Which type of renal cell carcinoma has best prognosis?

Chromophobe renal cell carcinoma: This accounts for around 5% of cases. Of these three types, clear cell carcinoma has the worst prognosis, and chromophobe renal cell carcinoma the best, with only 7% of cases going on to affect more distant parts of the body.

What is a CK7 marker?

Cytokeratin 7 (CK7) is a type II basic low molecular weight cytokeratin that is found in simple epithelia in a variety of organs, including all epithelia in the female genital tract. 305,306. Epithelial tumors of the ovary and fallopian tube all exhibit cytoplasmic and/or membrane staining for CK7.

Which is a positive cytokeratin in renal parenchyma?
