Aim

Schwannoma is a benign neuroectodermal tumor of the nerve sheath or myelin sheath formed by Schwann cells. Approximately between 25 and 48% of the cases are located in the cervicofacial territory, especially in the soft tissues of this region. They can be classified into peripheral and intraosseous schwannomas, the last one can also be reported as central. Intraosseous schwannomas are rare, constituting less than 1% of schwannomas present in the region and less than 0.2% of all primary bone tumors. This publication aims to report a clinical case of mandibular intraosseous schwannoma, reviewing clinical, radiographic and anatomopathological aspects. Intraosseous schwannoma is a rare entity, or at least is under a condition of underreport in Argentina, so this case is a rarity.

Clinical case

A 30-year-old patient, referred to the Buccomaxillofacial Surgery and Traumatology service of the “Parmenio Piñero” Hospital of Ciudad Autónoma de Buenos Aires by her dentist, because of a radiographic finding during a routine check. An incisional biopsy was performed, the anatomopathological result of which was compatible with the diagnosis of intraosseous schwannoma. A complete enucleation was performed under local anesthesia. Finally, the patient evolved without complications.
