Plasmacytomas are monoclonal plasma cells proliferations originating either in localized osseous tissue or in soft tissue (extramedullary plasmacytoma, EMP). Although many such lesions are found in the bone marrow, fewer arise in extramedullary tissue. A solitary EMP involving the adrenal gland is extremely rare, with only 7 cases having been reported in the literature thus far. Here, we describe a rare case of solitary EMP in the right adrenal gland of a 26-year-old man that was managed by retroperitoneal laparoscopic resection, with no recurrence during 6-year follow-up.
