We experienced three cases of non-giant congenital nevus. They showed zosteriform or heart-shaped grouping of pigmented papules which were pierced by hairs. Histopathologic examination disclosed nevus cell infiltration in and around hair follicles and in the upper two thirds of reticular dermis. We would like to report these cases as follicle-centered spotted grouped pigmented nevi.

We present herein a case of sebaceous hyperplasia in a 55-year-old male, who showed multiple asymptomatic yellowish papules on the forehead and the cheeks. Histopathologic examination of a papule revealed numerous sebaceous lobules grouped around several enlarged sebaceous ducts. Three weeks of oral administration. of isotretinoin 40 mg per day brought marked improvement.

The 5-HT2A receptor is of great interest for research into schizophrenia and psychopharmacology in light of the observation that schizophrenic patients has 5-HT cortical-subcortical imbalance and atypical antipsychotic clozpine has 5-HT2A antagonists properties. An significant association between schizophrenia and the T102C polymorphism of the gene for 5-HT2A receptor has been reported. In this study, we investigated an association between schizophrenia and the T102C polymorphism of the gene for 5-HT2A receptor in Korean schizophrenic patients. The subjects consisted of 139 schizophrenic patients and 88 normal controls. Genomic DNA was amplified by PCR and digested with MsPI. The uncutt product identified allele 1(nucleotide sequence TCT) ; digested products of 216bp and 156bp identified allele 2(nucleotide sequence TCC). The allele frequencies and the genotypic distribution of 5-HT2A receptor gene were not significantly different between schizophrenic patients and normal controls. Since allele frequencies of the T102C polymorphism may differ between individuals of different ethnic backgrounds, it needs to be conducted in an advanced research.

PURPOSE: A new quantitative tumor marker, based on the combined measurement of urinary fragments of cytokeratins 8 and 18, namely the urinary bladder cancer antigen(UBC(TM)) test, has been proposed for the detection of bladder transitional cell carcinoma(TCC). We evaluated the diagnostic efficacy of UBC(TM) test in comparison with that of urinary cytology to establish UBC(TM) test for the diagnosis of TCC. MATERIALS AND METHODS: One-hundred ninety-six patients with hematuria were included in this study. Forty patients were diagnosed histologically as TCC by transurethral resection or radical cystectomy(group A), while the others had various benign urinary tract conditions(group B). RESULTS: UBC(TM) levels were significantly different between groups A (1851.39+/-4627microgram/l) and B (19.28+/-107.03microgram/l) (p<0.001). Sensitivity for diagnosis of TCC was 89.7%(36/40) in UBC(TM) test and 45%(18/40) in cytology(p<0.05). Specificity for diagnosis of TCC was 84.6%(132/156) in UBC(TM) test and 100%(156/156) in cytology. UBC(TM) test was significantly more sensitive than cytology in stage Ta(85.7% vs. 0%, p<0.05), T1 tumors(89.4% vs. 31.5%, p<0.05), and in Grades 1(83.3% vs. 25%, p<0.05) and 2(90.4% vs. 52.3%, p<0.05) tumors. UBC(TM) test was more sensitive in higher Grade(83.3% in Grade 1, 90.4% in Grade 2 and 100% in Grade 3). CONCLUSIONS: In comparison with urinary cytology, UBC(TM) test could be a valuable marker for diagnosis of TCC in patients with early stage and low grade TCC. Therefore, UBC(TM) test in association with cytology may be useful as a screening test for TCC of the bladder.

A 60-year-old woman has experienced of right upper quadrant abdominal discomfort. This partient took cholecytectomy due to gall stone 15 years ago. At that time microscopic finding the neck of gallbladder showed well differentiated papillary adenocarcinoma confined to superficial part of musele layer. 3 years before admission she took T-tube drainage due to obstructive jaundice. The microscopic finding af distal common bile duct showed well differentiated adenocarcinoma. Recently she complained of pain and discomfort on T-tube site and so we perforrned endoscopic retrograde biliary drainage after removal of T-tube. The computed tomogram showed no mass in liver or lymph node enlargement. 4 months after procedure of ERBD; we changed to the new catheter for the prevention of cloggiag of prosthesis. We report here a case of longterm survival over 15 years after the diagnosis of cancer of extrahepatic bile duct.

BACKGROUND: Neutrophils fixed on a slide are used in indirect immunofluorescence assay (IIF) for anti-neutrophil cytoplasmic antibody (ANCA). A simple method to prepare ANCA slides is described in this report. METHODS: This method uses an overlay method to separate WBC from EDTA whole blood and Octospottrade mark kits to cytocentrifuge WBC onto 8-well slides. This in-house ANCA IIF was compared with commercial ANCA IIF using 40 sera, and with enzyme linked immunosorbent assay for anti-myeloperoxidase (MPO) antibody (MPO ELISA) using 117 sera. RESULTS: In ANCA IIF parallel tests using 10 positive and 30 negative sera, in-house slides were in good qualitative agreement, 97.5% (39/40) with commercial kits (kappa=0.93). Fluorescence pattern and intensity of positive reaction was also highly concordant between two methods. In MPO ELISA positive cases, the positivity rate of in-house ANCA IIF was 97.8% (45/46), which accounts for its assay sensitivity for the presence of anti-MPO antibody. CONCLUSIONS: In-house ANCA slides was convenient and cost-efficient to be prepared. As these slides were found to have acceptable agreement and sensitivity as compared with commercial kits, in-house ANCA IIF is considered to be useful to screen ANCA in combination with MPO ELISA in routine clinical laboratory practice.
