Adrenal Medullary Hyperplasia

Abstract

Endocrine gland hyperfunction is usually associated with its hyperplasia or tumor. Pertaining the adrenal medulla it is well known clinical presentation of pheochromocytoma, but there is still some doubt on clinical significance of adrenal medullary hyperplasia. It has been reported that patients with adrenal medullary hyperplasia may display symptoms suggesting pheochromocytoma. Several authors have suggested that adrenal medullary hyperplasia is a precursor condition to the development of pheochromocytoma. However, very rarely may be a sporadic disease.
