Prolactinoma of pituitary with associated amyloid-like substances. Case report.
A prolactin-secreting pituitary adenoma containing amyloid substance was studied by light and electron microscopy. The tumor was found in a 32-year-old woman who presented with a short history of amenorrhea and galactorrhea. Pituitary adenoma containing amyloid substance is a very rare entity, and the implications of this association are discussed. Previous reports, suggesting that mesenchymal cells or hormone-secreting tumor cells in pituitary adenomas produce amyloid substances, are reviewed.
