Lichen scrofulosorum: An uncommon manifestation of a common disease.
Tuberculid is a cutaneous immunologic reaction to the presence of tuberculosis (TB), which is often occult, elsewhere in the body or their fragments released from a different site of manifest or past tuberculous infection. These eruptive lesions are due to hematogenous dissemination of bacilli in a host with a high degree of immunity against Mycobacterium tuberculosis. Although rare, these specific lesions are important diagnostic markers of TB. Lichen scrofulosorum (LS) is one of the recognized tuberculids, usually seen in children and young adults. We report a female who was diagnosed with LS and was treated appropriately. This case report highlights the uncommon, easily misdiagnosed but readily treatable case of LS and emphasizes its early diagnosis, detection, and treatment of otherwise an occult systemic TB in young patients.
