Schwannoma corresponds to a benign neurogenic tumor, derived from neural crest cells. It accounts for approximately 5% of all benign soft tissue tumors. These are the most common cause of peripheral nerve neoplasms of the oral cavity and oropharynx representing 1%. Isolated or solitary neurofibromas of the oral cavity usually involve the tongue or the labial mucosa. They appear as soft, painless, slow-growing masses that are tender to depression or palpation. The case of a 40-year-old woman is studied because of the presence of painless swelling, slow, and progressive growth of the oral language. Complete removal of the lesion was performed and primary closure was performed. It had a satisfactory evolution, maintaining adequate sensory and sensory mobility and innervation.
