- Primary adrenal lymphoma is extremely rare. Only 75 cases have been reported in the medical literature. A case of non-Hodgkin's lymphoma originating in both adrenal glands is presented. Combination chemotherapy apparently produced complete disappearance of the primary lymphomatous lesions, but subsequently a cerebral relapse was discovered 6 months later, in the form of a solid brain mass. Cranial extension of primary adrenal lymphoma is extremely unusual, and the presentation as a solid mass seems to be unique.
