Schwannoma of the oral tongue
Schwannomas are benign tumors arising from Schwann cells that affect the peripheral or central nerves. We report the case of a patient presented with a swelling of the tongue. The diagnosis was performed through imaging exams, videolaryngoscopy and magnetic resonance imaging (MRI), and incisional biopsy. The patient underwent complete transoral resection of the lesion. Schwannomas are rarely found in the oral cavity, with 46 cases described in the tongue. They present in several ways, from painless nodules to bulky masses with compressive symptoms. Complete surgical excision is the treatment of choice. These tumors show rare recurrence if completely excised.
