We present here in the case of a patient who underwent resection of clear cell carcinoma of the lung, a rare histological type. A screening test of the 71-yearold woman revealed a 2.0-cm lesion in S4 of the right lung with a diagnosis of bronchioloalveolar carcinoma before resection. Under the guidance of video-assisted thoracoscopy, right middle lobe resection and mediastinal lymph node dissection were performed. The histopathological examination showed clear, slightly acidophilic tumor cells rich in fine granular components proliferating in an alveolar fashion. Immunostaining was diagnostically useful, distinguishing clear cell carcinoma from lung metastasis of renal clear cell carcinoma or clear cell squamous cell carcinoma.
