Intraosseous schwannoma of the mandible : A case report

Abstract

A 70‑year‑old man was referred to our department with the chief complaint of pain and swelling in the right posterior mandible. Panoramic radiography disclosed a large unilocular radiolucent lesion with distinct borders involving the right mandibular body and ramus extending from the second molar to the upper portion of the ramus. A complete excision was achieved by removing the tumor with the inferior alveolar nerve from the right mandible. Histologically Antoni‑A tissue was the predominant microscopic pattern but it occasionally alternated with Antoni‑B areas. Immunohistochemical staining for S‑100 proteins showed diffusely positive findings. An examination confirmed a diagnosis of an intraosseous schwannoma of the mandible.
