title: Concomitant lichen scrofulosorum and erythema induratum.
abstract: We describe a patient in whom two tuberculids, lichen scrofulosorum, and erythema induratum occurred simultaneously. The clinical and histopathologic features were characteristic and a Mantoux test showed a positive reaction. There was no extracutaneous focus of tuberculosis. Polymerase chain reaction for mycobacteria in the skin lesions was negative, but her lesions responded rapidly to antituberculous chemotherapy.
