Epithelial-lined (true) cyst of the adrenal gland: A case report
Abstract
A case of an epithelial-lined (true) adrenal cyst is reported. Although over 300 adrenal cysts have been reported in the literature, true cysts are rare. In this case, a 4.0 cm cyst lined by cuboidal to flattened cells with bland cytologic features was incidentally found at autopsy. Immunologic studies performed on formalin-fixed, paraffin-embedded sections demonstrated that the cells expressed keratins ( AE1 AE3+, CAM 5.2+, and MAK-6+) and were negative for epithelial membrane antigen, vimentin, factor VIII, and desmin. Normal adrenal cortical and medullary cells did not express keratins, suggesting that the cyst lining was not derived from either adrenal cortex or medulla. A mesothelial origin, with a pathogenesis analogous to the formation of primary cysts of the spleen, is proposed. © 1989.
