Oral mucosal ulceration: a manifestation of previously undiagnosed pulmonary tuberculosis.

BACKGROUND

Tuberculosis, or TB, is a chronic infectious disease that can affect any part of the body, including the mouth. Oral lesions may be the only finding of primary pulmonary TB, in which case proper diagnosis by dentists is vital.

CASE DESCRIPTION

The authors present a case in which the patient sought treatment for a painful oral lesion. A histopathologic examination revealed characteristics of TB. Subsequently, pulmonary lesions were detected, and a diagnosis of pulmonary TB was confirmed. The patient underwent antituberculosis therapy, and his oral and systemic conditions improved rapidly.

CLINICAL IMPLICATIONS

Although oral manifestations of TB are rare, clinicians should be aware of their possible occurrence in their patient populations. Such awareness can help diagnose TB at an early stage, thereby preventing complications and potential contaminations.
