Many techniques have been proposed for surgical training as a learning process for young surgeons or for the simulation of complex procedures. Stereolithograpfy, a rapid prototyping technique, has been presented recently as an option for these purposes. We describe the case of a 12 years old boy, diagnosed with Ewing's sarcoma in the cervical spine. After a surgical simulation accomplished in t...

Objective: Noncoding RNAs are emerging as important players in gene regulation and cardiovascular diseases. Their roles the pathogenesis of atherosclerosis not fully understood. The purpose this study was to determine role played by a previously uncharacterized long noncoding RNA, RP11-728F11.4, development mechanisms which it acts. Approach Results: Expression microarray analysis revealed that...

BACKGROUND AND PURPOSE Chordoma is a relatively rare tumor of the skull base and sacrum thought to originate from embryonic remnants of the notochord. Chordomas arising from the skull base/clivus are typically locally aggressive with lytic bone destruction. When chordomas occur in an extraosseous location, they may mimic other lesions of the nasopharynx. We present 5 cases of primarily extraoss...

Extraosseous Ewings tumor (EES) is a rare entity. Few cases have been reported in literature. There are no specific guidelines for management of this disease. We are reporting a case of EES arising from left lateral abdominal wall. We did wide excision of tumor followed by chemoradiation. Patient is asymptomatic after 8 months of follow up.

A rapidly enlarging right sternoclavicular mass in a young male was labeled as a nonspecific mass. MRI played a crucial role in characterizing the lesion, helping to define the possible mesenchymal origin and the relative involvement of the surrounding structures. We also discuss the differential diagnosis of an extraosseus Ewing sarcoma (ES), with its imaging findings.

Extraosseous Ewing sarcoma is now regarded as a member of the Ewing sarcoma/primitive neuroectodermal tumor (PNET) family. It typically involves the soft tissues of the chest wall, pelvis, paravertebral region, abdominal wall, retroperitoneal region and extremities of children, adolescents and young adults, but it seldom occurs in the female genital tract. We report an extremely rare case of re...

BACKGROUND: The role of high dose therapy (HDT) with autologous stem cell transplantation (AuSCT) for the treatment of bone and soft tissue sarcomas remains investigational. There are few reports examining this strategy focusing on the adult population. METHODS: We retrospectively reviewed our experience of adult patients undergoing HDT and AuSCT for 'paediatric' sarcomas. RESULTS: A total of 1...
