A rare case of Anal Malignant Melanoma Disguised as Hemorrhoid

Tumors of the anal canal and perianal skin are rare. They show a varied presentation and the malignant tumors can mimic common benign pathology thereby delaying the diagnosis and timely treatment of the patient1. Anal melanoma is rare, representing 0.2-0.3% of all melanomas and 4% of all anal tumors. Diagnosis of perianal melanoma is quiet challenging as it can mimic hemorrhoids and rarely fissures and perianal abscess. The early diagnosis is very important as the prognosis is very poor2.
