Abstract:

Anorectal melanoma is an aggressive mucosal melanocytic malignancy. It is rare, and approximately one third of them are amelanotic. They can resemble benign polypoid lesions of ano-rectum. Symptoms are non-specific and include anal bleeding, anal mass, and pain. The pre-operative diagnosis remains difficult as it is not suspected due to rarity of the disease. Immunohistochemical studies on biopsies help in diagnosis. Anorectal melanoma carries a poor prognosis as it is often diagnosed late. Optimal therapy is still evolving and often surgical resection remains the therapy of choice.
