Oral manifestations of tuberculosis (TB) are not so frequent, and the lesions may emerge in immunosuppressed patients as a secondary expression of pulmonary TB. The following two case reports focus on the clinical challenge of early diagnosis of painful ulcerative lesions in oral mucosa that occurred in two senior females, both human immunodeficiency virus negative patients, however receiving immunosuppressing medication. The patients did not present classic symptoms of TB. Nevertheless, based on different studies, extrapulmonary TB should still be considered as differential diagnosis for the oral mucosa lesions developed by these patients.
