Multilocular Cystic Nephroma of the kidney in a young adult: case report

Abstract

We report the case of a 20-year-old female patient who presented with a left abdominal mass of 4 years duration. Ultrasonography showed a multicystic left renal mass, and intravenous urography revealed a non-functioning kidney. Based on these findings a multicystic renal cell carcinoma was suspected and radical nephrectomy was performed. Histological examination of the resected specimen confirmed the diagnosis of multilocular cystic nephroma. This is a very rare renal tumor with only few cases described in the literature. Based on our case and a review of the literature the epidemiology, pathogenesis and diagnostic features are discussed.

Key Words: Cystic nephroma, renal cell carcinoma, kidney
