“…Although percutaneous or transbronchial aspiration cytology has been reported to be useful, 3 the risk of infection by puncture, especially in areas that are difficult to puncture due to respiratory movement, must be considered. In rare cases, bronchogenic cysts have been reported to become malignant, 4 and as with mediastinal tumours (e.g., thymic epithelial tumours), biopsy should not be performed if it is judged to be resectable. Bronchogenic cysts are classified into intrapulmonary and mediastinal types, most of which are asymptomatic, but intrapulmonary types sometimes have communication with the bronchi and may be symptomatic.…”

Bronchogenic cysts that occur within the diaphragm are rare and difficult to diagnose preoperatively. We experienced the case of a patient with an abnormally high serum carbohydrate antigen 19‐9 (CA19‐9) level before surgery. The diagnosis of intradiaphragmatic bronchogenic cyst was made at the time of surgery. The patient was a 50‐year‐old woman with upper abdominal pain with an incidentally elevated serum CA19‐9. Although the tumour location could not be established on images, a tumour within the diaphragm was confirmed during the operation. The diaphragm was incised and the tumour was removed together with the capsule. Bronchial cysts were diagnosed histopathologically, and immunohistochemical examination revealed that the bronchial epithelial cells were positive for CA19‐9. When managing patients with bronchogenic cysts in the diaphragm, it is difficult to make a preoperative diagnosis or determine the location of the tumour; thus, careful planning is required before surgery.

━━ Background. Bronchogenic cysts are commonly found in the mediastinum but also occasionally in the lung parenchyma. We herein report a rare case of lung cancer arising in an intrapulmonary bronchogenic cyst. Case. A 58-year-old woman with a smoking history developed a cough and hemosputum in April 2021. On an examination at a local hospital, no abnormal shadow was found on her chest radiograph, but computed tomography of the chest revealed a 6.4-cm pulmonary cyst with irregular wall thickness in the right lower lobe. Fluorodeoxyglucose-positron emission tomography showed abnormal accumulation in the thickened wall of the pulmonary cyst (maximum standardized uptake value: 4.22). The diagnosis based on sputum cytology was class IIIA, but lung cancer with cystic lesion could not be excluded. In September 2021, the patient underwent resection of the cystic lesion under thoracoscopic surgery. A frozen section obtained during surgery revealed adenocarcinoma, and video-assisted thoracoscopic right lower lobectomy was performed. Microscopic findings showed bronchogenic lung cysts and the proliferation of malignant cells along the cystʼ inner walls (pT3N0M0). The patient was alive nine months after surgery without recurrence. Conclusion. Only 10 cases of lung cancer arising from intrapulmonary bronchogenic cyst have been reported in Japan. When carcinoma is suspected in the bronchogenic cyst, appropriate surgical procedures should be considered.
