title: Solar urticaria confined to areas of bruising.
abstract: Solar urticaria is a rare immunoglobulin E-mediated photodermatosis characterized by the development of a pathognomic wheal and flare within minutes of photoexposure. A 26-year-old man presented with a history of sun-induced urticaria only in areas of pre-existing bruising, which we were able to replicate with monochromator testing. We were also able to demonstrate, by autologous in vitro studies, that a serum factor was responsible.
