We describe a female patient with continuous use of a laptop computer on exposed legs for 6 months and consequent development of reticulated hyperpigmentation at the area. Histopathological examination revealed epidermal atrophy, collagen fragmentation, and vacuolar changes in the basal layer, among other signs. We consider this case to be a modern cause of erythema ab igne.79-80engHot temperatureHyperpigmentationInfrared raysArtigo10.1590/abd1806-4841.20165139S0365-05962016001100079Acesso aberto2-s2.0-85026324639S0365-05962016001100079.pdf
