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 fasciculate� 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.

    Our previous study showed that the mutation hotspots of the K-ras proto-oncogene in human functional adrenocortical tumors are in codons 15, 16, 18, and 31, thus differing from the sites in other tumors. In addition, analyzing the K-Ras protein by a recombinant DNA technique showed that the...
