Treatment of extensive malignant schwannoma of the mandibular nerve.

This article describes a rare malignant schwannoma invading the left mandible in a 42-year-old man. The clinical presentation, inconclusive radiographic findings, and light microscopic histology are included. The appropriate surgical treatment could be determined only intraoperatively when frozen sections provided the exact tumor margins. The patient subsequently received adjuvant treatment by brachytherapy.
