Brain Tumor Pathology, 2021
In 2017, WHO published an updated classification of the pituitary adenomas according to the lineages defined by the transcription factors, PIT1, SF1 and TPIT. Nomenclature of the pituitary tumors follows the mature cell types such as somatotroph (GH), lactotroph (LH), thyrotroph, corticotroph, and gonadotroph (FSH, LH).

Biomarkers of Pituitary Neoplasms: A Review (Part II) [PDF]
Neurosurgery, 2010 Several new markers have shown a capacity to predict the clinicopathological behavior of pituitary neoplasms; these markers have shown potential to correlate with tumor subtype and size and patient age and sex. These various markers are involved in a host of cellular functions, including cell-cycle progression, cell proliferation, apoptosis, cell ...

Ki-67 in pituitary neoplasms: a review--part I.
Neurosurgery, 2009KI-67, A MARKER of cellular proliferation, has been studied extensively in pituitary neoplasia. It is of relevance to various clinicopathological parameters, including tumor subtype, size, invasiveness, and recurrence, as well as patient age and sex ...

Psychological changes associated with giant pituitary neoplasms.
Archives of Neurology And Psychiatry, 1955Although nearly 600 articles concerning pituitary adenomas and craniopharyngiomas have been listed in the Quarterly Cumulative Index Medicus since its first volume, in 1916, only 13 are primarily concerned with the psychological changes which these ...

Pituitary Neoplasms in two Horses
Zentralblatt für Veterinärmedizin Reihe A, 2010Summary Two pituitary adenomas in older geldings are described: a) a chromophobe adenoma with severe acute hemorrhages among the neoplastic cells and b) an adenoma originating from the pars intermedia with a lesser degree of disseminated

Ultrastructure of spontaneous pituitary neoplasms in the rat.
Journal of Comparative Pathology, 1980Abstract Spontaneous pituitary neoplasms of 19 old Sprague-Dawley rats were examined by electron microscopy. The ultrastructure suggested that the chromophobe adenomata were derived mainly from mammotropic cells and that they were functionally active.

Immunohistochemical expression of nestin in the non-tumorous hypophysis and in pituitary neoplasms
Acta Neuropathologica, 2006The aim of the present work was to investigate whether nestin, a member of the intermediate filament family, is immunohistochemically expressed in the non-tumoral human hypophysis and pituitary neoplasms. Twenty-three normal pituitaries and 125 pituitary neoplasms were included. The tissues were formalin-fixed and paraffin embedded.

A proposed clinical classification for pituitary neoplasms to guide therapy and prognosis.
The Lancet Diabetes & EndocrinologyNo comprehensive classification system that guides prognosis and therapy of pituitary adenomas exists. The 2022 WHO histopathology-based classification system can only be applied to lesions that are resected, which represent few clinically significant pituitary adenomas.

Diagnosis and Management of Pituitary Adenomas: A Review.
Journal of the American Medical Association (JAMA), 2023Importance Pituitary adenomas are neoplasms of the pituitary adenohypophyseal cell lineage and include functioning tumors, characterized by the secretion of pituitary hormones, and nonfunctioning tumors.
