Cases have been reported of a large teratoma of the anterior mediastinum extending to the neck, causing symptoms such as dyspnea, which can be quickly detected by Ultrasound, and patients can be quickly treated. In adults, primary teratoma at the suprasternal foss that not accumulate thyroid gland upward and not invade the mediastinum are rare, usually have no obvious clinical symptoms and are found in most patients by chance. In this literature, we report a rare case of mature cystic teratoma in the suprasternal fossa of a 33-year-old male. Preoperative ultrasonography showed a superior sternal fossa tumor with less calcification and more adipose tissue. The final pathologic diagnosis was mature cystic teratoma through open surgery of the suprasternal neck incision. The patient was followed up for 9 months and there was no recurrence. We believe that the suprasternal notch approach is a safe and effective method for the treatment of mature teratoma without protruding into the superior mediastinum.展开更多
