Abstract
Two cases of clear cell sarcoma of tendons and aponeuroses are reported. The 1st patient was a 19 yr old man with a tumor in the medial collateral ligament of the knee. The tumor was enucleated, and after postoperative radiotherapy a wide local excision was done. The patient was symptomless 4 1/2 yr after the operation. The other patient was a man aged 68 with a tumor between the medial malleolus and the Achilles tendon. He also received postoperative radiotherapy after enculeation. Three months later a metastasis was noticed in the ipsilateral parailiac nodes. The patient died 16 mo. after the operation. The histology and clinical course of the 2 cases are analyzed. Some integrative remarks based on earlier reports of 33 cases and the present 2 cases are presented.
