Diagnosis and Treatment of Pituitary Adenomas
Pituitary adenomas are among the most common primary intracranial tumours. They are predominantly benign and account for 10–15 % of all intracranial neoplasms. These tumours are divided into two subgroups: macroadenomas (> 1 cm) and microadenomas (<

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.

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.

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.

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.

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 ...

Pituitary tumors and the risk of other malignancies: is the relationship coincidental or causal?
Pituitary adenomas are benign neoplasms of the pituitary. The most prevalent are prolactinomas and non-functioning pituitary adenomas, followed by growth hormone-and ACTH-secreting 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.

Expressions of Cushing’s syndrome in multiple endocrine neoplasia type 1
Cushing’s syndrome (CS) resulting from endogenous hypercortisolism can be sporadic or can occur in the context of familial disease because of pituitary or extra-pituitary neuroendocrine tumors.
