title: Eosinophilic annular erythema.
abstract: Eosinophilic annular erythema is a rare benign recurrent disease, originally described in children, characterized by the recurrent appearance of persistent non-pruritic, urticarial annular lesions. Histologically a perivascular infiltrate composed of lymphocytes and abundant eosinophils in the dermis is exhibited. We report the case of a 15-year-old boy who presented with a 4-year history of recurrent flares of erythematous annular plaques on the trunk and extremities. The lesions resolved spontaneously after 3-5 weeks with no accompanying signs. A biopsy showed a mainly perivascular lymphocytic infiltrate with numerous eosinophils in the dermis.
