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.

KI-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. Generally, pituitary tumors behaving aggressively have increased Ki-67 labeling indices.

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)
Neurosurgery, 2010Several 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 ...

Pituitary Neoplasms in two Horses
Zentralblatt für Veterinärmedizin Reihe A, 1963SummaryTwo pituitary adenomas in older geldings are described: a chromophobe adenoma with severe acute hemorrhages among the neoplastic cells and an adenoma originating from the pars intermedia with a lesser degree of disseminated recent hemorrhages. Invasiveness was not observed, but, both tumors caused hemorrhages and pressure in the hypothalamic ...

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 lesions may produce if they expand upward to an unusual size.

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.

Pituitary adenoma or neuroendocrine tumour: the need for an integrated prognostic classification
Nature Reviews Endocrinology, 2023This Perspective presents the outcomes of an interdisciplinary international workshop that addressed the implications of the WHO classification change of pituitary adenoma to neuroendocrine tumours. The authors propose that a comprehensive classification

Pituitary Neuroendocrine Neoplasms
2020Pituitary neuroendocrine tumors are a complex family of lesions that show a spectrum of differentiation based on their developmental regulatory transcription factors and hormone expression. They can cause a number of clinical syndromes such as acromegaly, Cushing disease, hyperprolactinemia, and hyperthyroidism or they may be clinically silent.
