RESUMEN
Mandibular aggressive central giant cell granuloma is a rare non-neoplastic giant cell tumour characterised by pain, bone destruction, tooth root resorption, jawbone cortical perforation, and high recurrence rate. This is a case of a 10-year-old boy who presented to the Dental Surgical outpatient clinic of University of Uyo Teaching Hospital with a three-year history of left jaw swelling. The clinical diagnosis was fibrous dysplasia of the left hemi-mandible. Consequently, left hemi-mandibulectomy was performed, and subsequent histopathological diagnosis was aggressive central giant cell granuloma of the mandible. This article presents this rare diagnosis and explores its classification, aetiopathogenesis, clinico-pathological features and management.
