A Case of Schwannoma at Tongue

Schwannoma is a benign peripheral nerve sheath tumor. Although rarely found in the oral cavity, it is most commonly found on the tongue, followed by the palate, palate, buccal mucosa, and mandible. Because schwannoma of the base of the tongue is so rare, it is often not included in the differential diagnosis immediately, delaying identification and treatment. We report a case of schwannoma at the base of the tongue misdiagnosed as lingual thyroid, along with a literature review. A 28-year-old man presented with a tongue mass, which was first discovered a month ago. The preoperative diagnosis was lingual thyroid gland on physical findings and computed tomography findings. The permanent pathological report of the mass was schwannoma. After surgery, the patient had no problems with tongue function and wound healing.
