Sarcomatoid differentiation in a chromophobe renal cell carcinoma. H&E stain.

Renal cell carcinoma with sarcomatoid differentiation is a malignant epithelial derived kidney tumour with malignant mesenchymal differentiation.

These tumours are not recognized as a distinct type of renal cell carcinoma;[1] they are classified by the non-sarcomatous component. If a renal tumour is purely sarcomatous it is renal cell carcinoma, unclassified.
