[Mucinous cystadenoma of the kidney].

Mucinous tumors of the kidney are rare. The pathogenesis of these lesions is controversial. We report the observation of a 31-year-old woman presented with right-flank pain and hematuria. Abdominal ultrasonography and computed tomography revealed a multicystic mass of the right kidney. A total nephrectomy was performed. The pathological exam concluded on a mucinous cystadenoma of the right kidney. Mucinous cystadenoma of the kidney with a multicystic presentation has not been previously reported. In this work, we present the different pathogenic hypothesis and the means of treatment of this rare entity.
