title: [Case of local recurrence of the periurethral proximal-type epithelioid sarcoma successfully treated by repeated regional excision].
abstract: Proximal-type epithelioid sarcomas are rare soft tissue neoplasms occuring in the soma or thigh and often repeat recurrence and metastasis. We present a case of locally recurrenced proximal-type epithelioid sarcoma that could be treated by regional excision alone. A 62-year-old man visited our institute for a growing mass in the perineal region. Computed tomography (CT) showed a periurethral tumor 22 x 13 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. Local recurrence of the tumor occurred 2 years 7 months later without any metastatic lesion, and regional excision was performed again. Pathological diagnosis was proximal type epithelioid sarcoma and it was identical to the primary tumor. The patient is free of the disease 1 year after the second surgery of the tumor.
