case of schwannoma with hemorrhagic cystic degeneration in the right upper mediastinum was admitted to the Affiliated Hospital of Ningbo University in July 2010. The patient shows symptoms of cough and shortness of breath. He received video-assisted thoracoscopic resection of right upper mediastinal mass. This disease displayed different symptoms depending on tumor size and location.

Desmoplastic small round cell tumor (DSRCT) is rare and a recently described, poorly differentiated malignant tumor and it usually presents with widespread intra-abdominal involvement. We report a case of DSRCT arising form the mediastinum which was treated with multimodality anticancer therapy in 15 year-old girl.

Atretic encephaloceles or myelomeningoceles are frequently solid due to hamartomatous proliferation of fibrous tissue and blood vessels. Because of the fibrous nature of the tumor with no cystic cavity and unusual location with no connection to CNS, they are frequently regarded as insignificant hamartomas. Apart from this terminology, they are also described as cutaneous meningiomas or hamartomas with ectopic meningothelial elements by the presence of meningothelial cells. We report a case of atretic encephalocele in the parietal scalp of an 8 year-old boy and a case of myelomeningocele in the posterior mediastinum of a 31 year-old woman. The terms atretic encephalocele and myelomeningocele are more appropriate for these cases because they include their pathogenesis and the non-neoplastic nature of the lesion.

Malignant transformation of teratoma in the anterior mediastinum is rare; the mass usually has a long history and is seen in older patients. We report a case of teratoma with malignant transformation in the anterior mediastinum, complicated by rupture. CT revealed a lobulated, inhomogeneous cystic mass with a fat com-ponent and wall calcifications. The lateral wall was disrupted and consolidation in the adjacent left upper lobe was noted, suggesting rupture. A heterogeneously enhanced solid portion, obliterating the fat plane between the mass and the great vessels was present in the medial aspect of the mass, and pathologic examina-tion demonstrated the presence of adenocarcinoma.

Neurogenic tumors located in the posterior mediastinum, generally require surgery which be confronted with greater risk,therefore, to design the best surgical approach and surgical methods is essential. A 67-year-old female patient had pharyngeal foreign body sensation and dysphagia. Thyroid ultrasound showed the right thyroid had a little nodule, and the left thyroid had a hypoechoic lumps. Neck enhanced CT showd mediastinal mass, esophageal tumor origin or stromal tumor? We used the jugular approach to resect the tumor which eventually diagnosed as schwannoma. The meditational benign tumor with an envelope easy to peel can employ the jugular approach to resect it completely.
