skin condition from prolonged heat exposure, also called toasted skin syndrome
Erythema ab igne, also known as "toasted skin syndrome," is a skin condition caused by prolonged exposure to infrared radiation or heat. It manifests as a reticulated, or net-like, pattern of erythema (redness) and hyperpigmentation on the skin. This condition often occurs in individuals who frequently use heating pads, hot water bottles, or sit too close to space heaters. If the exposure continues, it can lead to permanent skin changes and, in rare cases, increase the risk of skin cancer.
