10% of all intracranial neoplasms are pituitary tumors.

Benign adenomas are most common

The most common pituitary adenoma is microadenoma and about70% microadenomas are prolactinoma.

Cellular monomorphism and absence of significant retificant reticulin network distinguishes pituitary adenomas from nonneoplastic anterior pituitary parenchyma.
