Summary
A case of a patient with benign leiomyoma, adherent to the musculature of the anal canal, is reported. If this can be considered a tumor of the anal canal, it is believed to be the third case reported in English medical literature. Perianal leiomyomas grow away from the lumen of the rectum and musculature of the anal canal and cause few, if any, intestinal symptoms. The tumor can be removed easily by local excision and no recurrences have been reported. Nevertheless, we believe that careful follow-up procedures should be adopted to determine if malignant degeneration develops.
Medical literature on leiomyomas is reviewed briefly.
