Ipsilateral Synchronous Renal Cell Carcinoma: Papillary and Chromophobe

Abstract

Synchronous renal tumors are the general name of multiple tumors with bilateral or unilateral location which are less frequently seen. Here, we present a case of papillary renal cell carcinoma (pRCC) and chromophobe renal cell carcinoma (chRCC) as a rare entity in a single kidney. A 41-year-old woman underwent a radical nephrectomy for a mass with an 11 cm diameter localized in the lower left pole. Macroscopic examination revealed a 10.5x9.5 cm sized tumor and one more tumor 1 cm away from this tumor sized 1.7x1.2 cm. The histopathological and immunohistochemical features of the two tumors were evaluated and were diagnosed as chRCC and pRCC. Synchronous renal tumors are rare. Generally one component of renal synchronous tumors reported in the literature is usually clear cell renal cell carcinoma, which is the most frequently seen renal cell carcinoma type of all. We present this case because of it's uniqueness.
