Erythema ab igne [dermatitis ab igne]

Erythema ab igne, also known as dermatitis ab igne, is a skin condition that occurs due to prolonged exposure to heat or infrared radiation. The term "erythema ab igne" literally means "redness from fire" in Latin, reflecting the characteristic appearance of the condition.

People who frequently use heating pads, hot water bottles, or sit close to fireplaces or space heaters are at risk of developing erythema ab igne. The condition typically manifests as a localized area of redness on the skin, which may be accompanied by itching or a burning sensation.

1. Cause: Erythema ab igne is caused by prolonged exposure to heat. This can be from external sources such as hot objects or radiant heat, or from internal sources such as chronic inflammation or tumors.
2. Symptoms: The primary symptom of erythema ab igne is a patch of redness on the skin, often with a reticulated or lace-like pattern. Other symptoms may include itching, burning, or a sensation of warmth in the affected area.
3. Risk Factors: Individuals who use heating pads or hot water bottles frequently, or those who have occupations that involve prolonged exposure to heat, are at a higher risk of developing erythema ab igne.
4. Diagnosis: A dermatologist can diagnose erythema ab igne by examining the characteristic skin changes and taking a medical history. In some cases, a skin biopsy may be performed to rule out other conditions.
5. Prevention: The best way to prevent erythema ab igne is to avoid prolonged exposure to heat sources. If you need to use heating pads or other heat-emitting devices, it is important to follow the manufacturer's instructions and limit the duration of use.

Erythema ab igne is a benign condition that usually resolves on its own once the source of heat is removed. However, in some cases, it may persist or cause complications. If you notice persistent redness, changes in skin texture, or any concerning symptoms, it is recommended to seek medical attention for further evaluation and management.
