A rare clinical case: schwannoma of tongue

Chandra Veer Singh, Sheetal Radia, Saalim Sheikh, Vijay Haribhakti

Abstract


Schwannoma are slow growing tumours, which can arise from any peripheral nerve. 10% of schwannomas that occur in the head and neck region mostly originate from the vagus or sympathetic nervous system. Extracranial schwannomas in the head and neck region are rare neoplasm. Intraoral schwannoma are only 1% of the all head and neck tumours. Diagnosis is established by imaging studies such as magnetic resonance imaging or computed tomography, while FNAC is used to rule out other conditions. We report a rare case of lingual schwannomas generally present as a painless lump schwannoma of the tongue in a 27-year-old male complaining of asymptomatic swelling over a posterolateral surface of the tongue, treated by complete surgical excision. The diagnosis was established on the basis of clinical, histopathological, and immunohistochemical examination. We report a rare case of schwannoma over the posterolateral surface of tongue. Prognosis is good for the patient when this condition is correctly diagnosed as the condition rarely recurs after complete resection.
