ACTH-secreting tumor
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]
Overview
An ACTH secreting tumor is a type of pituitary adenoma which produces ACTH.
Pathophysiology
The tumor stains basophilic on pathologic examination. The excess production of ACTH by the tumor results in Cushing's syndrome.
Diagnosis
Pituitary adenomas may grow and compress adjacent structures, most commonly causing a bitemporal hemianopsia due to compression of the optic chiasm. Lateral extension into the cavernous sinuses can result in cranial nerve palsies.
