Nearly all cancers arising in association with cystic airspaces are non\u2010small cell lung cancers, whereas cases of small cell lung cancer (SCLC) in this setting are rarely reported. A 72\u2010year\u2010old woman with a history of smoking was referred to our hospital for evaluation of an abnormal chest shadow. Computed tomography (CT) revealed a cystic airspace in the left upper lobe, along with a nodular lesion adherent to the cyst wall with polypoid extension into the lumen. Marked uptake of 18F\u2010fluorodeoxyglucose was observed in the nodular lesion on positron emission tomography\u2013CT. Consequently, primary lung cancer was suspected, and surgical resection was performed. Histopathological examination of the resected specimen led to a diagnosis of SCLC. Although rare, SCLC could arise from cystic airspaces. Nodules abutting cystic airspaces, as well as cyst wall thickening, warrant close short\u2010term follow\u2010up.<\/jats:p>","DOI":"10.1002\/rcr2.70709","type":"journal-article","created":{"date-parts":[[2026,8,3]],"date-time":"2026-08-03T05:19:00Z","timestamp":1785734340000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Small
