A adrenal adenoma is a benign tumor of the glandular type (adenoma) in the adrenal gland. While some adrenal adenomas do not secrete hormones at all (nonfunctional often diagnosed incidentally as incidentalomas) some secrete cortisol (causing Cushing’s syndrome) aldosterone (causing Conn’s syndrome) or androgens (causing hyperandrogenism).
