Primary Tuberculosis of Tonsils: A Case Report

Tuberculosis is one of the major causes of ill health and death worldwide. Isolated tuberculosis of tonsil in the absence of active pulmonary tuberculosis is a very rare clinical entity. A 10-year-male child presented with recurrent episodes of upper respiratory tract infections, with 2-3 occurrences per month for the past 6 years. On general physical examination, bilateral tonsils showed grade III enlargement and congestion. Posterior pharyngeal wall was clear. Examination of the chest was within normal limits. Histopathological examination of bilateral tonsils revealed caseating and noncaseating epithelioid cell granulomas with Langhans giant cells. Ziehl-Neelsen stain for acid fast bacillus was positive. Features were consistent with a diagnosis of tuberculosis of tonsils. Tuberculosis of the oral cavity is uncommon and lesions may be either primary or secondary. Early detection and intervention is essential for cure. Isolated and primary tuberculosis of the tonsils in the absence of pulmonary tuberculosis is a rare entity, which prompted us to report this case.
