(30) In addition to clear cell RCC, the differential diagnosis should include several other types of RCCs in which the tumor may be primarily composed of clear cells, such as chromophobe
, clear cell papillary, and Xp11 translocation and papillary RCCs.
GHG in granular cell carcinoma, chromophobe
cell carcinoma, oncocytoma of the kidney.
In this study, we investigated the MRI features of renal tumors, namely T2 signal intensities, T2 signal intensity ratios, enhancement patterns, and enhancement ratios that might allow differentiation of oncocytoma from chromophobe
Among them, the stellate cells were contradictory due to the absence of secretory granules, some scholars think it belonged to the chromophobe
cells, but others disagreed with it (Soji & Herbert, 1989; Allaertset al., 1996).

renal cell carcinoma," American Journal of Roentgenology, vol.
All other groups contained 20 tumor samples (clear cell RCC, eosinophilic/oncocytic variant of clear cell RCC, chromophobe
RCC, eosinophilic/oncocytic variant of chromophobe
RCC, and oncocytoma) according to the AJCC 2010/UICC 2009 classification.
carcinoma is typically associated with a favorable prognosis, but aggressive behavior can be seen in a subset, including in hybrid tumors with a higher--grade component.
(7) Other histological variants such as papillary, chromophobe
, oncocytoma, collecting duct, or unclassified are less common.
cell carcinoma accounts for only 3-5% of all RCCs and carries a better prognosis than clear cell RCC.
Renal cell carcinoma (RCC) can be divided into several different types of cancer [69-71], including chromophobe
RCC (CHRCC), collecting duct carcinoma (CDC), clear cell RCC (CCRCC), and papillary RCC (PRCC).
In addition, a previous report indicated that CD10 positivity is useful for pathological diagnosis of clear cell or papillary RCC, and we could eliminate the chromophobe
Herein, we describe a rare case of incidental de novo eosinophilic variant of chromophobe
RCC (ChRCC) in a renal allograft 11 years after transplantation, discuss the histopathological differential diagnosis, and comment on cancer screening in renal transplant recipients.
