Eosinophilic variant of chromophobe renal cell carcinoma.

Chromophobe renal cell carcinoma, eosinophilic variant with papillary growth: a case report.

We report the case of an 80-year-old man who presented with pathologically diagnosed chromophobe renal cell carcinoma composed of eosinophilic cells with partial papillary growth. The patient had a 2.5 cm diameter renal mass incidentally detected by abdominal ultrasound examination. Laparoscopic left partial nephrectomy was performed under a diagnosis of left renal tumor. Histopathology demonst...

Review of chromophobe renal cell carcinoma with focus on clinical and pathobiological aspects.

In recent years, the concept of chromophobe renal cell carcinoma (RCC) has been established. Chromophobe RCCs account for about 4-6% of all renal tumors. Macroscopically, the cut surface of the tumor is generally grey-beige in color. Histologically, there are two variants (typical and eosinophilic). In the typical variant, large tumor cells with architecture of a compact tubulo-cystic pattern p...

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...

Incidental Eosinophilic Chromophobe Renal Cell Carcinoma in Renal Allograft

The incidence of renal cell carcinoma (RCC) in renal allograft in transplant recipients is 0.22-0.25%. De novo clear cell, papillary, and chromophobe RCCs and RCCs with sarcomatoid differentiation originating in renal allograft have been reported. Routine surveillance for graft tumours is not routinely practiced and these tumours are commonly asymptomatic and incidentally discovered. We describ...
