Active sensitization and occupational allergic contact dermatitis caused by para-tertiary-butylcatechol.

Para-tertiary-butylcatechol (PTBC) is a rare allergen which is used in the rubber, paint and petroleum industries. We present 9 patients who were sensitized to PTBC and examined at the Finnish Institute of Occupational Health (FIOH) between 1974 and 1995. 3 of the patients had been exposed to PTBC in their work. 2 of them also had allergic reactions to para-tertiary-butylphenol (PTBP)-formaldehyde resin and to PTBP. 5 of the patients became sensitized to PTBC from patch testing. PTBC was found to be one of the most common causes of active sensitization in our clinic. Accordingly, at the FIOH, the patch test concentration of PTBC was lowered to 0.25% and this lower concentration is recommended for general use.

Airborne occupational allergic contact dermatitis from champignon mushroom.

BACKGROUND: Allergic contact dermatitis from mushrooms has only seldom been reported. OBJECTIVES: We report on a mushroom picker who developed skin symptoms from occupational exposure to the mushroom champignon. METHODS: Conventional patch testing and prick testings were performed. RESULTS: 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. CONCLUSION: 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.
