Synovial sarcoma most commonly affects the extremities, especially the lower thigh and knee region. However, a smaller number develops in a central or axial distribution, an area which encompasses the trunk, orofacial, cervical and parapharyngeal regions. The retroperitoneum is an extremely unusual site and has never been recorded in the literature as primary a site for synovial sarcoma. We investigated a case of retroperitoneal synovial sarcoma in a 40-year-old woman. The specimen consisted of fragmented large bulky multinodular masses separated by slit-like spaces. The tumor was 130 gm in weight. Microscopically, the tumor was composed of nests of plump ovoid to polygonal shaped cells and bundles of spindle shaped cells, which had vesicular nuclei and a small amount of cytoplasm. In some areas, there were cleft like spaces and pseudoglandular structures lined by flat or cuboidal cells. Myxoid change, collagen deposition, foci of calcification and osseous metaplasia were also present. Immunohistochemically, the polygonal cells and some of the spindle cells reacted positively for keratin. The spindle cells, especially in the perivascular area were positive for vimentin. S-100 protein and GFAP were negative in both type of cells.

BACKGROUND: There have been many changes to the social and medical environment in Korea and many studies showed a steady increase of cutaneous tumors. But none of them included a data occurring from head and neck. OBJECTIVE: To investigate the incidence and distribution of the cutaneous tumors of the head and neck. METHODS: A total of 1,415 cases of head and neck cutaneous tumors were obtained from pathology specimen at Department of Dermatology between 2010 and 2014. RESULTS: Among 1,415 cases of head and neck cutaneous tumors, 871 cases (61.5%) were benign tumors, 271 cases (19.2%) were malignant tumors, and 273 cases (19.2%) were premalignant lesions. The most common benign head and neck cutaneous tumors was epidermal cyst with 188 cases (21.6%), followed by 173 cases (19.9%) of seborrheic keratosis, 71 cases (8.2%) of intradermal nevi. Among the 271 cases of malignant head and neck cutaneous tumors, there were 164 cases (60.5%) of basal cell carcinoma, 89 cases (32.8%) of squamous cell carcinoma, 5 cases (1.8%) of malignant melanoma. The predilection sites of malignant head and neck tumors were face (87.5%), ear (4.8%) and neck (4.0%). Of the premalignant lesions, there were 210 cases (76.9%) of actinic keratosis, 36 cases (13.2%) of Bowen's disease and 27 cases (9.9%) of actinic cheilitis. CONCLUSION: In our study, the proportion of malignant tumors and premalignant lesion in head and neck tumors was higher than previous reports. Also, the percentage of woman in malignant tumors and premalignant lesions was higher than man, unlike previous studies. However, these results had limitation associated with retrospective study in a single institution, and further prospective study with multi-center is required for confirmation.

The ESR is one of the oldest laboratory test still in use. Although it lacks specificity in diagnosis, it can be effective for monitoring disease activity and following-up. The Westergren method is used for reference method, however coefficient of variation has been described 0.8% to 22.9% according to the literature. Since the ESR was invented in 1921, measurement technique has developed and automated measurement is introduced. We analyzed one hundred forty-three patient samples using SEDIsystem' automated ESR measuring system and compared with modified Westergren and Wintrobe methods. Comparison between SEDIsystem' and modified Westergren for ESR measurement yields the following regression equation; y = 0.863x - 1.69 (r=0.830), SEDIsystem'M and Wintrobe y'= 1.14x - 14.7 (r=0.789), rcspectively. We repeated measurement to evaluate reliability, results are not significant in statistically. In conclusion, SEDIsysten' automated ESR measurement correlated with modified Westergren and Wintro" ; methods, reveal reliable results after 4 hours and can report rapidly for large samples. Thus, these results indicate that SEDIsystenT"' automated ESR measurement may be useful tool for clinical practice.

BACKGROUND: Elecsys 2010 immunoassay system is based on the electrochemiluminescence immunoassay using a ruthenium (II) tris (bipyridyl) label. Since it was the first time to use the system in our laboratory, we would like to evaluate the analytical performances (precision, linearity and recovery rate) and correlation with radioimmunoassay (RIA) and microparticle enzyme immunoassay (MEIA) methods. METHODS: We used precicontrol tumor marker (TM1, TM2) for alpha-fetoprotein (AFP), prostatic specific antigen (PSA) and carcinoembryonic antigen (CEA), Precicontrol universal (Ul, U2) for triiodothyronine (T3) and thyroxine (T4), Precicontrol-TSH for thyrotropin (TSH) and pooled serum for the evaluation of precision and recovery rate. Patients' sera were used for the linearity and comparison study. RESULTS: The coefficients of variatron of Imprecision study were below; 4.0%, 8.7% and 10.2%, respectively in the within-run, within-day and between-day analysis. The recovery rates were 100.5%, 96.1% and 102.5%, respectively in T4, TSH, and AFP. The linearity were y=1.02x-0.182(r=0.99) for T4, y=1.01x+0.12 (r=0.99) for TSH and y=1.01x+0.54(r=1.00) for AFP. T3, T4, TSH, CEA and PSA results showed good correlation with RIA (r>0.90), but AFP showed r=0.88. Also, AFP, CEA and PSA results showed excellent correlation with AxSYM (r>0.99). CONCLUSION: Elecsys 2010 immunoassay system showed excellent precision, recovery rate, clinically acceptable linearity and good correlation with the results obtained by RIA and MEIA methods.

Peri-vater divertieula may interfere with the normal flow of biliary and pancreatic secretion, thus leading to pancreatobiliary diseasa and the very presence of juxtapapillary diverticulum makes cannulation technically difficult and contributes to the low success rate. In this present series, the relationship between duodenal diverticula and age, sex, and biliary-pancreatic pathology was stud.ied in 1400 patients examined with ERCP. The results are as follows. 1) Duodenal diverticula was demonstrated in 73 of 1400 patients(5, 2%). 2) The incidence of duodenal divertieular increased with age and they were more frequent in men. 3) The cannulation of one or both duct system was suecessful in 69 of the 73 patients, the success rate was 94. 5%. 4) The biliary pathology was found in 41 of the 73 patients and the pancreatic pathology in 6 of the 73 patients. The rnost common finding was biliary calculi which were demonstrated in 35 patients(47. 9%).
