We present four cases of the recently characterized chromophobe cell renal carcinoma.
Gross hematuria, palpable flank mass and flank pain were the main symptoms of
patients. With chromophobe cell renal carcinoma all tumors were solitary pale brown or
beige colored mass, ranging from 6.0 to 10.5cm in diameter. Microscopically two cases
were typical type and the other two cases were eosiophilic type. All of them showed
strong reactivity for Hale's colloidal iron stain, cytokeratin and epithelial membrane
antigen, but negative for vimentin. Ultrastructually characteristic invaginated
microvesicles, 180-440nm in diameter, were identified in the cytoplasm. DNA ploidy
studies revealed an aneuploid cell population in two cases of eosinophilic type. No
patients showed recurrent tumor during the follow up periods, ranging from 5 to
92months.
