Oral tuberculosis in an asymptomatic pulmonary tuberculosis

Tuberculosis (TB) has been a worldwide health problem for centuries. It most commonly affects the lungs, but rare oral manifestations of TB have been reported. The aim of this paper is to present a case of painful erythematous lesion of oral cavity in undiagnosed asymptomatic pulmonary tuberculosis. This case is unusual in that the appearance of the painful oral lesion caused the patient to seek professional care and was concurrent with quiescent pulmonary disease.
