Lymphocytic hypophysitis.

LYMPHOCYTIC HYPOPHYSITIS is an unusual disorder that nearly exclusively affects women; fewer than 50 cases have been reported in the literature. The present case also is unusual because a normal computed tomographic (CT) scan had been obtained of the sella shortly before the development of a large pituitary mass due to lymphocytic hypophysitis. Lymphocytes were characterized using immunoperoxidase stains. A probably unrelated malabsorption syndrome later complicated her hormone replacement therapy.
