title: It is not a fixed drug eruption, it is a fixed "sunlight" eruption.
abstract: Hyperpigmented fixed eruption is a phenomenon usually related with drug antigens, and known as fixed drug eruption. A woman had a skin condition with clinical and histopathologic indications of fixed drug eruption. The disease first appeared when she went to a swimming pool and left with hyperpigmented macules. Previously affected skin reactivated on three other occasions when she again visited swimming pools. Sunlight involvement (UVA-UVB) was demonstrated through phototests. Sunlight should be considered as a cause of fixed drug-like eruption and a possible cause of some cases of FDE without any apparent etiological factor.
