Myeloma cells in the urine.
We report two unusual manifestations of multiple myeloma in a 71-year-old man. Late in the course of his disease, myeloma cells were observed in the patient's urinary sediment. At post mortem, the source of the cells was found to be a plasmacytoma of the urinary bladder. To our knowledge, this appears to be the first report of a clearly demonstrable anatomic source for myeloma cells in the urine.
