Abstract

<p>A 42-year-old woman who presented with a slow-growing nodular lesion of 10.3 mm in diameter in the left lower lobe of the lung on CT taken for cervical cancer in 2013 was referred to our department in 2021 when the lung lesion increased to 14.8 mm. Although the nodule which had been diagnosed as benign was growing very gradually, the malignant disease including metastatic tumor could not be excluded. Thus, the resection of the tumor was carried out. The lesion was located near the left inferior pulmonary vein enough to indicate the lower lobectomy of the lung. However, by transecting the V10 branch, the lesion was successfully removed by wedge resection with a stapler with a surgical margin of about 5 mm from the inferior pulmonary vein. Intraoperative frozen sectioning disclosed possible pulmonary sclerosing pneumocytoma or adenocarcinoma in situ without any findings of invasiveness. Thus, further extended resection was not carried out by securing 5 mm surgical margin. The postoperative pathological diagnosis defined pulmonary sclerosing pneumocytoma. The patient is well without recurrent disease as of 12 months after the surgery.</p>
