Osteomalacia of renal origin revealing a Sjogren's syndrome. Latent renal tubular diseases are common in Sjogren's syndrome but rarely complicated by osteomalacia. The authors report a 28 years old woman's case where osteomalacia reveal the disease. In the other hand, a pseudo-lymphoma is suspected from radiographic features. According to several studies, the authors review different types of renal diseases and describe different physiopathological hypotheses about bone involvement and pseudo-lymphomas.
