Clinical Course of a Patient With Kidney Failure Due to Isolated Bilateral Renal Extramedullary Plasmacytomas

Plasmacytomas are rare immunoproliferative monoclonal plasma cell diseases of lymphoid lineage that may present in an isolated or systemic manner. Systemic involvement is much more common than occurrences isolated to a particular organ, and for this reason, it is imperative to rule out systemic involvement for osseous and nonosseous isolated neoplasms. These neoplasms present unique challenges due to their location, extent of involvement, vague presentation, and dearth of treatment protocol. We report the case of a 69-year-old man who developed chronic kidney disease stage 4 between 2009 and 2012.
