title: Hyperprolactinemia in multiple endocrine adenomatosis, type 1.
abstract: Three cases are described in which hyperprolactinemia occurred as a feature of multiple endocrine adenomatosis, type 1 (MEA-1); enlargement of the sella turcica varied from gross to absent, and serum prolactin (PRL) levels ranged from 21 to 1,000 ng/ml in these cases. Since PRL-secreting pituitary tumors may occur with variable presentation in MEA-1, periodic measurements of serum PRL levels should be carried out to detect this abnormality.
