The advance of the immunobiology clarifies the nature of non-Hodgkin's lymphoma(NHL). In addition the proceed in the immunophenotyping renders the classification of NHL. According to the Revised European American Lymphoma(REAL) classification, classified by the etiologic factors, molecular biological characteristics, immunophenotype, cytogenetics and histologic feature, nasal T/NK-cell lymphoma(=angiocentric lymphoma) belongs to the category of peripheral T-cell and natural killer cell lymphoma. Nasal T/NK-cell lymphoma is a distinct clinicopathologic entity characterized by progressive necrotic lesions in the nasal cavity, nasopharynx, and palate. The cellular origin of this tumor has been controversial. Although most nasal T/NK-cell lymphomas are of NK-cell lineage, being CD56+, negative for surface CD3(Leu4), and unassociated with rearrangements of the T-cell receptor genes, other minor variants have been reported. This lymphoma is a rare disease and usually experienced in adult. Recently, we experienced a rare type lymphoma, nasal T/NK-cell lymphoma, in 14 years old boy. His soft mass occupied the right nasal cavity including the nasal septum and turbinate. Pathologically this nasal mass showed the infiltration into the vascular wall, illustrating angiodestructive lesion. The cellular origin was NK-cell lineage, being CD56+ and negative to CD3. Now, we report the case with a brief review of related literatures.

In this report, we present a case of a radiotherapy-induced tracheoesophageal fistula treated with the fluoroscopy-guided insertion of a covered stent through the gastrostomy route using both the antegrade and retrograde approaches. The initial antegrade endoscopic and fluoroscopic stent insertion procedure failed due to severe esophageal stricture. Compared to the endoscopic approaches, fluoroscopy-guided radiologic procedures are generally less invasive and more successful because they allow for a better understanding of the anatomy outside the lumen during the procedure and enable the use of devices with smaller diameters.

Purpose: Trauma is one of the major cause of death in Korea. This study focused on the survival rate and the neurologic outcome for patients with traumatic cardiac arrest (CA) at one emergency center. Methods: We retrospectively reviewed the medical records of patients with traumatic CA who were seen at a regional emergency medical center from January 2010 to December 2011. From among major trauma patients at that medical center, adults older than 18 years of age who had CA were included in this study. CA included out-of-hospital CA with arrival at the Emergency Department (ED) within three hours and in-hospital CA. We checked the survival rate and the neurologic outcome. Results: A total of 61 patients were analyzed: 32 patients had return of spontaneous circulation (ROSC), 6 patients survived to discharge (survival rate: 9.84%), and 4 were still alive 90 days after discharge. The Cerebral performance category (CPC) scores at 6 months after discharge showed 1 good and 5 poor in neurologic outcomes. Factors such as initial rhythm of CA, part with major injury, Revised Trauma Score (RTS) and pH, were significant for ROSC, survival, and neurologic outcome in patients with traumatic CA. Conclusion: In this study, patients who had traumatic CA showed a 9.84% survival rate and a 1.64% good neurologic outcome. The results are poorer than those for CA caused by disease. Multi-center, prospective studies are needed.
