Multifocal PIT, where multiple isolated PIT origins coexist in the lungs, has only been confirmed in one previous case report, in which the patient died before surgical resection. These tumours are difficult to diagnose as imaging findings are non-specific, and non-invasive biopsy often yields inaccurate results. We present the case of a man in his 70s who was referred to thoracic surgery for resection of a presumptive endobronchial pulmonary carcinoid tumour. Only after surgical resection did we identify that the patient had multifocal PIT. In this report, we describe our diagnostic and management process for this patient and review the current literature on PIT.<\/jats:p>","DOI":"10.1136\/bcr-2023-257789","type":"journal-article","created":{"date-parts":[[2023,11,24]],"date-time":"2023-11-24T12:30:49Z","timestamp":1700829049000},"page":"e257789","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Multifocal primary intrapulmonary thymoma successfully resected via robotic-assisted thoracoscopic surgery"],"prefix":"10.1136","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3023-1892","authenticated-orcid":false,"given":"Daniel","family":"Shell","sequence":"first","affiliation":[{"name":"Cardiothoracic Surgery, Barwon Health, Geelong, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James","family":"Malone","sequence":"additional","affiliation":[{"name":"Respiratory Medicine, Barwon Health, Geelong, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jane","family":"Kho","sequence":"additional","affiliation":[{"name":"Anatomical Pathology, Melbourne Pathology, Collingwood, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cheng-Hon","family":"Yap","sequence":"additional","affiliation":[{"name":"Cardiothoracic Surgery, Barwon Health, Geelong, Victoria, Australia"},{"name":"School of Medicine, Deakin University Faculty of Health, Geelong, Victoria, Australia"},{"name":"Epidemiology and Preventive Medicine, Monash University, Melbourne, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2023,11,24]]},"reference":[{"key":"2025082703550185000_16.11.e257789.1","doi-asserted-by":"publisher","DOI":"10.1136\/thx.40.6.471"},{"key":"2025082703550185000_16.11.e257789.2","doi-asserted-by":"crossref","first-page":"7531","DOI":"10.21037\/jtd-2019-thym-02","article-title":"Epidemiology of thymoma","volume":"12","author":"Rich","year":"2020","journal-title":"J Thorac Dis"},{"key":"2025082703550185000_16.11.e257789.3","doi-asserted-by":"crossref","first-page":"245","DOI":"10.1007\/s00428-016-1967-0","article-title":"The spectrum of ectopic thymomas","volume":"469","author":"Weissferdt","year":"2016","journal-title":"Virchows Arch"},{"key":"2025082703550185000_16.11.e257789.4","first-page":"345","article-title":"Primary intrapulmonary neoplasm (thymoma?) associated with myasthenia gravis: report of case","volume":"26","author":"McBurney","year":"1951","journal-title":"Proc Staff Meet Mayo Clin"},{"key":"2025082703550185000_16.11.e257789.5","first-page":"101423","article-title":"Multifocal primary intrapulmonary thymoma: a rare subtype of ectopic thymoma","volume":"33","author":"Lourdesamy Anthony","year":"2021","journal-title":"Respir Med Case Rep"},{"key":"2025082703550185000_16.11.e257789.6","doi-asserted-by":"crossref","first-page":"304","DOI":"10.1097\/00000478-199503000-00008","article-title":"Primary intrapulmonary thymoma.
