Erythema ab igne: an old condition new again.

1,2 A case of EAI associated with the use of a space heater was reported by a 27-year-old healthy woman of South Asian background; she presented with a 3-month history of an asymptomatic rash on her lower legs, which was noticed 1 or 2 weeks after she began to use an electric space heater. The heater was placed approximately 30 cm away from the left side of her legs for 3-5 hours a day. The eruption began as reticulate erythematous patches on the lateral aspect of her left and the medial aspect of her right calf. She subsequently stopped using the heater and on presentation had nontender, reticulate, tan-brown patches with faint erythema in the above-mentioned areas. There was no evidence of telangiectasias, atrophy or nodules, and no systemic symptoms were reported.
