Huge Anorectal Malignant Melanoma and Treatment

Abstract

Malignant melanoma of the anorectum is a very uncommon malignancy. It is associated with relatively poor prognosis and surgery is the only treatment. In this report, we present the treatment options for huge anorectal malignant melanoma. An 83-year-old female patient presented with anorectal pain and hemorrhage. A tumor extending from the verge of the anus to 6 cm into the rectum was observed on colonoscopy. Biopsy revealed malignant melanoma. Abdominoperineal resection was performed. Surgery is the most widely accepted treatment approach. Abdominoperineal resection should be the first-line treatment who have large tumors.
