Here, we report a case of effective thoracoscopic lung reduction for P-EMC. A woman in her 80s was referred to our hospital following detection of an abnormal shadow on a chest CT performed during an annual lung cancer screening programme. The mass was 11 mm in the right lower lobe, and 11 mm and 5 mm multiple nodules were identified in the left lower lobe. A thoracoscopic partial right lung resection was performed for diagnosis and treatment, and the patient was diagnosed with P-EMC. After a follow-up of approximately 2 years, a left basal segmentectomy and lymph node dissection by complete video-assisted thoracoscopic surgery were performed. The final pathology revealed a P-EMC.<\/jats:p>","DOI":"10.1136\/bcr-2025-269329","type":"journal-article","created":{"date-parts":[[2025,12,30]],"date-time":"2025-12-30T18:05:24Z","timestamp":1767117924000},"page":"e269329","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Triple primary pulmonary epithelial-myoepithelial carcinoma"],"prefix":"10.1136","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7620-4921","authenticated-orcid":false,"given":"Masakazu","family":"Kimura","sequence":"first","affiliation":[{"name":"Department of Thoracic Surgery, Niizashiki Central General Hospital, Niiza, Saitama Prefecture, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kuniharu","family":"Miyajima","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, Niizashiki Central General Hospital, Niiza, Saitama Prefecture, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kana","family":"Kitahara","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, Niizashiki Central General Hospital, Niiza, Saitama Prefecture, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takafumi","family":"Kono","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, Niizashiki Central General Hospital, Niiza, Saitama Prefecture, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,12,30]]},"reference":[{"key":"2025123016250683000_18.12.e269329.1","unstructured":"Seethala R , Bell D , Fonseca I , et al .
