Abstract:
Background and objective Lung cancer presenting as cystic lesions was ifrst described by Anderson and Pierce in 1954. Lung cancer presenting as cysts is a rare entity in clinical practice. Differential diagnosis is diffcult in the benign-like cyst. hTis study investigated the clinical characteristics, diagnosis and treatment of lung cancer presenting as cysts. Methods We conducted a retrospective analysis of the clinical records of 24 patients who underwent surgery for a primary lung cancer presenting as cysts in our department between 2007 and 2013. We deifned a‘hTin-walled cyst’ as a cavitary lesion with a wall thickness of 4 mm or less along at least 75%of the circumference of the lesion. hTe whole group underwent post-operative follow-up. Results hTe incidence of cystic lung cancer was 0.49%(24/4,897) of surgical cases. hTe subjects’ age ranged from 19 to 77 yr with a median age of 56.5 yr. Ten cases presented with respiratory symptoms while 14 showed abnormal shadows on a chest CT without symptoms. Histological analysis showed that 18 cases were of adenocarcinoma, three of squamous cell carcinoma, one of small cell carcinoma, one of adenosquamous carcinoma and one of large cell carcinoma. hTree patients were dead, and the remaining 21 patients are alive and disease free at the end of follow-up. Conclusion Cystic lung cancer should be kept in mind during the differential diagnosis of focal benign cyst. Cystic lung cancer could achieve a good outcome if early diagnose can be obtained.
