Adenomatoid Tumor of the Right Adrenal Gland in a Patient with AIDS.

An autopsy case with an incidentally discovered adenomatoid tumor (AT) arising in the right adrenal gland of a 34-yr-old man with AIDS is presented. The immediate cause of death was disseminated coccidioidomycosis. The affected right adrenal gland was partially substituted by a firm 3.O cm nodule enclosed by cortical adrenal tissue. Histologically, the tumor had the typical appearance of those adenomatoid neoplasms described in the genital tract. The mesothelial origin of the neoplasm was confirmed by immunopositive cells for low weight cytokeratin and vimentin. Uncommon neoplasms in the adrenal glands of AIDS patients include leiomyosarcomas, leiomyomas, and malignant nerve sheath tumors. This report may represent the first case of an adrenal gland AT in a patient with AIDS, and probably the third well-documented histologically and immunohistochemically adrenal gland AT.
