Intraosseous Schwannoma of the Mandible

Abstract

Schwannoma (neurilemmoma) is a benign neoplasm originated from the neural sheath and occurring most frequently in maxillofacial region. Intraosseous schwannomas are rare. The mandible is the most common site of occurrence for these lesions. We report a rare case of Intraosseous neurilemmoma of the mandible, with an emphasis on clinical, radiographic and pathological findings. The tumor, located mainly in the ramus region, presented as a soft tissue mass in the oral cavity, Multilocular, well-defined, and radiolucent lesion on plain radiography. Dilatation of the mandibular canal was identified. Plain radiography partly helped to identify the solid nature of the tumor. A biopsy was necessary to make the final diagnosis because of the relatively nonspecific nature of the lesion. The lesion was surgically removed and no evidence of recurrence was observed after 6 months.
