Lingual Tuberculosis Associated with Abdominal Lymph Node Tuberculosis in a 10-year-old Immunocompromised Child: A Rare Entity

Oral tuberculosis (TB) is a rare form of extrathoracic TB and only few cases have reported in children. It is usually associated with pulmonary TB. A 10-year-old malnourished girl presented to us with complaints of fever and an oral ulcer for 25 days. Oral examination revealed a large irregular ulcer present over the dorsal surface of the tongue. A biopsy of the ulcerated lesion revealed epithelioid cell granulomas. Abdominal ultrasonography revealed multiple conglomerated lymph nodes in the mesentery and retroperitoneum. Cartridge-based nucleic acid amplification test detected Mycobacterium tuberculosis DNA in the tissue sample. Here, we describe a case of lingual TB associated with tubercular mesenteric lymphadenopathy in an immunocompromised girl who was successfully treated with 6 months of antitubercular therapy.
