title: [Multiple Pulmonary Sclerosing Pneumocytoma with Abnormal Accumulation of Fluorodeoxyglucose-positron Emission Tomography Diagnosed by Surgical Treatment;Report of a Case].
abstract: A 36-year-old Chinese woman was referred to our hospital for further examination of an abnormal shadow on chest X-ray. Chest computed tomography(CT) revealed a 5 mm circular nodule in diameter in right lung S3 and a 32 mm mass in diameter in right lung S7. The S7 mass showed an abnormal accumulation of SUVmax=4.0 on positron emission tomography( PET)-CT. Transbronchial biopsy was performed, but failed to rule out possible malignancy. Differential diagnoses were multiple lung benign tumor, multiple lung metastases from unknown primary cancer, malignant lymphoma or primary lung cancer, and so on. We performed surgical resection for diagnosis. She underwent lung partial resection of S3 at 1st, and the intraoperative diagnosis of carcinosarcoma was made. Therefore, we performed additional lobectomy of the right lower lobe and mediastinum lymph node dissection. The postoperative course was uneventful. Pathological diagnosis was both pulmonary sclerosing pneumocytoma. No findings of recurrence have been detected at 1-year postoperatively.
