ResumoAllergic contact dermatitis from mushrooms has only seldom been reported.We report on a mushroom picker who developed skin symptoms from occupational exposure to the mushroom champignon.Conventional patch testing and prick testings were performed.Erythema and vesicular edemic dermatitis appeared around the eyes, on the cheeks, around the nose, and around the lips of a 31-year-old woman who had been involved in the commercial production of champignons for 5 years. Prick testing to champignon was negative, but patch testing with raw champignon provoked a 2+ allergic reaction and was negative in the controls.Our patient had been occupationally sensitized from exposure to champignon. The allergen is not known but may be a low-molecularweight chemical or a protein present in the champignon.
