title: Extragonadal retroperitoneal embryonal carcinoma successfully treated with chemotherapy.
abstract: A 27-year-old Japanese man visited our hospital for further evaluation of multiple shadows on his chest X-ray. A 6 cm hard mass was palpable in the left lower abdominal region. Histological examination revealed that the lung tumor resected by the video-assisted thoracoscopic surgery was an embryonal carcinoma (EC). He was diagnosed as retroperitoneal EC with multiple lung metastases. He underwent chemotherapy with cisplatin, etoposide, and bleomycin, followed by 3 courses. A curative surgical operation revealed that there were no malignant cells in the lung lesions and primary lesion. This patient responded well to chemotherapy and achieved complete remission by chemotherapy.
