A Case of Therapy-Resistant Folliculitis due to Adrenal Insufficiency?

A report on a 40-year-old patient with recalcitrant, suppurative folliculitis is presented.

A few weeks after the patient was subjected to substitution therapy with hydrocortisone, his folliculitis resolved. We discuss the role of plasma cortisol level in the pathogenesis of folliculitis.
