[Anal canal basaloid carcinoma with vaginal invasion which was recurrence-free for 5 years postoperatively].

We performed abdomino-perineal resection of the rectum and partial resection of a vagina in a 78-year-old woman on a diagnosis of anal canal basaloid carcinoma with vaginal invasion. We did not perform specific adjuvant therapy pre- or postoperatively, but no recurrence appeared for 5 years. Anal canal basaloid carcinoma is a comparatively rare disorder, and the prognosis is relatively good.
