Coexistence of Lupus Vulgaris and Scrofuloderma in an Immunocompetent Patient: A Rare Presentation

Tuberculosis (TB) may involve cutaneous tissue in approximately 0.1%–0.5% of the cases. There are various morphological presentations of cutaneous TB such as lupus vulgaris (LV), scrofuloderma, TB verrucosa cutis, and tuberculids. Usually, a single form is observed in an individual, but coexistence of the multiple forms has been rarely reported in the literature. These concurrences may be considered an interesting immunological phenomenon as two immunologically different poles are occurring simultaneously. We present a case of LV and scrofuloderma in the same patient at different sites.
