Primary synovial sarcoma (PSS) of the kidney is a rare entity. Since morphologic differentiation from other tumors like metastatic sarcoma, sarcomatoid renal cell carcinoma, retroperitoneal liposarcoma may be difficult, other diagnostic modalities like immunohistochemistry, cytogenetic & advanced molecular analyses need to be employed.Despite its rarity & non specific presentation, pathologist and clinicians should consider synovial sarcoma in the differential diagnosis of renal masses for the proper management of patients, especially when histopathological examination shows malignant spindle cell neoplasm of kidney.
