Surgical resection of a pulmonary pleomorphic carcinoma involving the azygos vein

We report a case of surgical treatment of pulmonary pleomorphic carcinoma invading the azygos vein. Chest computed tomography (CT) revealed a mass of 6 cm in size, in the upper lobe of the right lung. He underwent the right upper lobectomy and lymph node dissection with combined resection of the involved azygos vein. Histological examination revealed pleomorphic carcinoma (pT3N0M0, stage IIB). The postoperative course was uneventful, and he was alive without recurrence 26 months after the operation. Six cases of pleomorphic carcinoma have been surgically treated between June 2008 and August 2009 in our institute. Early diagnose with complete resection is suggested to be essential in the improvement of survival for this disease based on review of our experience.
