Erythema Ab Igne: Erythema ab igne (eai) is a skin reaction caused by chronic exposure to infrared radiation in the form of heat. It was once a common condition seen in the elderly who stood or sat closely to open fires or electric space heaters. Although the introduction of central heating has reduced eai of this type, it is still found in individuals exposed to heat from other sources.
