Enlarged pituitary gland are abnormal growths found in the pituitary gland makes hormones that affect the growth and function of other glands in the body. Enlarged pituitary gland is a pea-sized, reddish-gray organ in the center of the brain, just above and behind the nose.
Pituitary carcinoma occurs in both sexes, usually by the third or fourth decade of life. These tumors are very common with 25% of people who have small pituitary tumors at autopsy but most are free of symptoms and largely undiagnosed pituitary adenomas throughout life.
Type named after the type of pituitary hormone prolactin, which makes and including producing adenoma, somatotrophin secreting adenoma, corticotrophin-secreting adenomas, gonadotropin-secreting adenomas, adenomas secrete thyrotrophin, null cell adenomas, and adenomas of mixed cell types. Another type of pituitary cancer appears as a very large hands, feet and face (acromegaly). The third type of pituitary tumor tissue covering; Chromophobe adenoma (90%), Basophil Eosinophil adenoma and adenoma.
Although the exact cause is unknown, the tendency for pituitary tumors can be inherited through an autosomal dominant trait. Chromophobe adenoma may be associated with the production of corticotrophin, melanocyte stimulating hormone, growth hormone and prolactin. Basophil adenoma with corticotrophin excess production and consequently with Cushing's syndrome. Eosinophil adenoma with excessive production of growth hormone.
Enlarged pituitary gland grow they replace normal glandular tissue and enlarge the network that houses the pituitary gland (sella turcica). The resulting pressure on the adjacent intracranial structures produce the following symptoms characteristic: frontal headache, visual disturbances, changes in personality or dementia, seizures, head tilt and dizziness, strabismus, nystagmus, nausea and vomiting, or one of the problems caused by the production of too many hormones such as infertility or loss of menstrual periods in women, abnormal growth, high blood pressure, heat or cold intolerance, and changes in the skin and other body.
