P46 Allergic contact dermatitis to a retarding cream in a condom

Abstract

We describe a case of a 42‐year‐old non atopic man with a history of ano‐perianal eczema in consequence of the use of anti‐haemorroidal ointments and allergic contact dermatitis to Myroxylon pereirae, benzocaine, paraben mix and paraphenylenediamine. He was referred to our Unit for a strong eczematous reaction in the genital area with a marked oedema of the balanoprepuzial region that had appeared some hours after the use of a condom (Settebello‐Hatù® Durex) made of natural latex and containing a retarding cream composed with benzocaine 5%, polyethylene glycol plus glycerin 94,7% and paraben 0,3% as preservative. The suspension of the use of the condom and treatment with a corticosteroid cream healed the eruption in few days. Patch testing with the SIDAPA (Società Italiana di Dermatologia Allergologica, Professionale e Ambientale) standard series, an additional rubber series, a piece of the rubber’s condom washed clean of cream and the condom’s cream gave positive reactions to Myroxylon pereirae, benzocaine, paraben mix, paraphenylenediamine and condom’s cream. Further patch test with the other ingredients of condom’s cream was negative as well as latex prick test. We discuss about the ethiologic agents and the most useful diagnostic test in allergic contact dermatitis condom‐related and the preventive measures that should be adopted.
