Worsening Lower Jaw Swelling and Pain in a Teenager: Differential Diagnosis and Management.

Giant cell granuloma is a rare, benign non-neoplastic, aggressive tumor that originates mainly from the maxilla and mandible. It affects all age groups and is more commonly seen in children. We describe a 17-year-old female that presented to the Pediatrics Emergency room with a history of right lower jaw pain. Examination revealed a bone-like buccal vestibular swelling on the lower right tooth, a bone-like lingual swelling, and a pink gingival overgrowth lesion. The biopsy of the lesion revealed a central giant cell granuloma. Tissue biopsy with histopathological examination is diagnostic and surgical excision is the gold standard of treatment.
