Chromophobe cell renal carcinoma and its variants--a report on 32 cases.
(12,21) In these studies, PAX8 was noted in 95% to 98% for clear cell RCC, 90% to 100% for papillary RCC, 82% to 88% for
chromophobe cell RCC, 44% to 71% for sarcomatoid RCC, and 61% to 95% for oncocytoma.
Sarcomatous transformation of
chromophobe cell renal carcinoma.
A rhabdoid component may be observed among renal clear cell carcinomas but also in papillary carcinomas,
chromophobe cell carcinomas, or collecting duct carcinomas.
(5) Moreover, mixed tumors containing both oncocytic cells and
chromophobe cell nets have been described recently.
