A 62-year-old male was admitted for evaluation of a mass shadow on chest film. Chest PA showed 7×5cm lobulated homogenous mass in right upper medial area of lung. On chest computed tomography, there was a Barge irregularly lobulated mass with central necrotic low density area in apical segment of right upper lobe. Right upper lobectomy of the lung was performed. Partial adhesion to parietal pleura of posterior mediastinum and severe adhesion to right upper apicoposterior segment was found during the operation Microscopic and ultrastructural studies(including immunocytochemical stains) of the mass revealed malignant fibrous histiocytoma.

PURPOSE: In the case of serious respiratory distress syndrome (RDS) or relapse of clinical appearances after single treatment, we obtained more effective results with multiple-dose surfactant replacement therapy. We carried out this investigation for comparing and observing clinical progress between single-dose (group S) and multiple-dose (group M) pulmonary surfactant treatment group of neonatal RDS. METHODS: We investigated 48 neonates who were diagnosed as RDS and treated with pulmonary surfactant (PS) replacement therapy in NICU of Kyunghee University hospital from January 2002 to March 2004, then we compared and verified clinical progress of 32 neonates in group S with that of 16 neonates in group M. RESULTS: There were no significant statistical differences in average birth weights, average gestational periods, initial pH values of birth, whether operation of resuscitation at that time of birth was made or not, whether prenatal steroid prescription for mother, RDS classification standardized by Bomsel, and ventilation index (VI) before instillation of PS of two groups. However, there was significant statistical difference in a/A PO2 (P< 0.05). We could observe changes of VI and a/A PO2 within 72 hours have been continuously improved at group S rather than group M. In spite of relapses, group M changed for the better after second dose. There were also no significant differences between the two groups in duration of ventilator therapy, mortality within 28 days after birth, intraventricular hemorrhage by complication, retinopathy of premature, necrotizing enterocolitis, chronic lung diseases, sepsis, and DIC. CONCLUSION: In these relapse cases, as there were no significant differences in the mortality rate and the occurence of complication between group S and group M, the requirement of multiple-dose PS replacement therapy which brought improvement of prognosis was emphasized.

Splenic metastasis from solid cancer is a rare clinical event. Especially splenic metastasis from the lung is very rare. Most spleen metastases are found at autopsy and are part of a widely spread disease. Solitary splenic metastasis in the abscence of other metastases is extremely rare. The authors report the case of a 54-year-old man in whom the only discover distant metastasis from lung cancer was a splenic mass. The splenic lesion was detected after the resection of the primary lung lesion. The time from diagnosis to the development of splenic metastasis was 25 months. The rarity of a solitary spleen metastasis from lung cancer and the treatment modalities are discussed. When solitary spleen metastasis is suspected in a clinical setting, aggressive treatment is indicated, a splenectomy followed by combined modality treatment to prevent the spread and aggravation of the disease.

The synovium is lined by a layer of intimal cells which have been classified on ultrastructural criteria into type A and B synoviocytes. The functionally important lining cells of the synovium(type A and B synoviocytes) are the subjects of many study but have presented problems with their characterization and microscopical identification. Synovial sarcoma is a distinct and generally recognized soft tissue tumor that its origin still raises controversy. In this study, 12 cases of nonspecifically proliferative and resting human synoviocytes have been obtained from the synovium of knee and hip joints, and 3 cases of synovial sarcoma which have arisen in the left thigh, left buttock and right inguinal region were examined with light microscopy, immunohistochemical observation, and electron microscopy. In light microscopic level, it was difficult to differentiate the type A synoviocytes from type B synoviocytes morphologically. The reactive type B synoviocytes were positive for the protein of cytoskeleton such as pancytokeratin, CK1, CK8, CEA, and vimentin. The resting type B synoviocytes showed positive reactions for pancytokeratin, CK1, and CK8. The markers for the monocytes/histiocytes(CD15, CD68, lysozyme, Al-AT, Al-ACT) were reactive in resting and reactive type A synoviocytes. Also, MHC class II antigen was reactive in type A synoviocytes. Three cases of primary synovial sarcoma were 2 fibrous monophasic and 1 biphasic. Spindle-shaped cell in fibrous monophasic synovial sarcoma showed reactivity for CK7 and pancytokeratin, and epithelial cells (lining the glands) in biphasic synovial sarcoma were reactive for CK 7, pancytokeratin, EMA, and focally CEA, but only spindle cells reactive for vimentin, By electron microscopy, fibrous monophasic synovial sarcoma showed pseudogland formation with intercellular junctions of paired subplasmalemmal density and discontinuous basal lamina. These results suggest that the reactive type B synoviocytes and synovial sarcoma show an aberrant expression of the vimentin and CEA. The expression of CK on the resting and reactive type B synoviocytes and fibrous monophasic and biphasic synovial sarcomas are different. Type A synoviocytes expressing the MHC class II molecule and monocyte/histiocyte markers suggest a member of the mononuclear phagocytic system. The reasons of the aberrant expression of the intermediate filament, vimentin and oncofetal antigen, and CEA in reactively proliferative type B synoviocytes and synovial sarcoma and the different expression of cytokeratin on the resting, reactive type B synoviocyte and synovial sarcoma should be further evaluated.

Cystic adventitial disease of the popliteal artery is rare condition, but it is an important cause of peripheral vascular insufficiency in young men. Conventional angiography or MR imaging has traditionally been considered as the study of choice to diagnose this disease. We experienced a case of cystic adventitial disease of the popliteal artery that was diagnosed by 16-slice MDCT angiography, and this imaging modality displayed an accurate diagnostic capability for this disease.

ProSeal(TM) laryngeal mask airway (PLMA) was developed to be more effective especially with glottic airway sealing and is suppose to be an improved device over the classic laryngeal mask airway (cLMA). The PLMA's cuff is bulkier, softer, and more pliable than the cLMA. We reviewed a case were a patient had hand surgery under general anesthesia using the PLMA. After having the hand surgery, the patient suffered from dyspnea and had difficulty with their respirations at a supine position. The problems with dyspnea and respiration after surgery resulted because of difficulties from inserting PLMA No.5 into the patient. We suspect from this case that the problems in dyspnea and respiration were due to the folded cuff and incomplete placement of the PLMA, which resulted in lacerations of the mucosa in the soft palate of the patient. In this paper, we considered the probable causes for lacerations of the mucosa in the soft palate and reviewed all of the relevant literature, especially about the proper placement of the PLMA.
