Abstract
We herein report a case of multiple myeloma diagnosed due to persistent hemorrhage after tooth extraction. A 75-year-old woman sought medical attention at our hospital on August 19, 2003, for incompatibility sensations in the maxillary molar region. Bleeding time was confirmed since past medical history revealed persistent hemorrhage after tooth extraction at her former dental clinic. Laboratory data revealed prolonged bleeding time, prothrombin time and activated partial thromboplastin time. After bilateral maxillary molars and left lateral mandibular incisor were extracted, persistent bleeding from right maxillary molar area was noted. Additional examination by the staff of the internal medicine department revealed elevated immunoglobulin A, and increase of plasma cells was demonstrated with bone marrow aspiration. Therefore, diagnosis of IgA type myeloma was made. The deficit of bone in the right maxillary molar area was confirmed with computed tomography. Clinical course and the results (findings) of the examination suggested that the myeloma of the right maxillary molar area resulted in persistent (hemorrhage) bleeding after tooth extraction.
