Neurosurgery, 1991
Abstract This retrospective review of pediatric patients with pituitary tumors causing onset of symptoms by 17 years of age was done to define their pathological distribution, clinical presentation, treatment, and prognosis. Eighteen patients were evaluated and treated from 1979 to 1989.

Aggressive Pituitary Tumors or Localized Pituitary Carcinomas: Defining Pituitary Tumors
Expert Review of Endocrinology & Metabolism, 2016Pituitary tumors are common and exhibit a wide spectrum of hormonal, proliferative and invasive behaviors. Traditional classifications consider them malignant only when they exhibit metastasis. Patients who suffer morbidity and mortality from aggressive tumors classified as "adenomas" are denied support provided to patients with "cancers" and in many ...

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 hyperplasia mimicking pituitary tumor
Surgical Neurology, 1994Reactive enlargement of the pituitary gland in primary end organ failure may be indistinguishable from primary pituitary lesions in clinical presentation and on magnetic resonance imaging. The diagnosis of pituitary hyperplasia secondary to end organ failure must be based on endocrinologic investigations.

Angiogenesis and Pituitary Tumors
Seminars in Ophthalmology, 2009Pituitary adenomas often first manifest through visual symptoms. They are typically slow-growing and histologically benign tumors, but can become clinically destructive, invade adjacent structures, and recur after treatment. Unlike many other tumors that become aggressive and appear to depend upon angiogenesis in the process, pituitary adenomas tend to

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.

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 ...

PATHOGENESIS OF PITUITARY TUMORS
Endocrinology and Metabolism Clinics of North America, 1999Pituitary adenomas may hypersecrete hormones (including prolactin, growth hormone and adrenocorticotropic hormone, and rarely follicle-stimulating hormone, luteinizing hormone or TSH) or may be nonfunctional. Despite their high prevalence in the general population, these tumors are invariably benign and exhibit features of differentiated pituitary cell

Molecular and Cellular Endocrinology, 2017
Since the presence of microRNAs was first observed in normal pituitary, the majority of scientific publications addressing their role and the function of microRNAs in the pituitary have been based on pituitary tumor studies. In this review, we briefly describe the involvement of microRNAs in the synthesis of pituitary hormones and we present a ...

Endocrinology and Metabolism Clinics of North America, 1988
In the last two decades, significant strides have been made in the diagnosis and management of pituitary tumors. The identification, isolation, and characterization of the anterior pituitary hormones, the developments of sensitive and specific radioimmunoassays, and the significant advances in neuroradiologic, neurosurgical, and pathologic techniques ...
