Original Source: AIP Mutation in Pituitary Adenomas.
To the Editor: Chahal et al. (Jan. 6 issue)(1) describe four families with familial isolated pituitary adenomas who had the same mutation as an 18th-century giant.(2) They conclude that the old theory that considered gigantism to be a congenital disorder, whereas acromegaly was considered to be acquired in adults, may not be wrong. In a cohort involving 30 children (13 boys and 17 girls) with apparently sporadic pituitary adenomas of different types (Table 1), we found an AIP mutation in 7 children (23.3%)...

Methodist Hospital will soon have new brain and pituitary tumor treatment center
Brain and pituitary tumor patients will soon have access to a state-of-the-art facility at The Methodist Hospital, a result of a $10 million dollar commitment from a Houston oil executive.
Pituitary gland: New pathways in the pathogenesis of pituitary adenomas
Acromegaly is caused by a growth-hormone-secreting pituitary adenoma. Mutations in the AIP gene predispose patients to young-onset pituitary adenomas that are resistant to somatostatin analogue therap...
Changes in pituitary function with ageing and implications for patient care
Multiple subtle changes in hypothalamic–pituitary function occur with ageing. This Review discusses the mechanisms mediating these changes in pituitary function during ageing and the implications fo...

Tumor-to-tumor metastasis from pituitary carcinoma to radiation-induced meningioma.
Radiation-induced meningioma and pituitary carcinoma are both uncommon. Tumor-to-tumor metastasis (TTM) from pituitary carcinoma to meningioma, to our knowledge, has not been previously reported. A 67...
Expression of pituitary tumor transforming gene (PTTG) in human pituitary macroadenomas.
The purpose of this study was to elucidate the relationship between pituitary tumor transforming gene (PTTG) and invasiveness in pituitary macroadenomas and to determine the association between PTTG a...
Pathogenesis of pituitary tumors.
Pituitary adenomas may hypersecrete hormones (including prolactin, growth hormone and adrenocorticotropic hormone, and rarely follicle-stimulating hormone, luteinizing hormone or TSH) or may be nonfun...
Acromegaly due to an ectopic pituitary adenoma in the clivus: case report and review of literature.
Pituitary adenomas rarely originate outside the sella turcica. Ectopic locations include the suprasellar region, sphenoid sinus, cavernous sinus and clivus. We describe a 50-year-old female who presen...
Pituitary apoplexy (PA) typically results from infarction or hemorrhage in a pituitary adenoma, while PA in nonadenomatous pituitary gland is uncommon. Prothrombotic states have never been recognized...
