Overview

NCI Definition: A rare malignant neoplasm with melanocytic differentiation characterized by the presence of polygonal or spindle shaped clear cells. This sarcoma usually affects the tendons and aponeuroses and is associated with a poor prognosis due to recurrences and metastases. [1]

Clear cell sarcoma of soft tissues most frequently harbor alterations in EWSR1, ATF1, CREB1, CDKN2A, and SRSF2 [2].

Most Commonly Altered Genes in Clear Cell Sarcoma of Soft Tissue

EWSR1 Fusion, EWSR1-ATF1 Fusion, ATF1-EWSR1 Fusion, EWSR1-CREB1 Fusion, and CREB1-EWSR1 Fusion are the most common alterations in clear cell sarcoma of soft tissue [2].
