Secondary Oral Tuberculosis in HIV-Negative Patient

Oral manifestations of tuberculosis (TB) are exceedingly uncommon and are usually secondary to pulmonary TB. The development of extrapulmonary TB is mainly facilitated by immunosuppression. The oral manifestations of TB can be highly variable and non-specific therefore they can cause difficulties in diagnosis and delay in instituting the appropriate treatment. This article describes an infrequent case of secondary oral TB in an adult HIV-negative patient. The aim of this case report was to emphasize the importance of considering TB in the differential clinical diagnosis of ulcers affecting the oral mucosa.
