A 68-year-old woman, who was scheduled to undergo operation for bilateral gonarthritis under general anesthesia in September 1998, was detected having an about 1.5cm circular shadow in the right lower lung field on a chest simple x-ray film taken preoperatively. She was admitted to the hospital for close examination and treatment, when no particular abnormalities in physical and blood biochemical data were observed. Chest CT scan revealed a demarcated tumor shadow with homogeneous center in the right S8, but no pleuralimpaction nor lymph nodes swelling was presented. Bronchoscopy revealed no anomalies. Since a possibility of malignant tumor could not be still ruled out, a thoracoscopy-aided partial pneumonectomy was performed for the purpose of examination and treatment. Pathological diagnosis was sclerosing hemangioma of the lung. Sclerosing hemangioma of the lung which commonly occurs in the pulmonary peripheries is a relatively rare benign tumor. We often have great difficulty in preoperative diagnosis of the disease, even by intraoperative frozen section diagnosis. For such cases, this thoracoscopic operation that is minimal invasive can be recommended to treat and also to make the definite diagnosis of the disease.
