title: [Erythema multiforme-like reaction to para-phenylenediamine].
abstract: A case of a 15 year-old girl who developed an erythema multiforme-like reaction to para-phenylenediamine (PPD) after Henna tattoos is described. The patient was treated successfully with oral prednisolone and highly potent topical corticosteroids. The patient developed a long-lasting post-inflammatory hyperpigmentation. Potential hyperreactive response was prevented by applying the PPD patch for only 30 minutes, but still there was a significantly positive reaction. This case highlights the need to ban the use of para-phenylenediamine and its derivates in dyes.
