Abstract

Cutaneous tuberculosis (CTB) is an uncommon small subset of extrapulmonary tuberculosis, comprising 1–1.5% of all extrapulmonary tuberculosis manifestations, which manifests only in 8.4–13.7% of all tuberculosis cases. Lupus vulgaris (LV) and tuberculosis verrucosa cutis (TBVC) are forms of reinfection tuberculosis and often occur in presensitized patients, by exogenous inoculation. We report two cases of cutaneous tuberculosis at unusual sites. A 35-year-old female having a forehead lesion for 2 years was diagnosed as having tuberculosis verrucosa cutis and another 16-year-old girl with lesion in left axilla for 10 years was proven to have lupus vulgaris. The delayed diagnosis was possibly due to lower clinical suspicion due to the presentation of CTB at unusual sites. This highlights the importance of keeping TB as an important differential as misdiagnosis or delayed diagnosis of this entity can lead to prolonged morbidity.
