A Case of the Anal Carcinoma Coexisting with Tuberculotic Anal Fistula

Abstract

The coincidence of malignant disease with tuberculosis in the digestive organ has been recently rare. We encountered a case of the anal carcinoma coexisting with tuberculotic anal fistula. A 63-year-old woman who complained anal bleeding during neurological therapy after cerebral bleeding and was diagnosed the anal carcinoma, underwent abdominoperineal excision of the rectum with inguinal lymph nodes dissection. Histological examination revealed tuberculoma in the anal fistula around the adenocar cinoma and in the inguinal lymph nodes. The patient was discharged after uneventful recovery, and is currently alive and well 3 years and 9 months after surgery, with neither recurrence of the cancer nor tuberculosis. It appears to be important that anal fistula with protracted course should be taken into consideration of concomitant cancer and tuberculosis.
