Large Asymptomatic Schwannoma of the Tongue: An Unusual Case Report With Clinical, Radiologic, and Histopathological Correlation.

Schwannomas of the oral cavity are rare benign tumors, with the tongue being the most frequently affected site. This case describes a 22-year-old male presenting with a large, well-circumscribed mass on the dorsum of the tongue that remained entirely asymptomatic despite its considerable size. Clinical examination and non-contrast computed tomography revealed a localized hypodense lesion without infiltration. Complete transoral excision was performed, and histopathological analysis demonstrated classic Antoni A and B patterns with Verocay bodies, confirming the diagnosis of schwannoma. Postoperative healing was uneventful, with no functional deficits or recurrence during follow-up. This case highlights the importance of considering schwannoma in the differential diagnosis of tongue masses, as the clinical features may resemble fibroma, neurofibroma, or other benign soft-tissue tumors. Early identification and complete surgical removal ensure an excellent prognosis and preservation of tongue function.
