A case of neurilemmoma in the mandible

A case of neurilemmoma located in the mandible of an 11-year-old boy is presented with clinical findings as well as histochemical and electronmicroscopic features of the tumor. The histopathologic examination in the light microscope revealed that most of the tumor tissue was composed of typical neurilemmoma of Antoni Type A, with a few Antoni Type B. Ultrastructural findings support the concept that neurilemmoma may be derived from the Schwann cells of the nerve sheath but could not be differentiated from neurofibroma.
