Skeletal involvement in patients with non-Hodgkin's lymphoma (NHL) is not u
nusual, but relatively few cases with peripheral joint involvement have bee
n reported(1-12). We describe a patient with NHL diagnosed on the basis of
cytologic examination of synovial fluid (SF) that we believe is the first r
eported case of NHL synovitis in association with human immunodeficiency vi
rus (HIV) infection.
