OBJECTIVE: There has been no report on useful immunohistological markers for epithelioid sarcoma (ES) so far. The purpose of this study is to evaluate the positivity and specificity of CA125 as a marker for the correct diagnosis of ES. METHODS: This study was performed in 11 patients with ES (nine men and two women; distal type: 10 cases; proximal type: one case), 78 patients with other soft tissue tumors and nine with benign granulomas. The other soft tissue tumors consisted of six synovial sarcomas, six clear cell sarcomas, eight leiomyosarcomas, six rhabdomyosarcomas, five malignant peripheral nerve sheath tumors, ten malignant fibrous histiocytomas, 17 desmoid tumors, 14 liposarcomas, six squamous cell carcinomas (cutaneous SCC of the distal extremities), two rheumatoid nodules and seven foreign body granulomas...
