Which of the following pathophysiologic phenomena may result in a diagnosis of Cushing disease?
A) Hypopituitarism
B) Excess ACTH production by a pituitary tumor
C) Autoimmune destruction of the adrenal cortex
D) Malfunction of the HPA system
Ans: B
Feedback:
Three important forms of Cushing syndrome result from excess glucocorticoid production by the body. One is a pituitary form, which results from excessive production of ACTH by a tumor of the pituitary gland. Hypopituitarism and destruction of the adrenal cortex are associated with Addison disease. Disruption of the HPA system is not implicated in the etiology of Cushing disease.
