Sir, Erythema ab igne (EAI) was first described in the UK by German dermatologist Abraham Buschke in the early 1900s as a result of proximity to stoves burning with peat.[1] It is caused by repeated and prolonged exposure to infrared radiation insufficient to produce burns.[2,3] Heat radiation may be due to repeated body – warming techniques like the use of Kangri — an indigenous fire pot used to generate warmth during winter months- by the people of northern India,[4,5] frequent hot bathing, hot water bottles, heating pads, and cooking.[2,3] The initial manifestation of EAI is the presence of red macules at the site of exposure. These macules are most often found on the back or the lower leg parts of women. With continued episodes of heat exposure, the skin reaction evolves into a hyperpigmented reticulated macular eruption with dusky erythema, telangiectasia, and epidermal atrophy. Symptoms of burning or itching may be described by patients,[3,6] although bullae are rarely seen.[7,8] Arriving at the diagnosis of bullous EAI may be easy if it be supported by the patient's history. However, if this history is vague or if the patient denies heat injury, confirming such a diagnosis can be difficult. A combination of history, physical findings, and histology should confirm the diagnosis.[
