Abstract

We present a case of primary malignant melanoma of the anus in a patient who was not an ideal surgical candidate due to past medical history. Primary melanoma of the gastrointestinal tract is not as well characterized as cutaneous malignant melanoma within the medical literature, but should still be considered within differential diagnosis especially if the mass is seen within the anorectal region. These cancerous tumors typically have late presentation which leads to worse prognosis as metastasis has often occurred before diagnosis. Standard treatment options include surgical resection, chemotherapy, immunotherapy, and local radiation.

Histological hematoxylin and eosin stain at 10x magnification morphologically consistent (arrow) with primary malignant melanoma of the anus.
