Abstract

Anorectal melanomas represent less than 1% of all anorectal cancers and 0.3% of malignant melanomas [1]. Rectal localization is rare, accounting for 0.3% of all melanomas [2]. It is often secondary to infiltration of the rectal mucosa by an anal-derived process originating from melanocytes normally present in the squamous epithelium of the pectineal zone and in the transitional epithelium above the pectineal line [6-7]. Its prognosis is dreadful due to the early occurrence of metastases. We report an observation from the Department of Medicine B, Ibn Sina University Hospital, and Rabat.
