Abstract
The extra nodal tuberculosis is a rare disease in Ear, Nose and Throat. The aim of this work is to study the epidemiological, clinical, therapeutic profiles of rare locations of ENT extra nodal tuberculosis.
This is a retrospective study between June 2003 and June 2019, including 29 cases of ENT extra nodal tuberculosis.
There were 6 cases of laryngeal tuberculosis, 5 cases of nasopharyngeal tuberculosis, 5 cases of salivary gland tuberculosis, 3 cases of tonsillar tuberculosis, 1 case of tuberculous retropharyngeal abscess, 3 cases of nasal tuberculosis, 3 cases of tuberculosis of the middle ear, 1 case of thyroid tuberculosis, 1 case of tuberculosis of the bony palate, and 1 case of mandibular tuberculosis.
All ages were affected with a predominance of young adults. The clinical signs, as well as radiological or endoscopic examinations, were not specific. The diagnosis was based on histology and/or bacteriology. Antibacillary therapy was instaured in all cases.
Extra nodal tuberculosis in ENT is rare. It is dominated by the laryngeal location. It must be considered as a differential diagnosis in front of any atypical symptoms, particularly in endemic countries.
