Two typical cases of epithelioid sarcoma were examined by immunohistochemical stain using antibodies to epithelial membrane antigen, carcinoembryonic antigen, vimentin and cytokeratin. Both cases showed positive reactivity for the four kinds of antibodies. These results point to the fact that epithelioid sarcoma simultaneously expresses epithelial markers and characteristic mesenchymal phenotypes. Epithelioid sarcoma appears to be a tumor derived from a multipotential mesenchymal cell with multidirectional differentiation.

Bilateral nonfunctioning adrenal cortical carcinoma is an extremely rare disease with poor prognosis. We report a case of asynchronous bilateral nonfunctioning adrenal cotical carcinoma. The patient was a 55 year-old man who had complained of discomfort in the right upper quadrant and flank area. There was no endocrinological abnomaliries. Abdominal CT revealed about 9.5 x 7.0 cm sized right adrenal mass. Under the impression of nonfunctioning adrenal cortical carcinorna, right radical adrenalectomy was performed. After 1 year from operation, 5.0 x 7.0 x 6.0 cm sized new mass was detected in the left adrenal gland with metastasis to the peritoneum.

Malposition of the extracorporeal membrane oxygenation (ECMO) venous cannula in the azygos vein is not frequently reported. We hereby present such a case, which occurred in a neonate with right-sided congenital diaphragmatic hernia. Despite ECMO application, neither adequate flow nor sufficient oxygenation was achieved. On the cross-table lateral chest radiograph, the cannula tip was identified posterior to the heart silhouette, which implied malposition of the cannula in the azygos vein. After repositioning the cannula, the target flow and oxygenation were successfully achieved. When sufficient venous flow is not achieved, as in our case, clinicians should be alerted so they can identify the cannula tip location on lateral chest radiograph and confirm whether malposition in the azygos vein is the cause of the ineffective ECMO.

BACKGROUND: Understanding the differentiation and migrating character of the tympanic membrane, external auditory canal as well as cholesteatoma pathogenesis needs knowledge about epithelial generation center. OBJECTIVE: We investigated the distribution of the epithelial generation center in the tympanic membrane and external auditory canal using 5-bromo-2-deoxyuridine(BrdU) immunohistochemistry. MATERIALS AND METHODS: BrdU was injected into peritoneum of 10 Mongolian gerbils and gerbil's temporal bones were obtained and serial section was done. Anti-BrdU antibody immunohistochemical stain was done. RESULTS: The labeling index was highest at posterosuperior quadrant of pars tensa, higher at malleus handle attached area and annulus region. On pars flaccida, labeling index was high at entire area. The labeling index of deep meatal skin was higher than that of lateral meatal skin, especially near annulus area. According to results, epithelial generation centers are thought to be on pars flaccida, posterosuperior quadrant of pars tensa, malleus handle attached area and annulus region. CONCLUSION: These findings are similar to those of human tympanic membrane and external auditory canal, and gerbils can be used as a animal model for study of normal human tymapnic membrane, external auditory canal and cholesteatomas.

Spinal fusion has performed for instability and anatomical reconstruction since 1985 by Barthe. Bone grafts and synthetic materials has been used for spinal fusion, but they have several limitations and complications. Recently a new synthetic polymer B.O.P.(Biocompatible Osteoconductive Polymer) was developed and it overcome the limitations of other materials. The B.O.P. showed no foreign body reaction and gave scaffolding for the osteoconduction and osteointegration. Authors operated 35 cases of spinal fusion with B.O.P. and the results and literature reviews were discussed.
