We report a 72-year-old man with Waldenström's macroglobulinemia (WM) in whom diffuse large B-cell lymphoma (DLCL) occurred 17 years after the diagnosis of WM. The malignant cells of both DLCL and WM expressed CD20 on their surface. CHOP plus anti-CD20 monoclonal antibody, rituximab, were effective for both diseases, and the patient remains disease-free 17 months later.
