Learn about toasted skin syndrome, a condition caused by prolonged exposure to heat sources like laptops, space heaters, and heating pads. This article explains the causes, symptoms, and diagnosis of this increasingly common skin issue.
Prolonged exposure to heat sources like laptops, space heaters , or heating pads can lead to an unexpected skin condition called toasted skin syndrome . This syndrome, also known as erythema ab igne, occurs when the heat damages the surface of the skin and its superficial blood vessels.
The repeated exposure to heat, although not hot enough to cause a burn, causes inflammation and the deposition of pigments like hemosiderin (a brown iron-containing molecule) and melanin (responsible for skin color) in the skin. This results in a distinctive net-like or fishnet pattern on the affected area. Dermatologists emphasize that toasted skin syndrome develops gradually over time due to chronic heat exposure. A single instance of using a heating pad for an injury is unlikely to cause the syndrome. It's the frequent and prolonged use of these heat sources, especially on bare skin, that poses the risk. Laptops and heating pads are among the most common culprits, followed by hot water bottles, space heaters, and electric fireplaces. Certain occupations, such as cooking, baking, or glass blowing, can also increase the likelihood of developing toasted skin syndrome due to prolonged exposure to heat sources.The diagnosis of toasted skin syndrome is typically straightforward as it presents a characteristic appearance. Dermatologists can identify the condition by examining the skin for the distinctive red or brown fishnet pattern. This pattern corresponds to the distribution of the superficial blood vessels that have been damaged by the heat. Importantly, toasted skin syndrome is usually asymptomatic, meaning patients don't experience any pain or discomfort. The visible skin pattern is the primary indicator of the condition
