Non-Hodgkin's lymphoma involving a femur bone and bilateral adrenal glands alone with adrenal insufficiency

Primary bone lymphoma and primary adrenal lymphoma are rare clinicopathological entities of non-Hodgkin9s lymphoma (NHL). We present the first case of diffuse large B-cell lymphoma with the involvement of a single bone and both adrenal glands alone with adrenal insufficiency. As primary extranodal NHL may have other unusual extranodal lesions, which may present unexplained clinical findings, patients with primary extranodal NHL require careful systemic examination, even when lymphadenopathy is absent.
