Molecular and cellular pathogenesis of pituitary tumors
(Elsevier, 2018-08)
Pituitary tumors occur sporadically (95%) or as hereditary tumors, either associated with endocrine syndromes (2.5%) or as familial isolated variants (FIPA, 2.5%). In sporadic pituitary tumors, in addition to the known ...
Pituitary tumor apoplexy
(Academia Brasileira de Neurologia - ABNEURO, 2009-06-01)
Pituitary tumor apoplexy is a medical emergency due to acute infarction or hemorrhage in the pituitary gland. In this review, the authors discuss the sellar anatomy, the pituitary gland and adenomas' vascularization and ...

Extremely late development of pituitary carcinoma after surgery and radiotherapy
(SPRINGER, 2009)
Introduction Pituitary carcinomas account for 0.1 or 0.2% of pituitary tumors. The authors report a rare case of a pituitary carcinoma mimicking a radio-induced meningioma. Case report Fifty-five years-old male presents a ...
Pituitary Apoplexy After a Single Dose of Long-Acting Octreotide
(Lippincott Williams & Wilkins, 2010-01-01)
Pituitary apoplexy (PA) is a rare and potentially life-threatening syndrome resulting from an acute infarction or hemorrhage of the pituitary gland. Although the pathogenesis is not fully understood, some predisposing ...

Adrenocorticotropin-producing pituitary carcinoma with expression of c-erbB-2 and high PCNA index: A comparative study with pituitary adenomas and normal pituitary tissues
(Humana Press Inc, 1998-03-01)
Pituitary carcinomas are very rare neoplasms with a poor prognosis. We report a case of Cushing's disease resulting from a pituitary carcinoma in a ZZ-yr-old female, who died of massive hepatic failure. At autopsy, there ...
Programmed cell senescence: Role of IL-6 in the pituitary
(BioScientifica, 2017-05)
IL-6 is a pleiotropic cytokine with multiple pathophysiological functions. As a key factor of the senescence secretome, it can not only promote tumorigenesis and cell proliferation but also exert tumor suppressive functions, ...
Changes of stem cell niche during experimental pituitary tumor development
(Wiley Blackwell Publishing, Inc, 2021-10)
To investigate the putative stem cell/tumor stem cell (SC/TSC) niche contribution to hyperplasic/adenomatous pituitary lesions, we analyzed variation in the pituitary stem cell population during the development of experimental ...
