Background Pituitary carcinomas are rare neuroendocrine tumors affecting the adenohypophysis. The hallmark of these lesions is the demonstration of distant metastatic spread. To date, few well-documented cases have been reported in the literature.

Aggressive pituitary tumors (PitNETs).
The majority of anterior pituitary tumors behave benignly, that is, they grow slowly and do not metastasize, and were therefore called adenomas. However, they would frequently invade adjacent structures, leading to recurrence.

No evidence for oncogenic mutations in guanine nucleotide-binding proteins of human adrenocortical neoplasms [PDF]
G-Proteins are membrane-bound heterotrimeric polypeptides that couple receptor signals to second messenger systems such as cAMP. Recently, point mutations at 2 codons of the highly preserved alpha-chain of Gs, the adenyl cyclase-stimulating G-protein ...

Pituitary metastases as a rare variant of intracranial metastasis
Metastatiс spread of neoplasms to the pituitary gland is a relatively common finding in autopsy series of cancer patients. The majority of these patients were asymptomatic.

Simple Summary Pituitary adenomas are highly prevalent intracranial neoplasms that can be locally invasive in up to half of cases. Consequently, using the term “PitNETs” (pituitary neuroendocrine tumors) instead of pituitary adenoma is recommended to ...

Coexisting intracranial tumors with pituitary adenomas: Genetic association or coincidence? [PDF]
The co-occurrence of two or more brain tumors with different histological features is rare. The authors report three rare cases of intracranial tumors associated with pituitary adenomas.

Resistant prolactinoma: Is it monoclonal or polyclonal?
Prolactinomas are solitary benign neoplasms and resistance to dopamine agonists occur in a small percentage of prolactinomas. Multiple pituitary adenomas are reported in less than 1% of pituitary adenomas and rarely result in resistant prolactinoma.

The FGFR4-G388R polymorphism promotes mitochondrial STAT3 serine phosphorylation to facilitate pituitary growth hormone cell tumorigenesis. [PDF]
Pituitary tumors are common intracranial neoplasms, yet few germline abnormalities have been implicated in their pathogenesis. Here we show that a single nucleotide germline polymorphism (SNP) substituting an arginine (R) for glycine (G) in the FGFR4 ...

A retrospective analysis of postoperative hypokalemia in pituitary adenomas after transsphenoidal surgery [PDF]
Background Pituitary adenoma is one of the most common intracranial neoplasms, and its primary treatment is endoscopic endonasal transsphenoidal tumorectomy.
