Although many represent solitary lesions of bone, fewer arise in extraosseous (extramedullary) tissues. We report a case of a primary extraosseous plasmacytoma of the adrenal gland. Magnetic resonance imaging (MRI) with contrast revealed a 3.5-cm, right adrenal mass with heterogeneous enhancement. Although the mass was small and nonfunctioning, concern for malignancy based on MRI findings prompted laparoscopic resection. Histologic and immunohistochemical findings were consistent with a plasmacytoma. This is the third reported case, to our knowledge, of a primary plasmacytoma of the adrenal gland. The present case is unique in that a contrast MRI was performed, which showed heterogeneous enhancement of the mass, providing further evidence beyond heterogeneous hyperintensity on T2-weighted images for a possible malignant process. Another unique feature is that a biopsy specimen of the lesion was taken, although it was nondiagnostic.<\/jats:p>","DOI":"10.5858\/2004-128-e86-eepota","type":"journal-article","created":{"date-parts":[[2021,2,10]],"date-time":"2021-02-10T17:44:04Z","timestamp":1612979044000},"page":"e86-e88","source":"Crossref","is-referenced-by-count":12,"title":["Extraosseous (Extramedullary) Plasmacytoma of the Adrenal Gland"],"prefix":"10.5858","volume":"128","author":[{"given":"Craig G.","family":"Rogers","sequence":"first","affiliation":[{"name":"From the Department of Urology, Brady Urological Institute (Drs Rogers and Pinto) and Department of Pathology (Dr Weir), Johns Hopkins Hospital, Baltimore, Md.
