Cushing's disease arising from a clinically nonfunctioning pituitary adenoma

摘要

A 49-yr-old woman with a large pituitary tumor leading to visual loss and galactorrhea-amenorrhea was submitted to transcranial pituitary surgery, when a clinically nonfunctioning pituitary adenoma was partially removed. Histopathology and immunohistochemistry confirmed the diagnosis of “non-secreting atypical adenoma”.
