Abstract: We present a case of 50 year old female who presented to the out patient department with complaints of
bleeding per rectum and mass per rectum since 2 months. Per rectal examination revealed a pedunculated soft mass at the
anal verge. The patient underwent excisional biopsy and during this surgery another mass was palpable whose upper
border could not be felt. Histopathologic examination and immunohistochemistry(S-100) of polyp were suggestive of
malignant melanoma. Colonoscopy examination revealed a proliferative lesion at 4 o’clock position involving the one
third circumference of rectum. The patient underwent abdominoperineal resection and is on adjuvant chemoradiotherapy
