1/3. Perianal mucinous adenocarcinoma.Perianal mucinous adenocarcinoma, also known as anal duct or anal gland carcinoma, is a rare tumor usually associated with chronic fistulae-in-ano. Whether the tumor occurs primarily and the fistula is a secondary manifestation, or whether this tumor arises in a chronic fistulous tract is debatable. diagnosis can be made only by open deep biopsy of the buttock mass, and, due to the low grade histologic appearance of the malignancy, an incorrect diagnosis is frequently made. Treatment is abdominoperineal resection with wide removal of the buttock mass.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
2/3. Primary adenocarcinoma of an anal gland with secondary perianal fistulas.A case of primary mucinous (colloid) adenocarcinoma associated with multiple perianal fistulas and a supra-anal intergluteal abscess of a short duration is described. The origin of this tumor has been much debated. Some believe that the tumor occurs primarily in an anal duct or its glands with secondary fistula formation, whereas others claim that the tumor arises in a chronic fistulous tract. The present study substantiates the former concept on the basis of the mode of clinical presentation and the pathologic findings of a large tumor, without involvement of the anorectal mucosa. The residual anal ducts and glands were found in close relationship with the tumor.- - - - - - - - - - ranking = 6keywords = gland (Clic here for more details about this article) |
3/3. Anal gland adenocarcinoma presenting as painless scrotal swelling in a 73-year-old man: a case report.A 73-year-old man presented with progressive painless scrotal swelling without systemic, urinary, or anorectal complaints. The scrotal lymphedema was due to massive bilateral metastatic replacement of the superficial inguinal lymph nodes. The primary tumor was an inoperable, rapidly fatal adenocarcinoma arising from the anal glands of the upper canal. Thus, in the evaluation of scrotal swelling of obscure etiology in older patients, occult carcinomas of the anal glands must be considered and appropriate steps taken to establish the diagnosis.- - - - - - - - - - ranking = 6keywords = gland (Clic here for more details about this article) |
