Abstract
-
Erythema ab igne (EAI) refers to the development of persistent areas of reticular erythema, often with pigmentation, at the sites of repeated exposures to heat, usually from open hearths. Although the incidence of EAI has declined due to the advent of central heating, various other causes have recently been reported, including hot water bottles, heating pads used to treat ailments, heated blankets, car heaters, and laptop computers. We present a case of 23-year-old Korean woman with an asymptomatic patch on her trunk, which had occurred a month before due to use of weight loss heating pad for weight reduction.
