Hormones secreted by the anterior pituitary influence growth, sexual development, skin pigmentation, thyroid function, and adrenocortical function. A major organ of the endocrine system, the anterior pituitary (also called the adenohypophysis or pars anterior), is the glandular, anterior lobe that together with the posterior lobe (posterior pituitary, or the neurohypophysis) makes up the pituitary gland (hypophysis). (Oxford University Press, 2015) Etiology The pituitary gland is a grape-sized endocrine gland located at the base of the brain.

These hormones include the following: Growth hormone (GH) Thyroid-stimulating hormone (TSH) Adrenocorticotrophic hormone (ACTH) Prolactin About 75% of pituitary tumors secrete hormones. When a tumor produces excessive amounts of one or more hormones, the following conditions may occur: Giantism or acromegaly (excess growth hormone), Hyperthyroidism (excess thyroid stimulating hormone), Cushing 's syndrome (excess adrenocorticotropic hormone) and Prolactinoma (excess prolactin). As the tumor grows, destruction of some of
