Current Opinion in Endocrinology, Diabetes & Obesity, 2012
This review focuses on recently published literature on pituitary tumors in children with special focus on craniopharyngioma and prolactinoma. Although most pituitary masses are benign neoplasms, they are associated with high morbidity and mortality related to their proximity to vital neurologic structures including the optic chiasm, hypophysis and ...

Radiotherapy of Pituitary Tumors
Endocrinology and Metabolism Clinics of North America, 1987The treatment of pituitary adenomas with conventional radiotherapy is safe and effective. Radiation controls the mass effects of large tumors in 80 to 90 per cent of patients and is especially valuable in preventing recurrence after partial resection. In acromegaly, about 80 per cent of patients are controlled; with Cushing's disease, the ultimate cure

Scintigraphy of Pituitary Tumors [PDF]
, 2000 Several neoplastic and non-neoplastic lesions may arise within the sellar and parasellar regions (Table 1). Among these, pituitary adenomas are the most common. Almost all pituitary tumors are benign, although they may display signs of local invasion or show histological evidence of malignancy.

Pituitary enlargement mimicking pituitary tumor
Journal of Neurosurgery, 1985✓ Primary hypothyroidism can result in reactive enlargement of the pituitary gland which is indistinguishable from primary pituitary lesions on computerized tomography (CT) scans. The presenting symptoms may be due to pituitary gland enlargement, as in two of the three cases reported here.

Pituitary Tumors and Hyperprolactinemia
Archives of Internal Medicine, 1976Hyperprolactinemia was demonstrated in eight of nine patients with clinical evidence of pituitary tumors without acromegaly or Cushing syndrome. Hourly sampling for 24 hours disclosed elevation of serum prolactin concentrations, whereas, measurable serum growth hormone levels were found rarely.

Endocrinology and Metabolism Clinics of North America, 1987
This article reviewed the classification, morphologic features, and pathogenesis of human hypophyseal adenomas and differences between hyperplasia and adenoma. Histologic, immunohistochemical, and electron microscopic investigation obtained a deeper insight into several aspects of pituitary cytopathology.

Hormone Research in Paediatrics, 2007
<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 tumors and pregnancy
American Journal of Obstetrics and Gynecology, 1978This paper contains a review of the natural history of pituitary tumors in nonpregnant and pregnant patients. Data were drawn from previously published reports and from responses to a questionnaire and were analyzed by life-table techniques. Follow-up of 62 nonpregnant patients with untreated pituitary tumors with and without visual field changes ...

Pathogenesis of Pituitary Tumors
Endocrinology and Metabolism Clinics of North America, 1987Evidence for and against the hypothesis that GH-, PRL-, and ACTH-secreting tumors arise as the result of hypothalamic dysregulation has been presented. For each of these types of tumor it appears that similar proportions--perhaps 80 to 90 per cent arise de novo within the pituitary. Although it is quite possible, it is not yet proven that the remaining

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.
