Discoid lupus is characterized by erythematosus lesions limited to the skin, covered by adherent white scales, which rise at places more exposed to the sun. A case of a 26 year-old woman, who was suffering for months from redness and burning of the eyes, and was been treated for blepharitis without resolution is reported. On the eyelids exam, ulcerated lesions were found, that were diagnosed as discoid lupus by immunofluorescence. When faced with chronic lesions on the eyelids that do not respond to medical treatment, even if the ancillary exams are normal, the incisional biopsy must be performed to elucidate the diagnosis and, if necessary, immunofluorescence should be done as well.
