A clinico-pathological study on the true skin appendage tumors was carried on the accumulated cases during pat 11 years from 1976 to 1986 years in the Department of Pathology, Seoul National University Hospital. The results was as follows; 1) Among various benign skin appendage tumors pilomatricoma was the most common benign tumor consisting of 72 out of 244 cases (30.1%), followed by dermoid cyst 48 cases (20.0%), steatocystoma multiplex 37 cases (15.5%), syringoma 33 cases (13.8%) and trichilemmal cyst 19 cases (0.8%). Other benign skin appendage tumors were rarely noted under 3%. Sebaceous carcinoma was most common among malignant skin appendage tumors and no malignant tumor of sweat gland origin was noted. 2) The sex ratio of male to female of the pilomatricoma was 1 : 2.6 and on the face, neck, and extremeties in 1st and 2nd decades. The sex ratio of dermoid cyst was 1 : 1.2 on the face in 1st decade. The sex ratio of steatocystoma multiplex was 1 : 1.9 and on the trunk in 3rd decade. The sex ratio of syringoma was 1 : 7 and on the face in 5th decade. The sex ratio of trichilemmoma was 1 : 1.6 and on the trunk in 5th decade. Other tumors were not avaiable for analysis because of small number. The sex ratio of sebaceous carcinoma was 1 : 2 and on the eyelid in 6th decade

Benzene and toluene, which are widely used aromatic hydrocarbons in workplace, are recently proved to cause health hazards due to their toxic effects. This study investigated the influence of toluene on the urinary excretion of benzene metabolite by administering short term exposure limit(STEL) of these compounds(i.e., 13.8mg/kg of benzene and 108.8mg/kg of toluene) intraperitoneally into Sprague-Dawley rats. After administration, urinary phenol concentration of rat was measured by gas chromatography for every three hours. Data were analyzed by non-parametric statistical methods using Kruskal-Wallis multi-sample test and Mann-Whitney U test. The following results were obtained: 1. Administration of STFL-benzene increased urinary phenol concentration in rats. 2. Urinary phenol concentration was increased logarithmically according to the dosage of benzene. 3. Excretion of phenol in urine was decreased when benzene and toluene were administered simultaneously compared with administering benzene alone. In Summary, these results reveal that administration of STEL of toluene has antagonistic effect of urinary excretion of benzene metabolite in rats.

We report an unusual case of a sigmoid colon perforation after ventriculoperitoneal shunt surgery. Distal catheters are known to cause perforation in the setting of colonoscopy. The exact pathogenesis of this complication is not clear, but it can cause serious complications. Hence, patients require prompt and aggressive management, including laparotomy with bowel wall repair, catheter removal, and antibiotic therapy.
