title: [A case of proximal type epithelioid sarcoma of the perineum].
abstract: Epithelioid sarcomas are rare soft tissue neoplasms which occur more often in young people. They tend to relapse, metastatize and show poor prognosis. Proximal-type epithelioid sarcomas arise from the more proximal part of body and are more malignant than distal-type epithelioid sarcomas. We present a case of proximal-type epithelioid sarcoma which occurred in the perineum. A 24-year-old male visited our hospital with the chief complaint of pain in the perineum. Computed tomography and magnetic resonance imaging showed a tumor 30×23×17 mm in diameter in the perineal region. The tumor was excised regionally and the pathological examination with immunohistochemical staining revealed that the tumor was proximal-type epithelioid sarcoma. The patient is free of recurrence and metastasis one year after local excision.
