Tuberculous lymphadenitis: early diagnosis and intervention.

Tuberculosis (TB) is reported to be one of the most widespread systemic bacterial infectious diseases frequently triggered by Mycobacterium TB. It is anticipated to have a prevalence of approximately 8 million individuals each year, and 3 million individuals die of complications related with the ailment. We present a case of a 5-year-old female patient with a painless swelling in her left submandibular region. She was diagnosed with left submandibular TB lymphadenitis based on histopathology report. Extra pulmonary TB of the oral cavity and its associated structures are diagnostic challenge. Lesions are often slow developing, painless, and hence are primarily ignored. Although manifestations of TB are atypical in head and neck area, clinicians should integrate them in the differential diagnosis. A hasty diagnosis with well-timed treatment can thwart complications.
