Erythema ab igne (EAI) is a red-brown net-like hyperpigmentation due to repetitive exposure to submaximal heat over a long period of time. This rash is typically seen on the anterior lower legs of people who sit in front of open fireplaces or coal stoves and on the trunk of patients with chronic disorders who seek pain relief by long-term use of hot-water bottles or heating pads. EAI can not only be a diagnostic sign for underlying internal diseases including malignant tumors but can also give rise to cutaneous malignancies. We report on a 75-year-old female patient who developed several thermal keratoses and squamous cell carcinomas at the site of erythema ab igne caused by chronic heat exposure over several years. 相似文献

Erythema ab igne (EAI) is an asymptomatic dermatosis that develops in response to chronic exposure to low‐grade heat. Characteristic findings on histopathology include epidermal atrophy, dermal elastosis, atypical histiocytes, and melanin and hemosiderin deposition. Reactive endothelial changes and prominent vascular proliferation are variable. Keratosis lichenoides chronica (KLC) is a rare lichenoid hyperkeratotic dermatosis. Acanthosis with parakeratosis and a lichenoid interface dermatitis with lymphocytes, histiocytes, and plasma cells are characteristic findings of KLC. Although its etiology remains unclear, KLC has been reported to occur in response to heat. Herein, we report a case of EAI with features resembling KLC. 相似文献

Erythema ab igne (EAI) is a rare condition since the advent of central heating. Its incidence has been rising as heating sources are being used to treat chronic pain. Multiple activities that chronically expose patients to heating sources also have been documented with this condition. We present a case of EAI induced by the use of an electric blanket. 相似文献
