Schwannomas are benign encapsulated tumors that proliferate from Schwann cells, commonly arise from the roots of spinal, cranial, facial, neck and extremity nerves. These lesions account for about 1% of all head and neck tumors. In the oral cavity, the tongue is more affected. Tumors usually present as a firm, asymptomatic, solitary and well-defined mass. Its etiology is unknown. Diagnostic investigation may include computed tomography, ultrasonography and magnetic resonance imaging. The treatment of choice is surgical excision, and prognosis is good. Female patient, Caucasian, 24 years old, complaining of tongue injury. On physical examination, a mass was observed in the region of the right dorsum of tongue, it was sessile, hardened, measuring about 7 mm in the largest diameter and with a similar color to that of healthy tissue, without painful symptomatology. No changes were observed in the panoramic radiograph. Surgical excision was performed under local anesthesia and the histopathological examination of the tumor revealed a schwannoma compatible lesion. Schwannoma of the tongue is a relatively rare tumor of the head and neck. Transoral resection allows the complete removal of this tumor with a low rate of relapse and with unlikely possibility of malignant transformation.
