[Relapse of multiple myeloma in extramedullary sites]

Multiple myeloma was diagnosed in a 69-year-old man with pathological hip fracture, who had increased plasma cells in the bone marrow, osteolytic lesions in bones, low level of monoclonal protein (IgAK) in serum and urine, and anemia, hypercalcemia and renal insufficiency. He was treated for 1 year with chemotherapy with good results. 6 months after cessation of treatment the disease relapsed with multiple extramedullary plasmacytomas in skin and subcutaneous areas, right eyebrow, right knee, sternum and right axilla, but repeated bone marrow examinations were without evidence of disease activity. Chemotherapy was resumed but the patient died 1.5 years after the relapse with severe jaundice due to multiple liver plasmacytomas and pelvic masses.
