Objective:
To present a case of extramedullary plasmacytoma localized in the kidney. The clinical features, diagnostic tests, treatment and outcome are discussed.
Methods/Results:
A 59-year-old patient presented with a right renal mass and renal failure. The complementary tests showed a lambda monoclonal band in blood and urine, and a left renal biopsy showed changes compatible with myeloma. The definitive diagnosis of plasmacytoma was based on the findings of open renal biopsy since fine needle punction findings were compatible with a carcinoma. The patient received polychemotherapy, but died one year after the diagnosis due to a rapidly progressing plasmatic cell dyscrasia.
Conclusion:
Renal plasmacytoma is rare and should be suspected when paraprotein is detected in blood and urine, and when the patient has a history of plasmatic cell dyscrasia. There is no widely-established treatment. Surgery, radiotherapy or chemotherapy, alone or in combination, can be utilized.
