Primary Synovial Sarcoma of the Kidney: A Rare Presentation.

Primary renal synovial sarcoma (PRSS) is a rare entity. It should be considered as one of the differential diagnoses of spindle cell tumors of the kidney. Immunohistochemistry and genetic translocation studies should be used to confirm the diagnosis. Because of a lack of consistent literature data regarding the treatment options, management of PRSS remains a therapeutic challenge. In view of the chemosensitive nature of the tumor, we propose a multimodality treatment in form of surgery and chemotherapy in patients with PRSS. Here we report a rare case of PRSS in a 17-year-old adolescent.
