“…According to reports in the literature, the most common site of extracranial schwannomas in the head and neck is the parapharyngeal region: in fact, these are usually retro-styloid injuries in the carotid space that cause anterior displacement of the fat present in the pre-styloid parapharyngeal space, with bulging of the lateral wall of oropharynx. 12 , 13 , 14 , 15 Other sites in the head and neck, such as the submandibular region, paranasal sinuses, face, and oral cavity, are rare. 16 As for location, cases on the lateral aspect of the neck predominated, and most occurred in the parapharyngeal region.…”

“…Unencapsulation does not mean the tumor is malignant, it implies the aggressive nature of the tumor and makes it difficult for the surgeon to extract the tumor in Toto. Schwannomas can also undergo degenerative changes such as lipidization, cystic degeneration, necrosis, and angiomatous change with thrombi formation [2,8,10].…”

Schwannomas are neurogenic tumors arising from the Schwann cells present in the neural sheath of the myelinated nerves. These are benign tumors that can arise anywhere in the body. Schwannomas are rarely seen in the nose and paranasal sinuses representing <4% of all head-and-neck schwannomas. Surgical excision is the treatment of choice in these cases. Nasal polyps are common nasal cavity lesions which are usually inflammatory polyps. Schwannoma of the nasal cavity usually presented with headache, unilateral nasal obstruction due to mass obliterating the nasal cavity, and epistaxis. Here, we report the case of a 47-year-old female who presented with a mass in the left nasal cavity causing the nasal blockage.

“…Meanwhile, Gonzalvo et al have mentioned that the most common head and neck sites include the vestibular spine, subcutaneous and brachial plexus 2. The occurrence of schwannoma in paranasal sinus, submandibular space, oral cavity and cheek is uncommon according to Hazarika et al 3. Malignant transformation is very rare for schwannoma.…”

SummarySchwannoma, a type of benign neurological tumour arising from Schwann cells, is commonly seen in the head and neck region. However, the incidence of cervical lymph node schwannoma is extremely rare, with only two cases reported in the literature. Schwannomatosis is a disease characterised by a constellation of multiple schwannomas seen in a patient, guided by at least one confirmational histological diagnosis. This is a case of a painless progressively enlarging submandibular swelling which is confirmed as a schwannoma based on histology. The patient is also diagnosed with schwannomatosis as the patient has multiple neurological tumours. Nodal schwannoma has a good prognosis and no documentation of recurrence in the literature. It may arise from sympathetic nerves located within the lymph node.
