Few human pituitary tumor cell lines have been established. This scarcity may be related to the fact that hormone production rapidly declines within weeks to months after initiation of the culture. In addition, the number of proliferating cells in pituitary adenomas is very low.

Pituitary malignancies are rare. The definition of pituitary malignancy is still subject to debate. Three types of malignancy with the description of clinical course and complete autopsy were presented; i) true carcinosarcoma, ii) ectopic sphenoid invasive tumor, and iii) post-irradiation sarcoma.

<i>Background:</i> Pituitary tumors are common and usually grow insidiously over many years. Rarely fatal, treatment still requires multiple cytoreductive surgeries and/or radiation therapy with its attendant side effects. As a disease process of regulatory pathways, pituitary tumors offer numerous potential therapeutic targets, and many ...

Pituitary adenomas are benign intracranial neoplasms that present a major clinical concern due to hormone overproduction and/or tumor mass effects. The majority of pituitary adenomas occur sporadically; however, familial cases are increasingly being recognized, such as multiple endocrine neoplasia type 1 (MEN1), Carney complex (CNC), and familial ...

Familial Pituitary Tumor Syndromes
Endocrine Practice, 2011To summarize current knowledge on the clinical and genetic characteristics of familial pituitary tumor syndromes.This review is based on a comprehensive search through the English-language literature with use of the following terms: "familial," "pituitary," "adenomas," and "tumors."Familial pituitary tumors are rare and constitute approximately 5% of ...

Pituitary adenomas represent a common intracranial pathology, usually resulting in the systemic secretion of hormones and compression of local endocrine and optic structures, causing a wide variety of clinical sequelae. While they are typically treated with upfront endocrine and/or surgical decompressive therapy, in patients with residual, recurrent ...

Endocrinology and Metabolism Clinics of North America, 1987
Nonfunctioning pituitary adenomas represent approximately 25 per cent of all clinically apparent pituitary tumors. The tumors are usually macroadenomas and present with symptoms caused by mass effect or hypopituitarism. In addition to structural studies and assessment of pituitary hormone function, all patients with clinically nonfunctioning tumors ...

Nonfunctioning pituitary tumors
2014Clinically nonfunctioning adenomas range from being completely asymptomatic, and therefore detected either at autopsy or as incidental findings on head MRI or CT scans performed for other reasons, to causing significant hypothalamic/pituitary dysfunction and visual field compromise due to their large size.

Pituitary tumors and pregnancy
Growth Hormone & IGF Research, 2003Tumors vary in how they affect pregnancy depending upon the hormone secreted. Some hormone oversecretion syndromes must be controlled to allow pregnancy to proceed without undue maternal and fetal morbidity (Cushing's disease and hyperthyroidism) whereas treatment during pregnancy for other tumors is not necessary.
