Abstract

Multiple myeloma (MM) is a relatively uncommon oncohematological condition characterized by abnormal proliferation of plasma cells. Oral manifestations of MM can occur in soft and intraosseous parts. We present a case of a 69-year-old man diagnosed with MM and undergoing chemotherapy, referred to the dental service complaining of a nodular swelling in the maxilla. An incisional biopsy was conducted and the histopathological analysis showed a monoclonal proliferation of plasma cells with a positive CD 138 immunophenotype, which allowed the diagnosis of extramedullary plasmacytoma. The outcome of the case was unfavorable and the patient died. We emphasize the importance of diagnosing MM extramedullary disease in the maxillofacial region.
