BackgroundContact dermatitis from topical antiseptic use has been reported mostly in adults, but rare cases of chlorhexidine contact dermatitis have also been described in young children.ObjectiveTo evaluate contact allergic dermatitis to antiseptics in young children.MethodsThe children mostly referred for a misdiagnose (cellulitis) were patch tested with a selection of the European baseline series, an antiseptics series and the personal topical products used.ResultsFourteen children (8 boys, 6 girls) received a diagnosis of contact dermatitis to antiseptics between May 2010 and December 2017. The mean age at diagnosis was 38 months (8 months to 8 years); three children only had a personal history of atopy. Chlorhexidine gluconate was positive in seven cases, and benzalkonium chloride in eight cases, and in four cases, both allergens were positive.ConclusionThese small case series confirm that both chlorhexidine and benzalkonium chloride are implicated in contact dermatitis from antiseptic use in the paediatric population. We emphasize the initial misdiagnose of these patients, the very young age of the children and the allergenic potential of common antiseptics in non-atopic children. We hypothesize that the systematic use of antiseptics for umbilical cord care could be responsible for the sensitization in newborns.© 2018 European Academy of Dermatology and Venereology.
