Anterior pituitary gland disorders Pathophysiology
Anterior pituitary: The front portion of the pituitary, a small gland in the head called the master gland. 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. The pituitary regulates and controls the secretion of hormones from other endocrine glands, which in turn regulate many body processes. 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
