title: Null cell adenomas and oncocytomas of the pituitary gland.
abstract: This review highlights the most interesting features of null cell adenomas and oncocytomas of the pituitary gland. Recently, application of sensitive methods have documented a very low amount of active hormone production in these clinically nonfunctioning tumours. However, further studies are needed to clarify the histogenesis of null cell adenomas and oncocytomas.
