[Complete Resection of Non-seminomatous Germ Cell Tumor with Plastron Approach]

A 17-year-old man was admitted to our hospital for the abnormal chest shadow. Chest computed tomography(CT) demonstrated mediastinal tumor, measuring 13 cm in diameter with high serum level of alpha fetoprotein (AFP) and human chorionic gonadotropin (hCG). The lesions were diagnosed as mixed germ cell tumors including a non-seminomatous malignant component by CT guided needle biopsy. After 5 courses of chemotherapy, the serum AFP and hCG were decreased almost normal level but the tumor size was not changed. Because it seemed to be difficult to get sufficient operating field with standard median sternotomy and patient wanted to treat funnel chest, we selected tumor resection with plastron approach. The tumor was completely resected with a good operation field by this procedure.
