Erythema ab igne [dermatitis ab igne]
Clinical Classification Guidelines
Medical Intelligence & Overview
Erythema ab igne, also known as dermatitis ab igne, is a skin condition characterized by a distinctive, net-like pattern of redness and pigmentation. It develops as a response to repeated or prolonged exposure to heat sources such as heating pads, hot water bottles, or space heaters. Over time, the affected skin may show discoloration, pigmentation changes, and in some cases, skin thickening. Recognizing this condition is essential to prevent potential complications and to seek appropriate management.
Causes & Symptoms
Clinical Causes: Prolonged exposure to heat sources such as heating pads, electric blankets, or heating devices. Frequent use of hot water bottles or hot packs directly on the skin. Occupational exposure to heat in certain professions, like baking or manufacturing. Chronic use of inappropriately applied heating devices for therapeutic purposes. Repeated contact with hot surfaces or objects in everyday activities.
Key Symptoms: Reticulated (net-like) pattern of redness and pigmentation on the skin. Discoloration or brownish pigmentation in affected areas. Skin texture changes, including thickening or dryness over time. In some cases, mild itching or burning sensation. Development of hyperpigmentation that may persist even after heat exposure stops. In rare situations, skin ulcers or precancerous changes may occur if exposure continues long-term.
Diagnostic & Treatment
Diagnosis Path: Diagnosis is primarily clinical, based on a thorough examination of the skin and patient history of heat exposure. A healthcare provider looks for the characteristic net-like pattern of skin discoloration. Additional tests, such as skin biopsy, may be performed in unclear cases or if atypical changes suggest other skin conditions. Recognizing the pattern of symptoms alongside the patient’s history helps distinguish erythema ab igne from other dermatological issues.
Treatment Protocols: Management focuses on eliminating the source of heat to prevent further skin damage. The primary steps include:
