useful in establishing the diagnosis of AGC.

  • Immunohistochemical stains demonstrated that the Paget's cells were CK7+/ CK20-/GCDFP+, whereas the rectal adenocarcinoma was CK7+(variable)/CK20+/GCDFP-.
  • This discordant immunoprofile supported our impression that the Paget's disease in this patient was of cutaneous apocrine origin rather than a pagetoid extension from the patient's nearby rectal adenocarcinoma-to our knowledge a hitherto undocumented occurrence.

  • Guided primarily by the World Health Organization/International Association for the Study of Lung Cancer criteria for pulmonary neuroendocrine tumors, we were able to classify 87 high-grade GI tract tumors that initially carried a diagnosis of either poorly differentiated carcinoma with or without any neuroendocrine characteristics, small cell carcinoma, or combined adenocarcinoma-neuroendocrine carcinoma into the following 4 categories.
  • The fourth was poorly differentiated adenocarcinoma (n=17).
  • Further analysis showed that most HGNECs arising in the squamous lined parts (esophagus and anal canal) were small cell type (78%), whereas most involving the glandular mucosa were large cell (53%) or mixed (82%) type; associated adenocarcinomas were more frequent in large cell (61%) or mixed (36%) type than in small cell type (26%); and focal intracytoplasmic mucin was seen only in large cell or mixed type.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • The purpose of this study was to determine whether SOX2 is differentially expressed in squamous cell carcinomas versus adenocarcinomas of the esophagus and rectum/anal canal and to compare its expression to p63, cytokeratin 5/6, and CDX2.
  • In total, 93 tumors were evaluated: 26 esophageal squamous cell carcinomas, 23 esophageal adenocarcinomas, 21 squamous cell carcinomas of the anal canal, and 23 rectal adenocarcinomas.
  • SOX2 was expressed in 81% of esophageal squamous cell carcinomas and 91% of anal canal squamous cell carcinomas, compared to 13% and 17% of esophageal and rectal adenocarcinomas, respectively. p63 was expressed in 96% of esophageal squamous cell carcinomas and 100% of anal canal squamous cell carcinomas; the single squamous cell carcinoma negative for p63 was strongly positive for SOX2.
  • Cytokeratin 5/6 was expressed in most esophageal and anal canal squamous cell carcinomas, but was also positive in 43% of esophageal adenocarcinomas and 13% of rectal adenocarcinomas.
  • In summary, SOX2 is preferentially expressed in squamous cell carcinomas of the esophagus and anal canal compared to adenocarcinomas from these sites.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • The last case was associated to a low rectal adenocarcinoma.
  • We performed a transanal resection of the rectal adenocarcinoma.
  • Anorectal adenocarcinoma was already existing in two cases, synchronous in 48, and subsequent to diagnosis in 11.
  • The review of the literature allows a clear identification of the primitive EMPD and the form associated to anorectal adenocarcinoma and little information about cases associated with synchronous adnexal adenocarcinoma.
  • CONCLUSIONS: Up to now, no clear guidelines have been established for the diagnosis of EMPD.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • In 132 cases (27%) it was shown to be a false positive, mainly due to imperfect cleansing of the anal canal; in 284 cases (58%) benign disease was demonstrated (hemorrhoids in 192 patients, abscesses in 21, perianal fistulas in 18, inflamed lymph nodes in 27, polyps in 16).
  • In 34 patients (7%) a malignant tumor was found (infiltration of the anterior rectal wall by a prostatic adenocarcinoma in 13, and a primitive adenocarcinoma of rectal origin in the remaining 21).
  • It can be concluded that transrectal US does not permit a certain diagnosis of the nature of rectal disease, but does raise a diagnostic suspicion that can orient the surgeon to schedule more invasive diagnostic investigations.

  • [Title] T1 neuroendocrine carcinoma of anal canal after transanal resection for intramucosal adenocarcinoma.
  • Neuroendocrine carcinomas of the anal canal are rare, representing 1% of malignant tumors of the anal canal.
  • We describe the case of a 63-year-old female with T1 neuroendocrine carcinoma of the anal canal arising from the site of a previous transanal excision performed 13 months earlier for intramucosal adenocarcinoma of the anal canal.
  • In this case, it is likely that the neuroendocrine tumor, which infiltrated into the submucosal layer with venous invasion, had developed over the intervening 13 months following the original transanal excision of the adenocarcinoma.
