Schwannoma is a benign peripheral nerve sheath tumor originating from Schwann cells. Its occurrence in the tongue is rare. We report the case of a 19-year-old patient presenting with a painless, slowly enlarging mass on the mobile portion of the tongue. MRI revealed a well-defined, encapsulated lesion. The mass was completely excised surgically, and histopathological examination confirmed the diagnosis of a benign schwannoma. The postoperative course was uneventful, with no recurrence observed during follow-up.
