Abstract
Jaw tumours in children occur infrequently and diagnosing these lesions and predicting their biological behaviour are difficult. Some of them are not diagnosed correctly at the initial stages as having a neoplasm and are wrongly treated for infections by antibiotic administration. Ameloblastoma is a common and aggressive odontogenic epithelial tumour. It has an aggressive behaviour and recurrent course, and is rarely metastatic. Ameloblastoma represents 1% of all tumours and cysts that involve the maxillomandibular area and about 10% of the odontogenic tumours. We are presenting a case report of a large and aggressive tumour in a 9 year old young female patient who was diagnosed as plexiform Ameloblastoma and was managed by hemi mandibulectomy and reconstructed with condylar recon plate and free iliac crest bone graft
