An Unusual Extranodal Presentation of Mycobacterium Tuberculosis in the Upper Lip
Abstract:
Tuberculosis (TB) is a leading cause of morbidity and mortality worldwide, with a peak incidence in South-East Asia and Sub- Saharan Africa. A significant number of patients in the UK are affected. Extra-pulmonary TB presentation varies, and includes head and neck manifestations that can present on routine examination in the dental practice setting. We report an unusual case of extra-nodal TB in the upper lip, and provide some guidance to general dental practitioners on the presenting features of such lesions, and what to refer for further investigation where TB is included in the differential diagnosis. CPD/CLINICAL RELEVANCE: This case report highlights important factors in TB diagnosis, with particular emphasis on presenting features relevant to general dental practitioners, and informs on the accepted and current treatment regimen.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
