Diffuse Kidney and Retroperitoneal Infiltration by Plasmablastic Myeloma

Abstract

Plasmablatic cell myeloma is a rare but aggressive form of multiple myeloma (MM) with a poor survival. Extramedullary localization of plasmablastic myeloma may be observed in more than two-thirds of patients mainly in the upper digestive tract. Herein, we report the first case of plasmablastic MM leading to acute kidney injury through renal and ureteral infiltration.
