Temporomandibular arthritis as the initial symptom of IgD multiple myeloma：a case report

Abstract

Multiple myeloma （MM） is a malignant plasma cell disease with bone pain， renal insufficiency， anemia and hypercalcemia as the main symptoms. It is likely to be misdiagnosed and missed diagnosis because of complex clinical manifestations. MM with temporomandibular arthritis as the initial symptom is rare. In this article， the diagnosis and treatment of one case of IgD MM with temporomandibular arthritis as the initial symptom were reported. The 48-year-old male patient presented with pain and numbness in the right temporomandibular area as the initial symptoms. He was admitted to different local hospitals. Imaging examination was highly indicative of MM， which was eventually confirmed by bone marrow aspiration and immunofixation electrophoresis. This case prompts that clinicians should deepen the understanding of MM， especially IgD MM that is relatively difficult to diagnose， aiming to lower the risk of misdiagnosis and missed diagnosis.
