title: Simultaneous occurrence of two B-cell malignancies: A case report.
abstract: The present study describes the case of a 75-year-old male with coexisting multiple myeloma and diffuse large B-cell lymphoma. Although the two malignancies are mature B-cell neoplasms, their clinical manifestations are very different and the clinical approaches used to treat these two types of tumor vary. The patient in the present case was diagnosed with the simultaneous existence of two different B-cell tumors and was successfully treated using the DCEP regimen. The simultaneous presentation of two mature B-cell neoplasms, types of hematological malignancy, is very rare, thus the present case is considered to be interesting.
