title: Small blue round cell tumor: an unusual case presentation in the foot.
abstract: Small blue round cell tumors of childhood rarely present in the foot or ankle. The following is a case presentation of an 18-year-old male with a large soft-tissue mass of the foot with associated lung metastasis. A definitive diagnosis could not be fully made, even with immunohistochemical and genetic testing. Diagnosis favored poorly differentiated synovial sarcoma.
