title: Primary lymphoma of the calcaneus.
abstract: Primary non-Hodgkin's lymphoma (NHL) of bone is a rare condition. Presented herein is a case of primary NHL of the calcaneus illustrating many of the classic features of the disease. Emphasized in this report are the nonspecific clinical and conventional radiographic features of primary NHL of bone, which may mimic inflammatory, neuropathic, infectious, or other neoplastic conditions of the extremities. The importance of early cross-sectional radiologic studies, such as magnetic resonance imaging, lies in the early characterization of the mass-like features and local extent of such lesions, helping to raise the suspicion of neoplastic disease.
