Rhabdomyosarcoma in the mediastinum coexisting with metastatic non-seminomatous germ cell tumor, so-called somatic-type malignancy, is a rare carcinoma and has poor survival. This study reports a case of diffuse and huge hepatic metastasis of non-seminomatous germ cell tumor associated with coexisting embryonal rhabdomyosarcoma in the mediastinum. A 31-year-old man presented with abdominal pain...

Mature teratomas are the most common type of mediastinal germ cell tumors. They typically occur in young adults (15 to 35 years) and 95% of these teratomas occur in the anterior mediastinum. Herein, we report a case of a huge mediastinal teratoma in a 16-year-old boy who presented with a history of chest pain, cough, exertional dyspnea, and fever. Chest X-ray and spiral computed tomography (CT)...
