Tuberculids are cutaneous immunologic reactions to the presence of tuberculosis, which is often occult elsewhere in the body. A wide range of skin disorders has been interpreted as tuberculids in the past. Currently, however, only three entities are regarded as true tuberculids: papulonecrotic tuberculid, erythema induratum and lichen scrofulosorum. Patients with lichen scrofulosorum have a strongly positive tuberculin reaction and an excellent response to treatment with antituberculous drugs.
