title: Prolactinoma coexistent with granulomatous hypophysitis.
abstract: A 54-year-old man with a long-lasting left-sided headache and biochemical evidence of hyperprolactinemia was found to have a large chromophobe pituitary adenoma, which concurred with a granulomatous hypophysitis. The mechanism of the inflammatory reaction is discussed and the immunohistochemical and ultrastructural findings of this hitherto undescribed combination of lesions are presented.
