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.

5.Atretic encephalocele/myelocele: case reports with emphasis on pathogenesis.

Journal of Korean Medical Science 1996;11(4):364-368
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.

The present study was to develop and design a new sonography rigid bronchoscopy and corollary vacuum-assisted biopsy device system with less injury and complication. The system combined ultrasonic-probe with ultrasound catheter, a new medical ultrasound technique, and rigid bronchoscopy (RB) which is improved with an auxiliary vacuum-assisted biopsy device. The principle of the device is vacuum suction and rotary knife. The reduced outer diameter of the RB led to less pain and lower complications for the patient. With the help of ultrasonic-probe (30 MHz), lesions and blood vessels can be identified clearly and unintentional puncture and damage to blood vessels can be avoided. Plenty of lesions can be obtained quickly through the vacuum-assisted biopsy device without getting puncture needle in and out repeatedly. The novel endobronchial sonography rigid bronchoscopy and matched vacuum-assisted biopsy device has many remarkable advantages. It can enlarge the applied range of the RB from endobronchial to mediastinal lesions, avoiding unintentional puncture of vessels. Obtaining multiple samples with a higher accuracy rate than that by other sampling techniques, minimizing operation time, alleviating pain and decreasing the complication rate, the system makes up the technical deficiency for the diagnosis and treatment of the mediastinal lesions, to a certain degree.

Classical angiomyolipomas are benign tumors composed of various tissues, including fat, abnormal blood vessels and smooth muscle cells. The present study reports a male patient affected by mediastinal angiomyolipomas with massive chylous pleural effusion. The tumors were characterized with histological and immunohistochemical methods.
