Abstract

Methylisothiazolinone (MI) is an emerging and increasing cause of allergic contact dermatitis (ACD) in children. We present the case of a 7-year-old girl with an unusual dermatitis suspicious for contact allergy. Patch testing confirmed allergy to MI, found only in the patient's laundry detergent. This case highlights the importance of checking household product ingredients and the role of MI as an increasing cause of ACD in children.
