A 68-year-old female presented with pain at the left side of the tongue since 1 month. Also a firm to soft 7 × 5 cm sublingual swelling of long-standing duration was seen. FNAC was inconclusive and contrast CT showed a sublingual swelling with mild-contrast enhancement.
Sublingual excision of the tumor was done under general anesthesia and the tumor enucleated. No complications were seen and the recovery was uneventful. Histopathological report came as benign schwannoma and immunoreactive to S- 100 protein.
Most of the intraoral schwannomas are managed by complete surgical excision and recurrence are not reported. Malignant transformation is not seen in any of the intraoral schwannomas but definite preoperative diagnosis is necessary to avoid wide excision when the tumors can be easily enucleated without recurrence.
