A 43-year-old male patient visited our clinic complaining of persistent erythematous skin eruptions on the anterior chest, abdomen, and back for 10 years. Reticular erythematous mucinosis (REM) syndrome was diagnosed by the clinical and histopathologic features. Mucin deposition is much more conspicuous in papular lesions than in plaque lesions. Therefore, we suggest that the papular lesions may show the characteristic changes of REM and that a biopsy specimen should be obtained from a papular lesion for proper diagnosis of REM syndrome.

Computerized Tomography can make accurate diagnosis in most of the mediastinal tumors and cysts by assessingtheir location, shape and internal architecture. Authors analysed and present CT findings of 89 surgically provenmediastinal tumpors and cysts that were studied and treated in Seoul National University Hospital during recent 5years. The results are as follows; 1. The most common tumor was teratoma(25 cases). Neurogenic tumor (20 cases),thymic tumor or cyst (16 cases), lymphoma(7 cases), bronchogenic cyst (6 cases), intrathoracic goiter (6 cases),pericardial cyst(3 cases) and cystic hygroma(2 cases) were next in order of frequency. 2. The most constant findings of teratoma was thick walled cystic area(100%), while pathognomonic fat and calcified density were seenonly in 52% and 48% of cases, respectively. 22 cases were located in anterior mediastinum, 2 cases were inposterior mediastinum and a case is in middle mediastinum. 3. There were 20 cases of neurogenic tumor consiting of6 neurilemmomas, 7 ganglioneuromas, 4 neurofibromas, 1 ganglioneuroblastoma, 1 neuroblastoma and 1 malignantschwannoma. Most of them were located in posterior mediastinum with exception of 2 neurilemmomas arising from leftvagus nerve and left recurrent laryngeal nerve in middle mediastinum. Cystic change was seen in 2 cases ofneurilemmoma and in a case of ganglioneuroma. Calcification was seen in 3 cases, of neuroblastoma, aneurilemmoma,and a ganglioneuroma. 4. There were 11 cases of thymoma showing homogeneous solid mass with speckeldcalcification in 4 cases and irregular cystic change in 3 cases. 2 cases were invasive thymoma and myastheniagravis was present in 4 cases. A case of thymolipoma and a case of thymic cyst were included. 5. Lymphoma(2Hodgkin's and 4 non-Hodgkin's) appeared as lobulated, matted mass in anterior mediastinum especially inprevascular area expnading bilaterally. 6. Intrathoracic goiter appeared as slingtly high density mass within termingled calcification and cystic area in 5 cases of secondary goiter and homogeneous high densitymass(100-110 H.U. in precontrast scan) in a case of primary goiter. 7. Among the 6 bronchogenic cysts, 3 werelocated in subcarinal area, 2 were above carina and one was in left hilar area. 3 cases showed high CT number morethan 70 H.U. and others showed water density. 8. 3 cases of pericardial cyst were located in right cardiophrenicangle and all of them showed water density. 9. 2 cases of cystic hygroma were located in superior mediastinum,with extension to lower neck and all of them showed water density.

Fat containing masses, except mediastinal lipomatosis, of the thorax are uncommon. In spite of uncommonoccurences, as CT can detect not only the fat content but also the presence and character of the non-fattycomponent of the mass, accurate preoperative diagnosis can usually be made in most cases of fat containingmediastinal masses. Authors report 6 cases of fat containing mediastinal masses, that were diagnosedpreoperatively by CT scan, comprising 2 cases of limpoma(combined with plexiform neurofibroma in a case), 1liposarcoma, 1 thymolipoma, and 2 cases of omental hernia through Morgagni foramen.

Our hospital has been experienced pulmonary edema during general anesthesia for cesarean section of pre-eclampsia. But, the patient recovered rapidly without complication. Therefore, we think that before anesthesia, accurate laboratory data and careful attention are needed for general anesthesia of pre-eclamsia.

BACKGROUND: Recently, it has been suggested that autoantibodis face of melanocytes are prevent in the sera of vitiligo patients. However, these autoantibodies exist, whether they are specific for vitiligo a vitiligo patients possess them. In addition, the specificity of the iti lecular weight of the antigen are all unsolved areas demanding further. OBJECTIVE: To investigate the possible role of autoimmune microvitiligo, this study was designed to verify the presence of auto and vitiligo antigen from the surface of melanocytes, the specificity of gene specific antigens on the sunever, it is not known whether ents, and what percentage of goantigen and the exact moier research. anisms in the development of bodies in vitiligo patients, the utoantibodies and vitiligo anti. METHODS: Indirect immuvofluorescent microscopy, flow cytoriiety, and ELISA was done to compare the reactions between melanocytes and sera. SDS-PAC island immunoblotting were used for the identification of vitiligo antigen. RESULTS: Vitiligo sera showed more prominent fluorescence and higher optical density on the surface of melanocytes than normal sera. Forty-four percent of vitiligo sera was directed to melanocytic surface antigen with a molecular weight of 65kDa. The sition assay using rabbit antimelanocytic antibody showed an inhibition of the reaction betw er vitiligo sera and melanocytes in ELISA and immunoblotting. CONCLUSION: A surface antigen of 65kd was identified from melanocytes and 44.4% of the vitiligo sera showed positive reactions to this antigen.

The characteristic radiographic and CT findings of Iobar atelectasis are well known. However, Iobar atelectasis is a dynamic process, and atypical presentations may occur due to a number of different causes. Familiarity with the various typical and atypical radiographic findings of Iobar atelectasis is important for correct diagnosis. The aim of this manuscript is to illustrate the spectrum of radiographic findings of Iobar atelectasis and to correlate the radiographic findings with the CT findings. The review will illustrate examples of typical and atypical Iobar atelectasis, including combined Iobar atelectasis, peripheral Iobar atelectasis, migrating Iobar atelectasis, rounded atelectasis involving the entire lobe and Iobar atelectasis mimicking paravertebral and mediastinal masses.

BACKGROUND: The clinical behavior of vitiligo has not been clearly understood and hypothesis concerning the pathogenesis of the disease has been confusing and contradictory though autoimmune mechanisms have been considered important by many authors. OBJECTIVE: The purpose of this study was to develop a better understanding of the clinical features and pathogenesis of vitiligo. METHODS: We investigated clinical features of vitiligo in 1315 patients, and also compared the clinical course and features of non-segmental type(type A) and segmental type(type B) vitiligo patients to see whether the two types of vitiligo have a different pathogenic mechanism. RESULTS: Previously reported clinical patterns of the disease were reviewed and compared with our data, and the different clinical findings between the two types which supported the hypothesis of Koga et al. that type A and type B vitiligo had a different pathogenesis and autoimmune mechanisms played a role only in type A were shown. CONCLUSION: We investigated the clinical characteristics of vitiligo in Korea and showed that the type A vitiligo might have a different pathogenic mechanism with type B.
