Erythema Ab Igne
(Diseases)
On this page, you will find everything you need to know about Erythema Ab Igne.
What is Erythema Ab Igne?
- Erythema ab igne, also known by several names such as toasted skin syndrome, fire stains, thermal rash, or reticular erythema, is a skin reaction that occurs as a result of continuous and repeated exposure to heat sources. The condition begins with the appearance of pink patches on the skin, which gradually develop into a net-like (reticular) pattern over time. It commonly affects individuals frequently exposed to heat, such as metal workers, bakers, cooks, and others working in high-temperature environments.
- What are the Symptoms of Erythema Ab Igne?
- Pink patches that develop into a net-like or reticulated rash, usually brownish or reddish in color.
- Skin discoloration that darkens over time, possibly turning brown or purplish.
Itching or a burning sensation.
In some cases, the appearance of blisters.
What are the Causes of Erythema Ab Igne?
Chronic exposure to mild to moderate heat, such as sitting for long periods near heaters, or prolonged use of heating pads and warming devices. While such exposure may not cause burns, it can, over time, lead to erythema ab igne. This persistent heat exposure negatively affects the skin and blood vessels, causing dilation and inflammation, which leads to redness. Similarly, placing a laptop directly on the legs or abdomen for extended periods can cause the same effects, resulting in skin damage and discoloration over time.
- How is Erythema Ab Igne Diagnosed?
- Diagnosis is based on medical history and clinical examination of the skin. In rare cases, additional procedures may be required, such as:
Taking a detailed history of heat exposure.
Skin biopsy to rule out other similar conditions (though rarely needed).
- What Are the Treatment Methods for Erythema Ab Igne?
- Treatment may involve several measures, depending on the severity of the case:
- Discontinuing prolonged exposure to the heat source.
Proper skin care and use of moisturizers to relieve dryness and itching.
- Cosmetic treatments, such as laser therapy and depigmenting creams.
- What Are the Prevention Methods for Erythema Ab Igne?
- Avoid prolonged exposure to heat sources, such as stoves, heaters, and laptops.
- Do not place hot devices directly on the skin for long periods.
- Use a barrier, such as a pillow or laptop stand, to minimize direct heat exposure.
- Prefer heating devices equipped with advanced technology, such as automatic shut-off when a certain temperature is reached, to prevent excessive exposure.
Change your body position regularly to avoid long-term exposure to one skin area when working near a heat source.
Regularly examine the skin, especially areas frequently exposed to heat.
What Are the Complications of Erythema Ab Igne?
- If exposure to heat continues without treatment, the rash may progress to permanent skin changes, and in rare cases, it may lead to skin cancer.
- When should you see a doctor?
If you notice persistent changes in skin color or the appearance of sores or ulcers in the affected area.
If symptoms persist or worsen despite avoiding heat exposure.
