71 surgically removed pituitary adenomas with amyloid deposits were studied by light microscopical and immunohistological means. In none of the adenomas was there a predominance of amyloid deposits. There were no correlations between the extent or pattern of the deposits with either age, immunohistological hormone content or localization.

Tumor galanin content was measured in extracts from human pituitary adenomas using a specific RIA method for monitoring human galanin. Twenty-two out of twenty-four tumors contained galanin with notably high levels in corticotroph adenomas, varying levels in clinically inactive tumors, and low levels in GH secreting adenomas.

Because adenomas of the pituitary are present in 10% to 20% of healthy individuals, the finding of incidental sellar lesions on computed tomography scanning or magnetic resonance imaging has become relatively common. Hyperfunctioning of such lesions can be excluded clinically and by hormonal screening.

Angiogenesis in pituitary adenomas
Microscopy Research and Technique, 2003AbstractAngiogenesis, which is the formation of new blood vessels from preexisting capillaries, plays an important role in tumor growth and metastasis. In this review, the focus is on angiogenesis in pituitary adenomas. Angiogenesis of pituitary adenomas has been assessed by studying tumor microvessel density using specific immunohistochemical markers ...

Pituitary adenomas are frequently silent. Among silent adenomas, some are clinically silent but can be detected on the basis of the excessive secretion of hormonal products, whereas others are totally silent and cannot be detected by hormonal measurements. Treatment of a silent pituitary adenoma depends on its size and extent.

MEN1 gene mutations predispose carriers to pituitary tumors. Molecular pathways involved in the development of these tumors seem different to what is known in sporadic tumors. Clinical studies showed that all types of adenomas can be found with a predominance of prolactinoma and macroadenoma compared to a control population. These MEN1 tumors seem more
