Multiple cutaneous sensitization to nonsteroidal anti-inflammatory drugs.
The use of topical nonsteroidal anti-inflammatory drugs is widespread (particularly in countries bordering the Mediterranean). Compared to their wide use, the incidence of published adverse cutaneous effects appears minimal, although they are increasing. Most of them are a form of allergic contact dermatitis (ACD). Multiple sensitization and/or cross-reactions are rarely reported. Interestingly, our patient presented ACD with diclofenac and etofenamate (both from different chemical groups) and, furthermore, patch tests were positive with bencydamine and indomethacin (both indolacetic acid derivatives), piroxicam and fepradinol. We think that our results could not be explained due to cross-reactivity, and that multiple sensitization was more likely.
