We report on a 32-year-old female with a 3-year history of an asymptomatic
erythema of the forehead. The lesion had a linear distribution following th
e lines of Blaschko. Histopathological findings and direct immunofluorescen
ce allowed to establish the diagnosis of cutaneous lupus erythematosus. Tre
atment with local corticosteroid and antimalarial agents given for 2 months
resulted in a complete remission.
