Primary Renal Synovial Sarcoma: A Rare Case Report

Abstract

Synovial sarcoma (SS) is mainly derived from soft tissues. Primary renal SS is a very rare malignancy with around 60 cases reported in the literature. We report a renal mass which was undistinguishable from urothelial carcinoma clinically and pathologically but diagnosed as a primary renal SS at the definitive pathological diagnosis.
