title: Carcinoma of anal-ductal origin: report of a case.
abstract: A 57-year-old man who had a carcinoma proven to be of anal ductal origin is presented. Recurrent perianal fistulas were treated locally for two years until biopsy proved the malignancy. Gross and histologic examination of the specimen removed by abdominoperineal resection demonstrated the anal ductal origin of this tumor. Recurrence was seen in less than a year.
