Aggressive Pituitary Tumors [PDF]
Pituitary adenomas are common intracranial tumors that are mainly considered as benign. Rarely, these tumors can exhibit an aggressive behavior, characterized by gross invasion of the surrounding tissues, resistance to conventional treatment leading to early and frequent recurrences.

Surgical Complications of Endoscopic Endonasal Trans-Sphenoidal Approach for Pituitary Tumors [PDF]
Background: Pituitary macro-adenomas form about 10% of intracranial tumors. Most of them are non-functioning and manifestations are due to space-occupying effects or clinical hypo-pituitarism.

The Epigenomics of Pituitary Adenoma
Background: The vast majority of pituitary tumors are benign and behave accordingly; however, a fraction are invasive and are more aggressive, with a very small fraction being frankly malignant.

Pituitary tumors and the risk of other malignancies: is the relationship coincidental or causal?
Pituitary adenomas are benign neoplasms of the pituitary. The most prevalent are prolactinomas and non-functioning pituitary adenomas, followed by growth hormone-and ACTH-secreting adenomas.
