An uncommon sighting--lupus vulgaris of the foot.

Lupus vulgaris (LV)is a progressive form of cutaneous tuberculosis (TB)that may occur in a patient with a moderate or high degree of immunity. The incidence of LV has declined with that in TB; it is relatively uncommon even in developing countries. LV commonly presents in the head and neck regions as flat plaques. Variants of LV form huge, soft, tumor-like forms with deep tissue and cartilage destruction resulting in deformities. The authors report a case of LV in a patient who presented with an ulcero-proliferative growth in the lower extremity, mimicking a malignancy.
