IgA . K type myeloma with severe postextraction bleeding.
A case of multiple myeloma detected by the first symptom of severe postextraction bleeding was presented. Although laboratory data showed severe anemia, rouleaux formation of erythrocytes, abnormal hemostatic parameters, elevated erythrocyte sedimentation rate and hyperglobulinemia, no involvement of bones such as the jaws, skull, ribs or sternum was demonstrated roentgenologically. Final diagnosis obtained by immunoelectrophoresis was Ig A . K type myeloma. During a therapeutic period with melphalan and predonine, bleeding from the extracted wound was repeated. 2 months after the onset of the first symptoms, the patient died of systemic bleeding. Autopsy findings revealed many hemorrhagic sites in the lungs, stomach, kidney and bladder and the existence of plasma cell-like tumor cells in the bone marrow of lumber vertebra and sternum.
