A case of "benign clear cell tumor of the lung" occurred in an 8-year-old girl. The tumor was a solid well-circumscribed mass, measuring 1 cm in diameter. Histologically, it consisted of polygonal cells intermingled with large, thin-walled vessels. Glycogen was scarce in paraffin sections; however, electron microscopic observation revealed a large amount of glycogen. Intracytoplasmic filaments were not observed, but scattered pinocytotic vesicles and plaquelike densities along the plasma membrane were found.
