CLEAR CELL SARCOMA OF GLUTEAL REGION MALIGNANT MELANOMA OF SOFT PARTS

Abstract

Clear cell sarcoma (CCS) is described as variant of sarcoma characterized by prominent clear cells showing features similar to malignant melanoma of soft parts. This neoplasm was first described by Dr. Franz m. Enzinger. Primary CCS usually arises in deeper soft tissues, in association with fascia, tendons, or aponeuroses. Clear cell sarcoma (CCS) is a rare malignant tumor with a propensity for slow progressive invasion. It is a tumor derived from Melanoblast like cell. They occur most commonly in the extremities, with a predilection for young females. Clear cell sarcoma of tendons and aponeuroses (malignant melanoma of soft parts) and conventional malignant melanoma may demonstrate significant morphologic overlap at the light microscopic and ultra structural level. The tumor is very rare and can pose clinical challenges in early diagnosis. This case report demonstrates an unusual site of occurrence for clear cell sarcoma.
