Vesicular Hand Dermatitis in a Child: Allergy to Methylisothiazolinone

Abstract A 7‐year‐old girl presented with a history of vesicular hand dermatitis that only partially improved with the use of steroids. Patch testing revealed a 1+ reaction to 0.2% aqueous methylisothiazolinone (MI) and 0.01% aqueous methylchloroisothazolinone/methylisothiazolinone (MCI/MI). Dyshidrosiform hand dermatitis is rare in children younger than 10 years of age, and this pattern has not been reported with MCI/MI allergy.
