Pediatric Primary Tuberculous Osteomyelitis of the Mandible Mimicking Parotitis

Tuberculosis (TB) is a worldwide public health problem; however, primary tuberculous osteomyelitis involving the mandible is extremely rare. Here, we report a 14-year-old boy who presented with a recurrent, generalized swelling of the cheek in the right side, mimicking parotitis. Fine needle aspiration cytology (FNAC) from the swelling was inconclusive. Contrast-enhanced computed tomography (CECT) of the head and neck revealed an osteolytic lesion of the mandible with a surrounding abscess. An intraoral incisional biopsy of the tissue showed a granulomatous lesion. The patient was started on anti-tubercular therapy (ATT) for six months. Our patient's presentation underscores the clinical difficulty in establishing a diagnosis and considering tuberculous osteomyelitis in the differential diagnosis.
