FERREIRA, Sara et al. Old condition caused by modern technology: Erythema ab igne. []. , 23, 1, pp.32-34. ISSN 0872-0754.

Introduction: Erythema ab igne is a rare reticular pigmented dermatosis, caused by prolonged and repeated exposure to heat. Multiple heat sources have been reported to cause this condition, as fire or stove in proximity with the skin. Case report: We report a case of a diabetic teenager with erythema ab igne induced by a laptop computer. Conclusions: Laptop induced erythema ab igne is an underdiagnosed clinical entity. In the future maybe it will be more frequent due to the improper use of these devices. The possible irreversibility of skin lesions and the potential severe complications reinforce the need to be aware for this disease.
