title: [Retroperitoneal mass secondary to Bellini carcinoma].
abstract: Bellini Collecting Duct carcinoma is a rare and aggresive histological variety of renal adenocarcinoma which originates from the epithelium of the collecting tubule, with a well established histological, cytogenetic and inmunohistochemic characterization. It allows us to differenciate this tumor type from the rest of renal adenocarcinomas. There are 7 cases already published in the national literature. We introduce a new case with a particularity that is to show an unusual presentation form. It appears clinically without a specific urological symptomatology and radiologically it present a retroperitoneal mass shape with explains the patient's clinical manifestations.
