title: Skeletal lymphoma.
abstract: The records of forty-two patients with lymphoma of bone [.11 with Hodgkin disease (HD), 31 with non-Hodgkin lymphoma (NHL)] were retrospectively reviewed to correlate histologic type with sites of osseous involvement, radiographic patterns of bone destruction, and prognosis. The vertebral column was the most frequent site of axial involvement and the femur was the commonest site overall. In HD, the most frequent radiographic pattern was vertebral sclerosis, while periosteal reaction was noted in two focal femoral lesions and hypertrophic pulmonary osteoarthropathy in one patient. In NHL, permeative destruction predominated, while unusual layered periosteal reaction and eccentric cortical destruction were each seen in two patients. Radiographic patterns of bone involvement alone cannot be used to predict histologic type or prognosis. Staging remains the most important prognostic indicator. For skeletal lymphoma, instead of the traditional Ann Arbor Staging System, we prefer the more specific Mayo Staging System which relates the temporal appearance of osseous disease to nodal or soft-tissue disease or both.
