Final answer:
Hyperadrenocorticism, or Cushing's syndrome, is characterized by the excessive production of cortisol, often due to a pituitary tumor. It presents with various symptoms including obesity, hypertension, and specific skin changes. Treatment is tailored to the underlying cause.
Step-by-step explanation:
Hyperadrenocorticism (HAC), commonly known as Cushing's syndrome, is a condition resulting from the hypersecretion of the glucocorticoid hormone cortisol. This can be due to various underlying causes, including a pituitary tumor leading to excessive production of adrenocorticotropic hormone (ACTH), which in turn stimulates the adrenal cortex. Cushing's syndrome can manifest in a range of symptoms such as obesity, diabetes, hypertension, excessive body hair, osteoporosis, and depression. A distinctive feature of the syndrome is the thinning of the skin, accompanied by stretch marks, as well as the development of a moon face and a buffalo hump. Treatment depends on the underlying cause but may involve surgical removal of a tumor or medication to suppress adrenal function.
