Multicentric papillary and chromophobe renal cell carcinomas in a patient with autosomal dominant polycystic kidney disease: Report of a rare case

Abstract

The causal relationship of autosomal dominant polycystic kidney disease (ADPKD) with the development of renal cell carcinoma (RCC) is still not known. We describe a case of bilateral PKD complicated with a large enhancing mass and multiple small nodules in the left kidney. The histopathological study of the nephrectomy specimen revealed the synchronous occurrence of eosinophilic variant of chromophobe RCC (EVCRCC) and multicentric papillary RCC (PRCC) in a background of ADPKD. To the best of our knowledge, this case is the first to describe the collision tumor of EVCRCC and multicentric PRCC in ADPKD.
