Overview: Erythema ab igne (EAI) is caused by chronic or prolonged heat exposure without burning. EAI commonly occurs over the shins due to prolonged exposure to fireplaces and heaters, the lower back due to electric heating pads, and the thighs from prolonged laptop exposure and heated car seats.

Erythema ab igne is a skin disorder caused by overexposure to infrared radiation. Characteristic features include erythematous patches with hyperpigmentation and telangiectasia. A typical history would be an elderly woman who always sits next to an open fire.

Perform a general examination. Look for evidence of weight loss, malnutrition, jaundice and/or stigmata of liver disease. Erythema ab igne from frequent application of a hot water bottle is often seen. Examination may be normal, but examine for a palpable epi-gastric mass representing an inflamed or fibrosed pancreas or a pseudocyst. Rupture of a pseudocyst may produce ascites. Splenomegaly usually indicates splenic vein thrombosis.

Erythema ab igne (EAI) is a dermatosis characterized by local or regional patches of reticulated erythema and hyperpigmentation caused by chronic exposure to moderate intensity heat. It is believed that heat induces injury to the epidermis and superficial vascular plexus. Historically, EAI was associated with women working with coal stoves or open fires, specifically their anterior legs as this region was most directly exposed to the fire. The introduction of central heating—and the subsequent abandonment of hearth-type heating—has led to a decreased incidence of EAI. In modern societies, EAI is increasingly related to localized heat exposure, such as prolonged use of direct or radiant heating devices (eg, heating pads, warm bottles, and space heaters) in the treatment of painful chronic conditions1,2 or the use of laptop computers placed on the anterior thighs.3

Erythema ab igne are reported mainly with the use of laptops and the habit of supporting them on the legs in contact with the skin during prolonged use, as reported in a clinical case by Giraldi et al. (32), in which the injuries were distributed in the locations with higher incidence of IR radiation. Heat can play an important role as a physical stimulus for angiogenesis, regulation of cytokines, production of ROS and damage to the DNA of skin cells. In addition, due to heat, there is an increase in the expression of MMP-1, MMP-3 and MMP-12 in the skin, which leads to the degradation of extracellular matrix proteins, such as collagen and elastin and can destroy existing fiber networks, causing photoaging (29).
