Mucinous adenocarcinoma of the renal pelvis--a case report.

A case of mucinous adenocarcinoma of the renal pelvis is added to those so far reported. Association with long standing chronic infection and large renal calculi is emphasized. The occult gross appearance of most of these tumours may lead the pathologist to overlook their presence. Hence, any kidney with the proper setting must be carefully looked for this entity.
