Erythema ab igne
Erythema Ab Igne (EAI)[edit | edit source]
Erythema Ab Igne (EAI), commonly referred to as hot water bottle rash, is a skin condition resulting from long-term exposure to heat or infrared radiation. This prolonged exposure can cause specific changes in the skin, typically in areas where the skin is heated repeatedly.
Causes[edit | edit source]
- EAI is caused by chronic exposure to moderate heat that is insufficient to cause a burn but strong enough to induce skin changes.
- Common sources include hot water bottles, heating pads, and laptops placed on laps.
Symptoms and Characteristics[edit | edit source]
- The condition is characterized by reticulated erythema, hyperpigmentation, scaling, and telangiectasias in the affected area.
- Mild itchiness and a burning sensation may occur.
- In many cases, EAI is asymptomatic and may go unnoticed until visible skin changes appear.
Diagnosis[edit | edit source]
- Diagnosis of EAI is primarily clinical, based on the characteristic appearance of the skin and the patient's history of heat exposure.
- Dermatological examination is used to rule out other skin conditions.
Treatment and Management[edit | edit source]
- The most effective treatment is the removal of the heat source to prevent further skin damage.
- Topical treatments may help in reducing symptoms and improving skin appearance.
- In some cases, laser therapy might be considered for cosmetic reasons.
Prevention[edit | edit source]
- Prevention involves avoiding prolonged direct exposure to heat sources.
- Using barriers or protective layers between the skin and heat sources can reduce the risk.
Potential Complications[edit | edit source]
- Chronic EAI can lead to permanent skin changes.
- In rare cases, there's a risk of skin cancer developing in the affected areas.
