title: Schwannoma of the tongue-A common tumour in a rare location: A case report.
abstract: Schwannoma is a benign tumour that arises from Schwann cells of the peripheral nerve sheath, and is a common tumour of the head and neck. However, intraoral location is very uncommon (only 1% of all head and neck schwannomas). We report a rare case of lingual schwannoma in a 20-year-old male patient who presented with a small, slow-growing mass over the right lateral border of the tongue with 1 year of evolution and that became recently ulcerated. The patient underwent MRI examination and complete surgical excision. Histopathological and immunohistochemical examination confirmed the diagnosis.
