Metastatic Anorectal Melanoma: A Case Report

Abstract

Introduction: Anorectal melanoma is a rare and aggressive malignancy. Patients commonly present with advanced or metastatic disease. Case Presentation: We report the case of a 60-year-old man who presented with constipation and per rectal bleeding. Abdominal CT scan showed metastasis in liver and spleen along with disease spread in inguinal, iliac and abdominal lymph nodes. He was treated with single agent Dacarbazine and ultimately succumbed to the disease. Conclusions: Anorectal melanoma remains a disease with dismal prognosis especially when the patient presents with distant metastasis.
