Clear cell sarcoma of tendons and aponeuroses also called as malignant melanoma of soft parts is a rare tumor of neural crest origin with 70% of them possessing balanced translocation t(12; 22). Approximately 50% of the tumor produces melanin which often shows focal pigmentation or needs special stains to demonstrate melanin. Production of excessive melanin by this tumor is very unusual and very few case reports are available in literature. We report a case of Clear cell sarcoma with excessive melanin production in a 50-year-old female patient involving the left popliteal fossa.
