Clear-cell sarcoma of tendons and aponeuroses studied by immunoscintigraphy

Clear-cell sarcoma is a rare tumor that arises in association with tendons and aponeuroses. Although it shares with malignant melanoma several histologic and ultrastructural features, it has a clinical course different from that of conventional melanomas. A case of clear-cell sarcoma studied by immunoscintigraphy with 99mTc-labeled F(ab')2 fragments of the monoclonal antibody 225.28 S is reported.
