A Case of Erythema ab igne Containing Atypical Squamous Cells in Epithelium

Abstract

Erythema ab igne (EAI) is a chronic and recurrent dermatosis caused by long-time or excessive exposure to low levels of infrared radiation and various forms of heat. It is a rare condition today and multiple heat sources including heating pads, car heaters, electric space heaters and laptops have been reported to cause this condition. Although EAI has a good prognosis, it poses a risk for squamous cell and Merkel cell carcinomas. We present a woman diagnosed with EAI including extensive atypical squamous cells histologically caused by a radiant heater.
