A case of adenocarcinoma presenting with cystic lesion and recurrent pneumothoraces

Abstract

Abstract Background In this paper, a rare case is reported, where the patient is a 74-year-old man. He suffered from recurrent pneumothorax within half a year and experienced a relapse after receiving conservative treatments. Case presentation Diagnostic workup revealed a cystic lesion in the right middle lobe, which has been interpreted as a bulla during the initial chest CT scan. Due to recurrent pneumothorax and poor response to the conservative treatments, the patient underwent bullectomy and pleurodesis. The pathology showed that the wall of the cystic lesion was invasive adenocarcinoma. Conclusions This case highlights the importance of monitoring cystic lesions in the lungs, especially in patients with a history of smoking and emphysema.
