Adrenocortical Adenoma

**Definition:** A benign neoplasm of the ADRENAL CORTEX. It is characterized by a well-defined nodular lesion, usually less than 2.5 cm. Most adrenocortical adenomas are nonfunctional. The functional ones are yellow and contain LIPIDS. Depending on the cell type or cortical zone involved, they may produce ALDOSTERONE; HYDROCORTISONE; DEHYDROEPIANDROSTERONE; and/or ANDROSTENEDIONE.
