Anorectal Melanoma: a 10-Year Study in the North-East of Iran

Abstract

Background: Anorectal melanoma is one of the rare but significant malignancies of the anorectal area. This malignancy currently accounts for 1% of all types of melanoma and less than 1% of all the anorectal area malignancies. Very rare cases of this disease have been reported worldwide. Anorectal melanoma is mostly diagnosed while treating other benign conditions of this area such as hemorrhoids with conventional modalities. Its treatment of choice has always been a controversial issue.
