摘　　要：Anorectal melanoma is a rare tumor representing less than 1% of anorectal cancers and around 0.3% of malignant melanomas. Its prognosis is particularly poor due to the early occurrence of metastases. We report the case of a 65-year-old man presenting with rectorrhagia and anal pain, initially diagnosed as hemorrhoidal disease. Subsequent proctological examination revealed an ulcerating-bourging tumor, confirmed histologically as an anorectal melanoma. After a normal extension workup, an abdominoperineal amputation was performed. Anorectal melanoma is a pathology with a poor prognosis, requiring early diagnosis to improve chances of survival.Anorectal melanoma is a rare tumor representing less than 1% of anorectal cancers and around 0.3% of malignant melanomas.
