Erythema ab igne (EAI) has not been common since coal stoves have no longer been in general use for heating. Nevertheless, each winter several patients with macular-reticular skin lesions considered to be EAI are seen in our clinic. Correct diagnosis depends on awareness of the condition. 3 women, aged 17, 34 and 50, respectively, in whom EAI was induced by prolonged sitting close to an electrical heating device are presented. When this was discontinued the skin lesions disappeared. In the majority of reported cases of EAI the course was benign, similar to that in our patients in whom there were no additional related lesions. However, isolated cases of squamous cell carcinoma developing in patients with EAI have been described. In other cases the local heating which caused the EAI was applied for relief of pain and the appearance of EAI was the first clue to an underlying internal disease.
