ELP is a rare chronic pulmonary disorder characterized by nonspecific clinical symptoms and imaging findings. When manifesting as a mass or nodule, features such as lobulation and spiculation on imaging can closely resemble lung cancer, frequently leading to misdiagnosis and unnecessary surgical intervention. We present a retrospective analysis of a pathologically confirmed case of ELP to improve recognition of this condition among both clinicians and pathologists.<\/jats:p>","DOI":"10.3389\/fmed.2025.1723734","type":"journal-article","created":{"date-parts":[[2026,1,5]],"date-time":"2026-01-05T05:30:06Z","timestamp":1767591006000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Exogenous
