Key Points about Erythema ab igne:

  1. Definition: Erythema ab igne is a skin condition caused by prolonged exposure to infrared radiation or heat, leading to a reticulated, erythematous, and hyperpigmented pattern on the skin.
  2. Causes: It is commonly seen in individuals who are exposed to chronic heat sources, such as from heating pads, laptops, or open fires. It can be exacerbated by the use of heating devices for pain relief.
  3. Symptoms: Symptoms include a reticulated (net-like) reddish-brown pigmentation on the skin, often accompanied by itching or mild discomfort. Long-term exposure can lead to permanent skin changes and increased risk of squamous cell carcinoma.
  4. Diagnosis: Diagnosis is made clinically by observing the characteristic skin changes and identifying the source of heat exposure. In chronic cases, a skin biopsy may be required to rule out malignancy.
  5. Management: Management involves discontinuing the source of heat, using emollients, and treating any itching with topical corticosteroids if needed. Long-term follow-up may be necessary to monitor for any malignant transformation.
  6. Complications: Chronic exposure can result in persistent hyperpigmentation and, in rare cases, the development of squamous cell carcinoma in the affected area.
