Acquired Thermal Telangiectasia

Widespread telangiectasia with a possible exogenous explanation

“…When searching the literature, we found a case report from the 1950 presenting heat-induced telangiectasia. 10 When reconsidering the whole picture of our patients' history and clinic, we find that heatinduced telangiectasia is a possible explanation of these patients' skin lesions (Fig. 1).…”

Malignant Change in Erythema ab igne

“…Any form of heat, if the exposure is long enough, would probably produce the disease, and there is some evidence that erythema ab igne has been provoked by gas and electric fires. It would almost seem as if the inhabitants of North America were not so prone to develop this type of reaction, for Danto and Maddin (1954) described the case of a woman in Vancouver who had developed what they termed " thermal telangiectasia" caused by an electric fire, an electric heating pad, and a car heater. This patient developed numerous discrete, pinhead-sized telangiectases on the posterior aspect of her legs, with no sign of byperpigmentation, freckling, or mottling.…”
