[An uncommon localization of upper respiratory-digestive tract tuberculosis: the cavum].

On the basis of a personal case, the authors recall the features of tuberculosis in the cavum. These lesions can resemble malignant tumours of the rhino-pharynx and they are part of the differential diagnosis. In particular, the authors stress the existence of rhino-pharyngeal tuberculosis with very few symptoms, which need to be investigated routinely in the context of a survey of proven pulmonary tuberculosis.
