Malignant Melanoma of the Rectum – A Rare Entity

Malignant Melanoma is very rare in the rectum. Long-term survival is rare, as most patients die of disseminated systemic disease regardless of treatment. A 65-year old patient presented with the history of painless bleeding per rectum since last 6 months. Recto-Sigmoidoscopy revealed a hard growth over the right lateral wall of the rectum, biopsy of which was reported to be malignant melanoma with a possibility of poorly differentiated carcinoma. Immunohistochemistry confirmed the diagnosis of malignant melanoma. There is a controversy regarding the best surgical treatment because of its poor prognosis. We report this case because of its rarity.
