We experienced a case of benign clear cell tumor of the lung. It is a rare and most unusual pulmonary neoplasm. Only 40 cases have been reported in the foreign literatures and 16 cases in the Japanese literatures. A 30-year-old man, who revealed a coin lesion in the chest roentogenogram at the health screening, underwent resection of the right lower lobe. Microscopically, the tumor cells are similar to clear cell carcinoma of the kidney and have glycogen in the cytoplasm. Ultrastructually, fibrous banded collagen structures were found in the intercellular space. These findings suggest possibility of neural tissue origin of the clear cells.
