Pulmonary metastases typically appear as solid nodules, whereas cavitary pulmonary metastases are exceptionally rare and may closely mimic infectious lung disease. Case Presentation: Herein, we report the case of a woman diagnosed with epithelioid sarcoma of the foot at 26 years of age. She developed slowly progressive cavitary pulmonary lesions more than a decade after initial treatment. During long-term follow-up without adjuvant therapy, small pulmonary nodules gradually evolved into cavitary lesions, raising strong suspicion for tuberculosis or fungal infection rather than metastatic disease. Video-assisted thoracic surgery was performed for definitive diagnosis and treatment, and histopathological examination confirmed metastatic epithelioid sarcoma. Conclusion: This case underscores the fact that epithelioid sarcoma can present as a chronic cavitary pulmonary disease that mimics infection. Clinicians should consider metastatic disease in the differential diagnoses of cavitary lung lesions in patients with a history of this malignancy.<\/jats:p>","DOI":"10.1159\/000552335","type":"journal-article","created":{"date-parts":[[2026,6,2]],"date-time":"2026-06-02T16:00:51Z","timestamp":1780416051000},"page":"978-983","source":"Crossref","is-referenced-by-count":0,"title":["Chronic Cavitary Pulmonary Metastases Mimicking Infection in Epithelioid Sarcoma: A Case Report"],"prefix":"10.1159","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0802-8553","authenticated-orcid":false,"given":"Yudai","family":"Murayama","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Makoto","family":"Abe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hirokazu","family":"Ideta","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rumi","family":"Nakagawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koichi","family":"Inoue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-2594-6162","authenticated-orcid":false,"given":"Eisuke","family":"Miura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaoru","family":"Hirabayashi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takehiko","family":"Yamaguchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroyuki","family":"Kawashima","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazutaka","family":"Kikuta","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2026,6,2]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1378\/chest.116.1.263"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/s0003-4975(02)05018-x"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1843.2006.00925.x"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1097\/jto.0b013e31816e23e6"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1684\/ejd.2011.1257"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.12968\/hmed.2012.73.2.110"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.3904\/kjim.2016.31.1.191"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.3892\/ol.2018.7868"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.arbr.2021.03.004"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejso.2020.03.215"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.21.2.g01mr17403"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016\/j.chest.2018.02.026"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.4102\/sajr.v23i1.1663"}],"container-title":["Case Reports in Oncology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000552335","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,24]],"date-time":"2026-07-24T16:01:51Z","timestamp":1784908911000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000552335"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,6,2]]},"references-count":13,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2026,1,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000552335","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.32542269","asserted-by":"subject"}]},"ISSN":["1662-6575"],"issn-type":[{"value":"1662-6575","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,6,2]]}}}
