Introduction: Oral tuberculosis is a chronic granulomatous disease caused by Mycobacterium tuberculosis. According to the World Health Organization (WHO), nearly 2 billion people are infected with tuberculosis. Objective: To report a rare case of oral tuberculosis with ulcers at two different sites. Materials and methods: In order to emphasize the need to consider tuberculosis in the differential diagnosis of non-healing ulcers of oral cavity and the role of oral physician in preventing the spread of such lesions, this article presents a case of oral ulcers at two different sites, diagnosed as tuberculosis ulcer. Results: Oral cavity, which is considered to be a mirror of systemic health, rarely manifests tuberculosis. With increasing number of tuberculosis cases and unusual form of the disease in the oral cavity, the cases are likely to be misdiagnosed. Conclusion: An oral clinician should have a thorough knowledge of tuberculosis and its oral manifestations.

Introdução: A tuberculose oral é uma doença granulomatosa crônica causada pelo Mycobacterium tuberculosis. Segundo a Organização Mundial da Saúde (OMS), cerca de 2 bilhões de pessoas estão infectadas com tuberculose. Objetivo: Relatar um caso raro de tuberculose oral com úlceras em dois locais diferentes. Materiais e métodos: Para realçar a necessidade de considerar a tuberculose sob o diagnóstico diferencial das úlceras não curadas da cavidade oral e o papel do dentista na prevenção da propagação de tais lesões, este artigo apresenta um caso de úlceras orais em dois locais diferentes, diagnosticados como úlcera de tuberculose. Resultados: A cavidade oral, considerada como um espelho da saúde sistêmica, raramente manifesta a tuberculose. Com um número cada vez maior de casos de tuberculose e a forma não usual da doença na cavidade oral, os casos são frequentemente diagnosticados erroneamente. Conclusão: O dentista clínico geral deve ter um conhecimento profundo da tuberculose e de suas manifestações orais.

Primary tuberculosis of tonsil and posterior oropharyngeal wall.

Pharyngeal tuberculosis is rare and usually occurs in association with primary pulmonary disease. Primary tuberculosis involving the palatine tonsils and the posterior oropharyngeal wall is still a rare clinical entity. We report one such case of primary tuberculosis involving both the palatine tonsils and the posterior oropharyngeal wall in a 22 year-old male. The patient responded to anti-tubercular treatment with complete disappearance of lesion and no sign of recurrence on one year follow-up. The final diagnosis was based upon histopathological report.

Tuberculosis of oral cavity.

Tuberculous involvement of oral cavity is very rare. A 34-year-old male presented with non-healing ulcer at upper lip mucosa. Biopsy from ulcer revealed tuberculous lesion. He also had asymptomatic pulmonary tuberculosis diagnosed during work up for primary site of the disease.
