Schwannomas are benign tumors that originate in the myelin sheath of neurons, more specifically in Schwann cells. Between 25-45% of these tumors occur in the topography of the head and neck, and may appear in various anatomical sites –oral cavity, larynx, pharynx, parapharyngeal space, and others. The main complaints are a painless, slow-growing mass and symptoms related to compression of nearby structures by the lesion. Its diagnosis is almost always given with the anatomopathological study after resection of the lesion, since fine-needle punctures usually show indeterminate results and imaging tests such as computed tomography (CT) and magnetic resonance imaging (MRI) cannot confirm this diagnosis, although they bring important information about location, size and contact with adjacent structures. Treatment, if there is no contraindication, is through surgical excision of the tumor. In this report, we present the case of a 47 year-old female patient complaining of left submandibular nodulation, whose diagnosis of schwannoma was only given after a left submaxillaryectomy, through the pathological examination.
