Dermatitis herpetiformis is an autoimmune skin disorder frequently ass
ociated with gastrointestinal diseases. We report a 53-year-old male w
ith a four-year history of refractory dermatitis herpetiformis associa
ted with hypopituitarism. Endocrine testing, ophthalmological examinat
ion and magnetic resonance imaging revealed hypopituitarism due to a n
on-functioning pituitary macroadenoma. Following transsphenoidal remov
al of the pituitary tumor and appropriate hormone replacement, complet
e remission of the skin disorder was obtained. We discuss the permissi
ve role of panhypopituitarism in the course of dermatitis herpetiformi
s.
