Zhang**, 70 years old, started coughing and coughing 2 months ago, with occasional anterior chest and back pain, which he did not care about, and then his symptoms worsened and he had a chest CT, which revealed a tumor growing in the left anterior mediastinum in the chest cavity, measuring about 8cm*6cm, and also invading the surrounding fat, chest wall, large blood vessels, heart and lungs. The patient and his family went through many large hospitals in the province, but they were all politely rejected. In an emergency, they found our team, and after careful evaluation, they decided to give the patient surgery on 2015-12-*. The operation was extremely difficult because not only the huge tumor and surrounding fat had to be removed, but also the invasive large blood vessels, pericardium and part of the lung had to be removed. The patient recovered well after the surgery and was discharged on the 11th day.
