A Case of Deep Neck Abscess That Was Diagnosed as Having Waldenström’s Macroglobulinemia

Waldenström’s macroglobulinemia (WM) is a distinct clinicopathologic entity characterized by the presence of lymphoplasmacytic lymphoma (LPL) in the bone marrow and IgM monoclonal gammopathy in the blood, with diverse clinical presentations, including cytopenias linked to bone marrow infiltration, hyperviscosity syndrome, fever, lymphadenopathy, and recurrent infections. We report a case of a patient who was diagnosed as having WM after he presented with a deep cervical abscess, which resulted in death.
