Abstract
A case of tuberculosis of the gingiva in a 54-year-old man with active pulmonary tuberculosis is described. Intraoral examination revealed irregularly shaped ulcers in the right maxillary and left mandibular gingiva. Oral tuberculosis is considered an uncommon lesion with various characteristics. It is often difficult to distinguish oral tuberculosis from other conditions, such as carcinomas. In our patient, a biopsy was performed under a clinical diagnosis of a malignant tumor. The pathological findings suggested tuberculosis of the gingiva. A chest X-ray examination showed extensive active pulmonary tuberculosis, and cultures of the sputum showed tubercle bacilli. Treatment with INH, RFP, and EB was effective; the pain and ulceration in the gingiva disappeared within 3 weeks
