Case Report: A Case of Tuberculosis with Psoriasiform Lichen Scrofulosorum Exhibiting Koebner's Phenomenon followed by Scrofuloderma.

Abstract

Lichen scrofulosorum is the most common tuberculid in the Indian population and the second most common form of cutaneous tuberculosis. We discuss an uncommon presentation of lichen scrofulosorum, with psoriasiform morphology and koebnerization at tuberculin test site, associated with cervical lymphadenitis in a 17-year-old girl. Although the cutaneous lesions resolved completely after 3 months of antitubercular treatment (ATT), she developed scrofuloderma in the left cervical region at 4 months. In the absence of rifampicin resistance, ATT was continued for another 6 months, with no further evidence of disease activity. This case represents an infrequent occurrence of lichen scrofulosorum followed by scrofuloderma, which necessitated a prolonged course of first-line ATT.
