Erythema ab igne 是由于反复暴露于热或红外线辐射而引起的皮疹。它经常发生在工作或使用加热垫时。主要处理方法是除去热源。皮疹可能会随着时间的推移而消退，但可能会留下永久性色素沉着或疤痕。维甲酸或氢醌等治疗方法可以帮助缓解持续性色素沉着过度。
Erythema ab igne is a rash characterized by a reticulated pattern of erythema and hyperpigmentation. It is caused by repeated exposure to direct heat or infrared radiation, often from occupational exposure or the use of heating pads. The primary treatment of this disease entity is the removal of the offending heat source. The resulting abnormal pigmentation of affected areas may resolve over months to years; however, permanent hyperpigmentation or scarring may persist. Treatments for hyperpigmentation, such as topical tretinoin or hydroquinone, can be useful in treating persistent hyperpigmentation.

不同类型的热源可能会导致这种情况，例如：
- 反复使用热水袋、电热毯或热垫来治疗慢性疼痛。
- 反复暴露于加热的汽车座椅、小型取暖器或壁炉中。反复或长时间接触加热器是老年人的常见原因。
- 银匠和珠宝商（脸部受热）、面包师和厨师（手臂、脸部）的职业危害
- 将笔记本电脑放在大腿上（笔记本电脑引起的红斑）。
