Isolated Extra-Pulmonary Tuberculosis in ENT: A Commonly Missed Diagnosis

Tuberculosis (TB) constitutes 15-20% of TB cases in general practice among HIV-negative adults in India. The head and neck region provides an impressive field of research because of its varied presentations and different sites of involvement. TB may often mimic malignancy and is misdiagnosed, which leads to an unnecessary delay in diagnosis. Through this study, we aim to draw focus on the various ways in which isolated extrapulmonary TB manifests in today's clinical practice in the head and neck region. Prospective analysis of 60 patients diagnosed with TB in a simple random sampling over 1 year. The period of study was from July 2022 to June 2023. All those patients who presented to the ENT OPD of Civil Hospital of Asarwa. Patients with complete clinical data were included in the study. In our study patients in the 3rd and 4th decade of life were most commonly affected and a male preponderance of the disease was seen. The most common presentation of EPTB in the head and neck region is cervical lymphadenitis, followed by tuberculous otitis media and laryngeal TB. Each of these has a characteristic clinical presentation that helps to identify this disease. Fine needle aspiration cytology is a very efficient cytopathological examination method that helps in the diagnosis of the disease. Special care should be taken in patients in whom other routine conventional medical and surgical therapy fail to show the desired outcome. Special care and a high degree of suspicion are needed to diagnose extrapulmonary TB. Once rightly diagnosed, it will prevent the progression of the disease and its complications.
