Although cutaneous tuberculosis (TB) is a rare form of extra-pulmonary TB, lupus vulgaris is the commonest variant of cutaneous TB. We present a 14 year female with non-healing ulcer over the upper lip extending and destroying the collumela and part of anterior nasal septum. Histopathological examination revealed TB as a possible cause of the lesion. Identification of acid-fast bacilli on direct stained smears confirms the diagnosis of TB. Complete healing of the ulcer was achieved with anti-tuberculous regime leaving a residual fibrosis over the site of the ulcer.
