Solitary Renal Plasmacytoma with Palisading Tumor Vascularity

Abstract

A solitary extramedullary plasmacytoma of the kidney associated with contralateral myeloma kidney is reported. The tumor demonstrated extensive palisading tumor vessels, heretofore thought to be characteristic of renal lymphoma. Plasmacytoma as the etiology of a renal mass should be considered when there is nonfunction of a normal-appearing contralateral kidney.
