Intraosseous schwannnoma of the mandible: A case report
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. (Accepted on July 6, 2009)
