A 66-year-old male was observed with 1-year history of recurrent, pruriginous, and erythematous plaques in his face and neck, not related to his work (printing industry), with transient improvement on topical treatment. Patch tests were performed with the Portuguese Contact Dermatitis Study Group baseline series, with an extended cosmetic and photo-allergen series, including the UV filters provided for the European Multi-Centre Photopatch Test Study. On D2/D4 there was only a positive reaction (++) for Tinosorb M® (10% pet.), with no further aggravation after 5 J/cm2 UV irradiation. This reaction was considered relevant, as the patient was regularly using a facial sunscreen (Avène®) containing Tinosorb M® and lesions cleared on stopping its application. Further patch testing with decyl glucoside (5% pet.), several commercial sunscreens, and other cosmetics containing different glucosides (myristyl-, coco-, lauryl-, arachidyl-, cetearyland xylityl glucosides) revealed positive reactions (++) to decyl glucoside, Tinosorb M® and sunscreens containing Tinosorb M®, and also all cosmetics containing myristyl-, coco-, and lauryl glucosides.
