title: Facial blaschkitis: case and review.
abstract: We report on a 15-year-old female with a 3-month history of a pruritic, erythematous cutaneous eruption on the right cheek and perioral area. The lesion had a linear distribution following the lines of Blaschko. Histopathological findings and direct immunofluorescence were compatible with chronic cutaneous lupus erythematosus (LE). Treatment with topical steroids and systemic antimalarial agents over 2 months showed hardly any improvement contrary to similar cases reported in the literature in the past. Histological findings move this case close to LE. However, the unusual clinical presentation as well as the resistance to antimalarial drugs do not fully allow to confirm this suspicion. Therefore, we recommend to call this new entity LE-like facial Blaschkitis of the adult.
