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.

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.

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.

The gastrointestinal lymphoma is a well known entity for bleeding or perforation during treatment, but spontaneous perforation is not common. We report the CT findings of an unusual case of small bowel lymphoma which presented with massive pneumoperitoneum following spontaneous perforation.

A case of Osteogenic sarcoma arised from orbit 4 years after the radiation therapy for retinoblastoma in a 9 years old girl is presented. 4 Years ago, under the diagnosis of retinoblastoma, the left orbital exenteration was performed and was treated with x-ray radiation giving 4.500 gamma tumor dose in 4, weeks. On admission, the left orbital cavity was filled with hard mass and orbital bone revealed extensive destruction with osteoplastic changes on x-ray, and diffuse sarcomatous growth of anaplastic cells with abundant osteogenesis and osteoclastic activity microscopically. It is of authors' opinion that osteogenic sarcoma of orbital bone in this presented case might developed by irradition on retinoblastoma.
