Primary tuberculosis of the vallecula and pyriform sinus: a case report and review of literature.
BACKGROUND
Tuberculosis (TB) is a relatively prevalent infectious disease caused by a bacterium called mycobacterium tuberculosis. It primarily involves the lungs, but it can also affect other organs causing a variety of symptoms.


METHODS
In this report, a rare case with primary involvement of pyriform sinus and vallecula due to tuberculosis in a 74-year-old woman who complained of odynophagia for 6 months, is reported. There were no clinical or radiological pulmonary findings.


CONCLUSIONS
The authors point out the epidemiological importance of tuberculosis and the need for more suspicion when dealing with uncommon lesions to make an early diagnosis.
