Malignant schwannoma of the gingiva.
A case of malignant schwannoma on the buccal-attached gingiva in the right mandible is described. There was no evidence of multiple neurofibromatosis and the tumor was totally excised. Numerous closely-packed spindle-shaped cells showing marked mitotic activity were seen. The recognizable pattern of neurilemmoma could be observed focally in a small area of the tumor. At two years follow-up, the patient has remained symptom-free with no signs of metastasis.
