Myelomatosis (IgD, lambda) discovered by oral manifestation

A 49-year-old male patient with diffuse myeloma is reported. Although obvious punched-out radiolucency is frequently seen in multiple myeloma, in this case it was not observed, with only a faint resorption of the alveolar ridge being noticed. It is emphasized that a biopsy, radiographic examination and other laboratory findings are necessary to diagnose this disease.
