[Multiple myeloma with oral manifestations--report of two cases].
Multiple myeloma is a neoplastic disorder of bone that originates from cells of bone marrow. It is most commonly seen within the age range of 50-80 years, cases under the age of 40 being rare. Men are affected more frequently than are women. Bone pain is the cardinal clinical symptom in multiple myeloma. Because of the destruction of bone, pathologic fracture is fairly common. In the oral manifestations, the mandible is involved far more frequently than the maxilla, especially the most active hematopoietic areas-the remus, angle and molar region of the mandible. Other signs and symptoms of jaw involvement include swelling, pain, and increased tooth mobility. Extraosseous lesions may result in paresthesia of soft tissue and gingival enlargement with bleeding tendency. Roentgenographic examination will usually reveal numerous punched-out lesions in a variety of bones. In addition, blood examination will reveal hyperglobulinemia and Bence-Jones protein may be present in the urine of myeloma patients. The histological features of myeloma are closely packed cells resembling plasma cells. Case 1 in this report is a 64-year-old female, who has been diagnosed as having multiple myeloma (IgG, lambda). She was referred to our hospital because of gingival swelling, bleeding and pain. Case 2 is a 60-year-old female suffering from spontaneous gingival bleeding. After blood, urine examination and bone marrow biopsy, multiple myeloma was diagnosed (IgG, lambda). This paper reports the clinical manifestations and treatment courses of these two cases, and the concerns of treatment of multiple myeloma are also discussed.
