The normal adrenal gland contains two types of tissue, the adrenal cortical tissue and the adrenal medullary tissue. The cortex is divided into three portions: the outermost "zona glomerulosa," the central "zona fasciculata," and the innermost "zona recticularis." The adrenal medulla is a developmentally separate organ, derived from neuroectoderm, and is the site of epinephrine and norepinephrine production. Adrenal cortical adenoma is commonly the result of a basophilic tumor of the anterior pituitary that secretes excessive amounts of ACTH. Adrenal medullary hyperplasia (or pheochromocytoma) are clinically hazardous tumors because of their excessive secretion of catecholamines. Combined adrenal cortical adenoma and adrenal medullary hyperplasia of the right adrenal gland has never been described previously.
正常肾上腺包含两种组织，即肾上腺皮质组织和肾上腺髓质组织。皮质分为三个部分：最外层的“球状带”、中间的“束状带”和最内层的“网状带”。肾上腺髓质是一个在发育上独立的器官，起源于神经外胚层，是肾上腺素和去甲肾上腺素产生的部位。肾上腺皮质腺瘤通常是垂体前叶嗜碱性肿瘤分泌过量促肾上腺皮质激素的结果。肾上腺髓质增生（或嗜铬细胞瘤）因其过量分泌儿茶酚胺而成为临床上有危险的肿瘤。右肾上腺的肾上腺皮质腺瘤合并肾上腺髓质增生此前从未有过描述。
