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.<\/jats:p>","DOI":"10.1136\/bcr-2022-253868","type":"journal-article","created":{"date-parts":[[2023,8,28]],"date-time":"2023-08-28T00:40:25Z","timestamp":1693183225000},"page":"e253868","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Submandibular nodal schwannoma: where did it come from?"],"prefix":"10.1136","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3533-6535","authenticated-orcid":false,"given":"Siti Farhana","family":"Abdul Razak","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology - Head and Neck Surgery, Hospital Queen Elizabeth, Kota Kinabalu, Malaysia"},{"name":"Department of Otorhinolaryngology, Head and Neck Surgery, Faculty of Medicine, Universiti Kebangsaan Malaysia, Bangi, Selangor, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hardip Singh","family":"Gendeh","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology - Head and Neck Surgery, Universiti Kebangsaan Malaysia, Bangi, Selangor, Malaysia"},{"name":"Hospital Canselor Tuanku Muhriz, Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anuar","family":"Idris","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology - Head and Neck Surgery, Hospital Queen Elizabeth, Kota Kinabalu, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2023,8,27]]},"reference":[{"key":"2025082804271718000_16.8.e253868.1","doi-asserted-by":"crossref","DOI":"10.1177\/2632010X19829239","article-title":"Cervical lymph node Schwannoma-an unexpected diagnosis","volume":"12","author":"Silvestre","year":"2019","journal-title":"Clin Pathol"},{"key":"2025082804271718000_16.8.e253868.2","doi-asserted-by":"publisher","DOI":"10.3171\/2010.8.JNS091900"},{"key":"2025082804271718000_16.8.e253868.3","doi-asserted-by":"crossref","first-page":"34","DOI":"10.1007\/BF02968752","article-title":"Schwannoma of the nose and Paranasal sinuses","volume":"55","author":"Hazarika","year":"2003","journal-title":"Indian J Otolaryngol Head Neck Surg"},{"key":"2025082804271718000_16.8.e253868.4","unstructured":"Chen CW , Tsuang YH , Wong CC . n.d.
