A Rare Encounter: Anorectal Melanoma as a Cause of Rectal Bleeding.

Anorectal melanoma is a rare malignancy. It has a poor prognosis due to delayed detection and aggressive tumor biology. In addition, there are no established guidelines for its staging or management, which further complicates the delivery of care. We present a case of an advanced anorectal melanoma in a 63-year-old male from Sri Lanka who presented with per-rectal bleeding and altered bowel habits. He underwent laparoscopic abdominoperineal resection due to the distal site and advanced stage of the tumor and was then scheduled for adjuvant chemotherapy, which he refused in favor of Ayurvedic treatment.
