Human chromophobe cell renal carcinoma

1985

Twelve renal cell carcinomas composed of "chromophobe" cells are described. This is the first report of renal chromophobe cell tumors in humans neoplasms of this cell type having been described previously only in experimentally induced adenomas in animals. By light microscopy chromophobe cells have slightly opaque or finely reticular cytoplasm when stained with haematoxylin and eosin. They may be distinguished from the clear cells of hypernephroid renal cell carcinomas by the strongly positive reaction of their cytoplasm with Hale's (1946) colloidal iron method and the weaker positive reaction with alcian blue. Vesicular structures, often containing internal vesicles, and possibly derived f…
