Clear cell sarcoma in the era of sentinel lymph node mapping.

Clear cell sarcoma of the tendons and aponeuroses (CCSTA) are rare aggressive soft tissue tumors with tendency for lymph nodes dissemination. Lymph node involvement is a correlate for prognosis. We present three patients with CCSTA in whom simultaneous sentinel lymph biopsy (SLNB) and resection was performed. Sentinel lymph node mapping may have a role in clear cell sarcoma from a prognostic standpoint. Further investigations are needed for validation.
