La tuberculose primitive ORL extraganglionnaire

Abstract

Objectives

The aim of this sinusonasal study was to study several locations of ENT extranodal tuberculosis.

Material and methods

Our study focused on eight cases of tuberculosis in the cervicofacial region gathered in the ENT department of the Rabat Specialization Hospital (Morocco) between August 2004 and August 2006. They comprise two cases of rhinopharyngeal tuberculosis, two cases of tuberculosis, two cases of endobuccal tuberculosis (mandibular and lingual locations), and two cases of glandular tuberculosis (thyroid and parotid locations).

Results

These locations are rarely affected by tuberculosis. The clinical signs as well as radiology and endoscopy are not specific. The final diagnosis is based on histology. Bacillus cultures are necessary when caseum tuberculosis is not found, causing problems of differential diagnosis with granulomatous and malignant lesions. PCR provides quick bacterial antigen detection when cultures are negative. The treatment provides a quick and complete recovery while recurrences are infrequent.

Conclusion

ENT tuberculosis is rare if excluding the nodal locations. It should be mentioned as a differential diagnosis, especially in endemic areas. Most often, this is a surprise diagnosis.
