Úlcera lingual como manifestação de tuberculose sistêmica : relato de caso

Abstract

Tuberculosis is a chronic infectious disease caused by mycobacterium tuberculosis. Oral lesions of tuberculosis, although uncommon, can be observed and are characterized as chronic and painless ulcers. The aim of this paper is to report a case report of a male patient with tuberculosis in the mouth. The patient sought the stomatology service of the Hospital Municipal Rocha Maia, RJ, Brazil, with the main complaint of difficulty eating and hoarseness, as well as cough and loss of appetite. Thorax tomography was requested, showing areas of ground-glass opacity and nodular lesion in the lung. In the intrabucal physical examination extensive ulcerated lesion in the belly and lateral border of the tongue and floor of the mouth, painful and hardened edge is observed. On smear examination, positivity for mycobacterium tuberculosis is noted. In the face of all findings, an incisional biopsy was performed, and histopathological examination revealed a diagnosis of tuberculosis. The proposed treatment was 2RHZE and 4RHb in the maintenance phase being 3 tablets a day. This report shows the importance of a good medical history and thorough clinical examination by the dentist considering that oral tuberculosis injury is a differential diagnosis for squamous cell carcinoma and other infectious diseases.
