RT Journal Article SR Electronic T1 Primary tonsillar tuberculosis JF BMJ Case Reports FD BMJ Publishing Group Ltd SP bcr-2017-223634 DO 10.1136/bcr-2017-223634 VO 2018 A1 Swetha Sasikumar A1 Irfan Ismail Ayub A1 Senthil Kannan A1 Rajendiran Swaminathan YR 2018 UL http://casereports.bmj.com/content/2018/bcr-2017-223634.abstract AB Upper aerodigestive tract involvement with tuberculosis is relatively rare and may be seen in up to 2% of patients with pulmonary tuberculosis. Isolated tonsil involvement with tuberculosis is not commonly seen in clinical practice. We report a case of a 22-year-old postpartum mother who presented with odynophagia, fever, loss of weight and submandibular swelling of 3 months’ duration. Clinical examination revealed a submandibular node, and oropharyngeal examination revealed necrotic slough overlying an enlarged left tonsil. Fine-needle aspiration cytology of the node and histopathological examination of the left tonsillectomy specimen revealed necrotising epithelioid cell granulomas, and stain for acid-fast bacilli was positive in the latter. She was diagnosed with tonsillar tuberculosis and was started on antituberculous treatment following which she improved clinically. This case serves to demonstrate an uncommon presentation of primary tuberculosis and reminds us to consider tuberculosis also as a microbiological aetiology for tonsillitis.
