The growth pattern is usually slow, tending to clinical indolence. Primary pulmonary neuronal tumors are very rare, accounting for ~0.2% of all lung neoplasms, and are often misdiagnosed due to their nonspecific radiological features. A 50-year-old man presented with a large cystic mass in upper lobe of left lung discovered incidentally on chest X-ray during work up after a blunt chest trauma. Gross examination of the mass following surgical excision revealed a well-circumscribed, encapsulated creamy-gray cystic lesion with gelatinous material measuring 10.5\u2009\u00d7\u20096\u2009\u00d7\u20095.5\u2009cm, attached to a segment of lung. Microscopically, the tumor showed hypo- and hypercellular areas with proliferation of elongated wavy cells in a myxoid background which is characteristic of Schwannoma. Despite intrapulmonary schwannomas\u2019 rarity, it is essential to consider schwannomas in the differential diagnosis of pulmonary masses, particularly when clinical and radiological findings suggest a well-defined, encapsulated lesion.<\/jats:p>","DOI":"10.1177\/30502098251410398","type":"journal-article","created":{"date-parts":[[2025,12,31]],"date-time":"2025-12-31T09:32:40Z","timestamp":1767173560000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Intrapulmonary Schwannoma: A Rare Case Report and Review of the Literature"],"prefix":"10.1177","volume":"18","author":[{"given":"Elham","family":"EntezarAlmahdi","sequence":"first","affiliation":[{"name":"Department of Pathology, School of Medicine, Shiraz University of Medical Sciences, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mehdi","family":"Jamalpour","sequence":"additional","affiliation":[{"name":"Department of Pathology, School of Medicine, Shiraz University of Medical Sciences, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Parviz","family":"Mardani","sequence":"additional","affiliation":[{"name":"Thoracic and Vascular Surgery Research Center, Shiraz University of Medical Sciences, Iran"},{"name":"Department of Surgery, Shiraz University of Medical Sciences, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zahra","family":"Beyzaei","sequence":"additional","affiliation":[{"name":"Transplant Research Center, Shiraz University of Medical Sciences, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1009-0049","authenticated-orcid":false,"given":"Bita","family":"Geramizadeh","sequence":"additional","affiliation":[{"name":"Department of Pathology, Transplant Research Centre, Shiraz University of Medical Sciences, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,12,31]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11748-005-0023-9"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chest.2024.06.2778"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.1996.00440150133015"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1010-7940(04)00529-9"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1097\/RLU.0b013e31820aa268"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1378\/chest.08-0607"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2532081199"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1111\/bpa.12125"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.4103\/lungindia.lungindia_197_22"},{"issue":"4","key":"e_1_3_2_11_2","article-title":"Benign intrapulmonary schwannoma with high uptake on fluorodeoxyglucose-18 (FDG-18 PET) presenting as a Pancoast tumor","volume":"15","author":"Chauhan S","year":"2023","unstructured":"Chauhan S, Rahman F, Dhillon GS, Hewapathirana U, Mongalo M, Chung A.
