Functional hyperprolactinemia and hypophyseal microadenoma in systemic sclerosis.

Objective: Hyperprolactinemia (HPRL) has been identified in more than half of patients with systemic sclerosis (SSc). However, the association with pituitary adenoma and the status of hypothalamic dopaminergic tone using metoclopramide (MTC) test has not been studied. We investigated the prevalence of prolactin (PRL)-secreting pituitary adenoma and evaluated production of PRL by dynamic testing with MTC in SSc.
