[Surgically Treated Clear Cell Carcinoma of the Lung; Report of a Case].

We report an operative case of primary clear cell carcinoma of the lung. A 47-year-old man consulted our hospital because of back pain and an abnormal shadow on a chest computed tomography(CT). A chest CT revealed a nodule in the lung cyst. A diagnosis of lung cancer was suspected and the patient underwent right upper lobectomy with standard nodal dissection. Pathological findings are the lung cancer spreading along the cysts' inner walls. Most of the tumor cells were characterized as having large clear cytoplasm. Screening of the abdomen performed pre- and post-operatively revealed no suspected primary lesion in the kidney, and the tumor was diagnosed as clear cell carcinoma of the lung. Postoperative adjuvant chemotherapy with cisplatin and vinorelbine ditartrate was performed. Patient is well without reccurence 3 years after surgery.
