title: Oral tuberculosis.
abstract: Tuberculous lesions of the oral cavity have become so infrequent that it is virtually a forgotten disease entity and may pose a diagnostic problem. Fifteen patients with conditions that were histologically diagnosed as oral tuberculosis were reviewed. All were men ranging in age from 29 to 78 years. The most common clinical presentation was odynophagia with a duration from less than 1 week to several years. The most frequently affected sites were the tongue base and gingiva. The oral lesions took the form of an irregular ulceration or a discrete granular mass. Mandibular bone destruction was evident in two patients. Two patients had a fever, and four had cervical lymphadenopathy. Eight cases were clinically suspicious for malignancy before biopsy. Only four patients had a history of tuberculosis, but 14 of the 15 patients were later found to have active pulmonary tuberculosis. Acid-fast bacilli were demonstrated in all patients. Tuberculosis should be considered in patients with an inflamed ulcer lesion. A biopsy specimen for histologic study, acid-fast stains, and cultures should be obtained for confirmation and differential diagnosis with other conditions. If a tuberculous lesion is suspected, a chest radiograph is indicated to investigate the possibility of pulmonary involvement.
