Dense deposit disease associated with multiple myeloma .

Dense deposit disease (DDD) is a very rare pathological finding associated with activation of the final complement pathway. DDD has been rarely found in association with multiple myeloma (MM). Here we report a patient with MM presenting with renal failure, anemia, and bone pain. The renal biopsy showed DDD. The patient received anti-myeloma treatment and responded well. The case is discussed and literature reviewed.
