title: Malignant lymphoma masquerading as multiple myeloma.
abstract: A case of non-Hodgkin's lymphoma with features mimicking that of multiple myeloma is reported. A 67-year-old man presented with lymphadenopathy and the classic constellation of symptoms and signs of multiple myeloma, including generalised bone pain, hypercalcemia and multiple osteolytic lesions on the skeletal survey. However, cervical lymph node biopsy showed diffuse large cell lymphoma and marrow aspirate showed infiltration with lymphoma cells different in both morphology and surface markers to myeloma cells.
