[Melanomas of the anorectal region]

Melanoma of the anorectal region is a rare disease which makes up 1.8% of all rectal malignancies and 1.4% of all cases of melanoma. Surgery is the only radical procedure for the treatment of anorectal melanoma. Abdomino-perineal extirpation of the rectum proved most radical. Overall five-year survival rate was 17.0 +/- 5.3%.
