Abstract
We report a rare case of cavernous hemangioma of the lung. A 36-year-old woman was admitted to our hospital for an abnormal shadow on chest roentgenogram. She had no symptoms. Chest roentgenogram showed a small nodular shadow in the left lower lung field. Computed tomogram of the chest demonstrated a nodular shadow in contact with the chest wall at the lingula. Pulmonary arteriogram showed no abnormal findings. Operation was performed with thoracoscopic techniques. An elastic soft mass was found in the lingula. It bulged under the visceral pleura. The tumor was round and had no definite capsules. Microscopic examination revealed a cavernous hemangiomatous pattern. Most cells lining the lumens of the cavernous structure stained positively for anti-CD 34 antigen.
