Mucinous tubular and spindle cell carcinoma kidney with sarcomatoid and rhabdoid differentiation- A rare entity

Mucinous tubular and spindle cell neoplasm is a rare renal tumor with favourable outcome. Sarcomatoid change is described in many renal cell carcinomas, indicative of a worse clinical course. We report a case of mucinous tubular and spindle cell neoplasm with areas having sarcomatoid and rhabdoid morphology with large areas of necrosis. Sarcomatoid change is very rare in mucinous tubular and spindle cell tumor and we could find only 4 similar cases in the published literature.
