Superior vena cava syndrome occurs when the superior vena cava and subsequent collateral veins of the thorax, neck, and head are obstructed, most commonly by a malignant neoplasm such as lung cancer. We discuss a case due to seminoma. A 31-year-old man referred for further recurrent facial and neck swelling examination, was found in chest radiography to have an abnormal shadow and shown in computed tomography (CT) scan to be a large mass of the anterior mediastinum diagnosed by aspiration cytology as seminoma. After radiotherapy, the tumor shrank markedly and neck swelling disappeared. The man underwent chemotherapy for maintenance after radiotherapy. Although commonly encountered by pulmonary physicians and surgeons superior vena cava syndrome is rarely seen by otolaryngologists who should consider this disease in subjects reporting afebrile, painless cervical swelling.
