Introduction Pituitary tumors are invariably benign neoplasms identified in ∼25% of unselected autopsy specimens, and may cause considerable morbidity due to excess hormone secretion and/or compression of surrounding brain structures ( Melmed 2003

Introduction Pituitary adenomas are indolent tumors, which account for 10–15% of all diagnosed intracranial neoplasms ( Asa & Ezzat 2002 , DeLellis et al. 2004 ). Small adenomas may occur in up to 15% of pituitary glands examined

Introduction Anterior pituitary tumors are usually benign neoplasms that derive from the endocrine cells of the anterior pituitary gland. However, a small percentage of them have an aggressive behavior, showing resistance and/or multiple

Introduction Pituitary tumors are generally benign adenomas. Radiology and autopsy, being performed for reasons other than pituitary-related medical ones, show a high prevalence of 10–15% in the overall population, although most of these lesions are

Since the early work of Minkowski, who attributed acromegaly to a pituitary tumor ( Minkowski 1887 ), neoplasms composed of pituitary adenohypophysial cells have been recognized as the cause of significant illness. However, Harvey Cushing

Introduction Pituitary tumors, accounting for 16.2% of all primary brain and other central nervous system tumors ( Ostrom et al. 2017 ), are classified based on their secretory activity in non-functioning pituitary tumors (NFPTs) or hormone

Introduction Pituitary tumor transforming gene (PTTG1), the index mammalian securin, was isolated from rat pituitary tumor cells ( Pei & Melmed 1997 ), and the human homolog (hPTTG1) was identified as a proto-oncogene ( Zhang et al . 1999 b
