Abstract:
We report a case of piroxicam-induced photosensitive dermatitis in a 54-year-old female. She had taken oral piroxicam and was exposed to the sunlight on her way home for a few minutes. Several hours after the sun-exposure she developed well-defined, confluent, erythematous plaques and numerous vesicobullae with pruritus and prickling sensation on the sun-exposed areas. A phototest was done on her first visit. The minimal erythemogenic dose (2 J/cm²) of ultraviolet (UV) A was markedly decreased whereas that of UVB was within a normal limit. Visible light irradiation for 30 minutes did not cause skin lesions. Six months after the initial skin lesions, a photopatch test with 1% and 10% piroxicam solution followed by UVA (10 J/cm²) irradiation showed positive responses on both concentrations.
