Abstract:
Objective:To investigate the clinical characteristics and surgical management based on the clinical manifestation, pathological feature and the medical imaging finding of ciliated muconodular papillary tumor (CMPT).Methods:The data of clinical manifestation, pathological feature and the medical imaging finding of 15 patients with CMPT who received surgical treatment from January 2017 to April 2019 were collected and retrospectively analyzed.Results:CMPT generally occurred in the elderly people. Most of the diameter of the tumor was less than 1 cm, while the diameters of other 3 patient were 1~2 cm. The computed tomography (CT) scan of 9 patients displayed solid nodule, while 4 displayed ground glass opacity (GGO), and other 2 showed no significant abnormal. Thirteen patients received minimally invasive video-assisted thoracoscopic surgery (VATS), the other 2 received open surgery. Eight patients received lobectomy, 3 received thoracoscopic anatomical partial-lobectomy, 4 received wedge resection. The frozen section diagnostic results of 8 patients were adenocarcinoma, including 3 mucinous adenocarcinoma. Other 5 patients were diagnosed as CMPT and 2 were reported as infection nodule. During the perioperative period, 2 patients occurred cardiac arrhythmia, 1 occurred pulmonary infection. None of the patients had local recurrence or distant metastasis during the follow-up.Conclusions:CMPT usually presents as solitary peripheral lung nodules without obvious symptoms. Most CMPTs are incidentally detected by routine CT scan. Some of the cases are accompanied by primary lung cancer probably. Surgical treatment is the major therapy for CMPT. The imaging feature of CT scam usually shows a solid nodule or a GGO locates in peripheral pulmonary. Frozen section diagnosis for CMPTs can be easily confused with adenocarcinoma or mucinous adenocarcinoma.
