Abstract

Sarcomas of the kidney could be a clear cell sarcoma or Monophasic Synovial cell sarcoma (MSC) of the kidney is a tumor which is rare in kidney and is associated with poor prognosis. Differentiating this from other tumours is through histology and immunohistochemistry because of its characteristic spindly tumor cells with no epithelial component and immunopositivity for bcl2, CD99 and TEL1. It is important to distinguish because of its poor prognosis and chances of relapse.
