Bone Tumor Diagnosis and Treatments

This study reports a case of mandibular ameloblastoma that has exceeded the midline. A 62-year-old female patient presented with painless swelling complaint in body region and left mandibular symphysis. The clinical examination showed intact mucosa and normal color; facial asymmetry left and dysphagia. The panoramic radiographies suggested image circumscribed radiolucent unilocular in the left mandible body with a length exceeding symphysis and parasymphysis to the opposite side. CT (CT) scan showed hypodense image in the region was to break the buccal bone plate. The incisional biopsy generated histologic sections that revealed odontogenic tumor fragments in the form of nests and strands with peripheral columnar cells similar to ameloblasts, confirming the diagnosis of ameloblastoma unicystic. Marsupialization was performed for tumor decompression in progress, preservation and preparation for subsequent enucleation surgery. Bilateral involvement that goes beyond the midline is unusual in odontogenic tumors, especially in ameloblastoma.
