Summary

Schwannoma, 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.
