[Photocontacs dermatitis due to dexketoprofen. Report of 2 cases].
Dexketoprofen is the active isomer of ketoprofen and likewise belongs to the group of non-steroidal anti-inflammatory drugs (NSAIDs) derived from propionic acid. We have recently studied, using patch and photopatch tests, two women with a characteristic clinical picture of contact photodermatitis who had used topical dexketoprofen (Enangel) in the days before onset of the rash. In both cases we used the standard series of GEIDC, a series for NSAIDs, the product itself (Enalgel) and its excipients. On examination of the photopatches of both patients at 96 hours we found positive reactions to dexketoprofen and Enalgel. Furthermore, in one of the women we observed simultaneous photosensitivity to other NSAIDs and to several excipients of Enangel. Reviewing the literature we have found only three references on contact photodermatitis due to dexketoprofen. We describe two new cases, with multiple photosensitivities in one of them. We consider that such patients should be patch tested with dexketoprofen at 0.1-1 % petrolatum, concentrations that are notably inferior to those used in previous publications.
