Abstract: Benign clear cell tumor (BCCT) is an extremely rare pulmonary neoplasm. We report herein a case of BCCT of the lung that was diagnosed by a transbronchial lung biopsy (TBLB). The findings of hematoxylineosin and immunohistochemistry obtained by the TBLB were consistent with a diagnosis of BCCT of the lung. Wedge resection was subsequently performed by video-assisted thoracotomy. To the best of our knowledge, this is the first reported case of BCCT diagnosed by TBLB.
