Lichen scrofulosorum: A prospective study of 39 patients

Abstract

Lichen scrofulosorum is an uncommon but not rare cutaneous manifestation of tuberculosis. A high index of suspicion and awareness is required for diagnosis. Systemic tuberculosis is often associated with LS and a prior BCG inoculation does not protect against development of LS. Response to antitubercular treatment is good irrespective of the presence or absence of associated tubercular focus.
