Rosai-Dorfman disease is a rare pathology that usually presents as painless cervical adenopathies. Bone compromise as an extra nodal presentation is even more uncommon. We present the case of a 38 years old woman with a 3 months history of pain and functional limitation of her right lower limb. X-ray and CT images showed a lytic bone lession at the distal metaphysis and epiphysis on her right femur. Histological and immunohistochemical study of the lession determined that it was a case of Rosai-Dorfman disease with bone involvement.
