title: Biphasic synovial sarcoma in a 13-month-old girl.
abstract: Synovial sarcoma is a malignant mesenchymal neoplasm which commonly occurs in the extremities of adults. We report on a 13-month-old girl with synovial sarcoma in the lateral aspect of her right ankle. The tumor was treated with total excision and 50Gy of irradiation. Histopathologic examination of the excised tumor revealed a biphasic synovial sarcoma. There was no evidence of local recurrence or distant metastasis of the tumor at follow-up examination 24 months postoperatively.
