“…A previous report suggested that traction ectasia of the conducting airway caused by fibrosis was one of the mechanisms of formation of thin-walled cavitary lung cancer [2], indicating that the actual thin-walled cavity is formed because of tumor-related collapsed fibrosis. In our study, approximately 17% of cases exhibited combined type cavity linings; similar cases of cavitary adenocarcinoma with internal cavity surfaces being lined with dilated bronchial and adenocarcinoma cells have been reported [5,17]. These results suggest that a combination of tumor destruction and bronchial dilation due to tumor-related collapsed fibrosis may be one of the causes of cavity formation.…”

Ciliated muconodular papillary tumor (CMPT) of the lung is a newly defined and extremely rare tumor characterized by a papillary growth pattern, consisting of ciliated columnar cells, mucous cells, and basal cells with abundant mucin production. Tumor definitions and clinicopathological features continue to be debated. Herein, we report five surgical cases of CMPT to characterize its radiographic, gross, and microscopic features. The five cases involved three male patients aged 80, 67, and 66 years, and two female patients aged 73 and 70 years. Three cases were discovered during health care screenings, and two cases were found during follow-up for another synchronous cancer. Histopathological examination revealed that the tumor tissue was composed of ciliated columnar cells, mucous cells, and basal cells with abundant mucin production. Neither nuclear atypia nor mitotic figures were observed. All patients had good prognoses. The benign histological features and clinical courses in these five cases suggest that CMPT is an independent and benign tumor of the lung.

Primary lung cancer manifesting as a thin-walled solitary cavity, occurs relatively infrequently. The most common histologic type presenting such a pattern is squamous cell cancer, followed by adenocarcinoma, and finally-large cell cancer. Cavitation is typically not seen in small cell lung cancer. Entities indicating malignancy of such lesions include irregular cystic wall, wall nodule formation, nodular septa or increased standard uptake on positron emission tomography (PET). We are presenting a case of a squamous cell lung cancer manifesting on chest CT as a thin-walled septated cavity with irregular margins mimicking a cyst. The lesion was reported unchanged in a follow-up computed tomography after 3 months. A follow-up scan obtained 2 years after initial examination showed thickening of a cyst wall, solid structures within its lumen and thoracic lymph nodes enlargement.
