The American Journal of Surgical Pathology, 1988
The normal gross and microscopic morphology of the anal canal is described, including the more common variants. Constant problems in the literature are the confusing terminology and the relation of the histological zones to the so-called cloacal membrane. For this reason, the review includes remarks on the history, embryology, and nomenclature.

Melanocytes in the anal canal epithelium
Histopathology, 1991We studied the presence of melanocytes in the various epithelial zones of the anal canal, using a recently introduced melanocyte‐specific antibody (HMB‐45) together with antibody to S‐100 protein. In normal anal canals and in haemorrhoids, melanocytes, defined as intraepithelial HMB‐45/S‐100 positive cells, were frequently demonstrated in the anal ...

Congenital fibrolipoma of anal canal
The Indian Journal of Pediatrics, 2003Although rare, congenital lipomatosis presents during first few months of life as large sub-cutaneous fatty masses on chest with extension into skeletal muscle bundles. Only a few such cases have been reported in the literature. A rare case of congenital fibrolipoma of anal canal in a 3-day-old male child is being documented in the present report.

Development of the anal canal muscles
Diseases of the Colon & Rectum, 1991The anal canal muscles development is studied in 18 human embryos. The external anal sphincter results to origin common with the urogenital sphincter from the cloacal sphincter. The muscle, after its appearance, is subdivided into two portions from a thin mesenchymal layer.

Endosonography of Anal Canal Diseases
Ultrasound Quarterly, 2002Anal endosonography became a valuable imaging method for diagnosis of anal diseases because of its accessibility, relative simplicity of performance, and low cost. It is used most often to detect anal sphincter defects, to classify anal fistulas and perianal abscesses, and to stage anal tumors.

The purpose of conservative treatment is the control of rectal carcinoma without bowel resection. Conservative treatment by irradiation has long been a subject of controversy, because it contradicts two generally held notions: first, that adenocarcinoma of the rectum is only slightly radiosensitive; second, that rectal cancer can only be cured by ...

Anal cancer is a rare type of gastrointestinal malignancy. Over 80% of anal cancers are of squamous origin and arise from the squamous epithelium of the anal canal and perianal area. Recent evidence has demonstrated that the incidence of squamous cell carcinoma of anal cancer increases in immunocompromised patients. Approximately 10% are adenocarcinoma

Treatment of anal canal carcinoma
Cancer, 1985The treatment philosophy of anal canal carcinoma is changing. Abdominoperineal resection (APR) with a permanent colostomy is beginning to be replaced by lesser surgical techniques, such as excisional biopsy in a multimodality approach. Radical radiation therapy is capable of eradicating the primary tumor and yielding a high survival rate.
