title: [Epithelioid sarcoma of the right hand].
abstract: A 35-year-old man presented with swelling, indurations and nodules on the thumb, wrist and fingers of the right hand. History revealed that the findings were slowly progressive and had been present for at least eight years. Histopathologic analysis of a nodule showed a diffuse infiltrate with atypical spindle-shaped cells and expression of cytokeratin, epithelial membrane antigen (EMA) and CD34; the diagnosis of epithelioid sarcoma (ES) was made. Because of diffuse extension of the tumor, forearm amputation was performed along with axillary dissection and local radiotherapy because of axillary lymph node metastases. ES is a rare subtype of soft tissue sarcoma with a harmless appearance and indolent course over years. ES represents a diagnostic challenge, with consequent delay in diagnosis and adequate treatment. The most important measure in the treatment of ES is early surgical excision with adjuvant radiotherapy if local metastases are present.
