Abstract :

Rectoanal melanoma is a rare tumour and usually presents with advanced disease. Rectoanal melanoma is more commonly seen in women, and the median age at diagnosis is 60 years. Most patients seek medical attention for peri– anal discomfort or bleeding per rectum. Frequently the lesions are misdiagnosed as haemorrhoids and treated conservatively before the diagnosis is made. Up to 25% of lesions can be amelanotic. Unlike cutaneous melanoma, no known risk factors are present. Surgical excision remains the cornerstone of therapy. There are no trials definitively proving abdominal perineal resection (APR) or wide local excision (WLE) to yield superior long–term survival. APR may offer a higher rate of local control, whereas WLE offers a much less morbid operation .Median survival is 20 months.
