Abstract :

Melanomas are primarily a disease of the skin as melanocytes are present abundantly in the skin. Melanocytes are also present in the eyes, nasal Cavity, oropharynx, vagina, urinary tract, rectum, and anus. Though rare , malignancies from melanocytes can arise from any of these areas. Mucosal melanomas account for approximately 1.2% of all melanomas, and anorectal melanomas account for fewer than 25% of all mucosal melanomas. Amelanotic melanoma of the anorectum is a very rare entity. Only few cases have been identified and documented. Because of very low documented cases, treatment strategies have not been developed, which makes managing these cases a tough task. This is a 60 year male with no co morbidities, presenting with difficulty in defecation, later diagnosed to have primary ano – rectal amelanotic melanoma
