ADENOMATOID TUMOR OF THE ADRENAL-GLAND - A REPORT OF 4 NEW CASES AND A REVIEW OF THE LITERATURE

Adenomatoid tumors of the adrenal gland are rare, benign, asymptomatic neoplasms that are usually found incidentally. Previously reported ca ses occurred only in men and only on the left side. We report four cas es, including two from the right adrenal gland, cane from a woman, and one with a cystic component. The average age of our patients was 49 y ears, compared with the average age of 34 years hn previously reported cases, Our immunohistochemical stains and electron microscopic analys is support the presumed mesothelial derivation of these tumors, The di fferential diagnosis of adenomatoid tumors of the adrenal gland includ es a variety of solid and cystic tumors. It is important to recognize these rare tumors to avoid misclassifying them, especially as metastat ic or primary malignant vascular tumors.
