Clear Cell Sarcoma

Clear cell sarcoma (CCS) of soft tissue, not to be confused with clear cell sarcoma of the kidney, is a rare type of cancer primarily affecting teens and young adults. CCS tumors are most commonly found in the limbs, feet and hands. They also develop in the gastrointestinal tract and throughout the torso and have also been found in the genitals and head. Clear cell sarcoma is a translocation-associated sarcoma, typically EWSR1/ATF1.
