Abstract:
Although on anorectal malignant melanoma is relatively rare, we report two cases, that of a 88-year-old woman, and a 78-year-old man. Both patients were admitted to the hospital due to rectal bleeding and were diagnosed as having rectal carcinoma. Following an abdominoperineal rectal amputation, a pathological examination of the resected specimens revealed a malignant melanoma. Thus, it is necessary to carry out a careful examination of patients with tumors of the anorectal region when there is the least suspicion of a malignancy.
