Primary and secondary tuberculosis (TB) of the oral cavity is relatively rare and has largely become a forgotten diagnosis in oral lesions. This case report describes a refractory painless oral ulcer as secondary lesion of active primary lung TB in 40 years old patient, who never had any specific symptoms of pulmonary manifestation. The intraoral examination revealed an ulceration that is located in the buccal mucoa extending to the right lip commissure. The presence of tuberculosis was confirmed by histology. We emphasize the importance of considering tuberculosis in the differential diagnosis of oral lesions that affects the mucosa and the importance of early diagnosis and management.
