Abstract

Methylisothiazolinone (MI) is a preservative found in cosmetic, personal hygiene, and industrial products. It has been characterized as a moderate to strong sensitizer and is an emerging allergen in the pediatric population. We discuss a case of perianal dermatitis in a child caused by contact allergy to MI-containing wet wipes.
