PADILLA-FLORES, Juan Roberto et al. Primary Rosai-Dorfman disease of bone. An. Fac. med. [online]. 2021, vol.82, n.1, pp.66-70. ISSN 1025-5583.  http://dx.doi.org/10.15381/anales.v82i1.20785.

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.
