title: Lymphoplasmacytoid lymphoma presenting as severe osteoporosis.
abstract: We report four cases presenting with severe osteoporosis which on further investigation were found to have an underlying lymphoplasmacytoid lymphoma (LPL). Common secondary causes of osteoporosis were excluded in each case. Three of the cases responded to treatment with a biphosphonate. As these lymphomas share some common pathological and clinical features with multiple myeloma (MM) an association with osteoporosis is likely to represent more than a coincidental finding. The incidence of osteoporosis occurring with LPL will become clearer if routine imaging is carried out in patients at presentation. Issues relating to the treatment of the osteoporosis as well as the lymphoma arise in patients that present in this way. Based on the model of bone disease in MM, correlating serum levels of osteoclast activating cytokines such as interleukin-1 (IL-1), interleukin-6 (IL-6), and tumour necrosis factor (TNF) with the actual finding of bone disease provides a basis for future research into the pathogenesis and management of bone disease in these rare forms of low grade non-Hodgkin's lymphoma.
