Chromophobe renal cell carcinoma with sarcomatoid changes: case report and review of literature
نویسندگان
چکیده
Chromophobe renal cell carcinoma (RCC), a subtype of RCC, accounts for 4-6% of all RCC and has better prognosis then conventional RCC. Sarcomatoid dedifferentiation is thought to represent the high-grade end of all subtypes. This makes chromophobe RCC with sarcomatoid changes a rare entity associated with poor prognosis in most studies. We present a case of a 40-year old female with this rare histology, with the tumour localised to the renal capsule, managed with nephrectomy and with close follow-up thereafter. The patient is free of disease after one year of treatment.

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...

Sarcomatoid component can occur in all histological subtypes of renal cell carcinoma but most commonly accompanies chromophobe renal cell carcinoma. The majority of the sarcomatoid components consist of malignant fibrous histiocytoma, fibrosarcoma or undifferentiated sarcoma areas. Heterologous differentiation in the form of osteosarcoma or rhabdomyosarcoma is very rarely encountered. We report...
