A case of LEDC is reported, with clinic, histopathological and immune-fluorescence studies. The injuries start suddenly on the face and neck with a capricious evolution, reaching a complete disappearance without leaving neither scar nor atrophy, returning in few time in zones normally not exposed to the sun, as subchin region, low neck zone and lateral aspects of the neck continuing on the level of the skin of the head. The clinic study of the injuries call to mind the form described by Gougerot in 1930 of his túmidus and by the evolution of the same, the forma described by Gougerot and Carteaud, denominating it "à eclipse".
