Simultaneous Chromophobe renal cell carcinoma and squamous renal cell carcinoma

Chromophobe renal cell carcinoma (CHRC) is a neoplasm of the kidney with clinicopathologic peculiarities that seems to be of better prognosis than conventional renal cell carcinoma. Classical and eosinophilic types are the two histological variants recorded. Also, it has been described in association with carcinoma of collecting ducts, conventional renal cell carcinoma and sarcomatoid renal cel...

Sarcomatoid Transrormation of Chromophobe Renal Cell Carcinoma

Sarcomatoid Chromophobe Renal Cell Carcinoma with Heterologous Component

Clear cellrenal cell carcinoma (RCC) is the most common malignant renal tumor in adults, while chromophobe RCC (CRCC) is the third most common. Any subtypes of RCC can undergo sarcomatoid differentiation, but heterologous differentiation in sarcomatoid area is very rare in RCC. Here a61-year male is presented with hematuria and palpable mass. Clinicoradiologically, RCC was considered and left r...

Eosinophilic variant of chromophobe renal cell carcinoma.

Chromophobe renal cell carcinoma is a distinct subtype of renal cell carcinoma that accounts for 5% of all renal tumors. This subtype is further subdivided into two variants, classic and eosinophilic, with the latter variant being less frequent. We report two cases of the eosinophilic variant of chromophobe renal cell carcinoma diagnosed at our institution between January 2008 and December 2012.
