A statistical study was done on 2205 skin tumors filed at Department of Clinical Pathology, Han Kang and Kang Nam Sacred Heart Hospital during last 10 years from 1980 to 1989. The results were summarized as follows : 1. The number of skin tumor surveyed was 2205 among total 67931 biopsy specimens, 2052 benign skin tumors, 153 malignant tumors. 2. The specimens were requested from the Department of Surgery(707 cases, 32.1 %), Dermatology(618 cases, 28.0%), Plastic Surgery(354 cases, 15.79o), and Or thopedic Surgery(223 cases, 10.1% ). 3. Among 2052 benign skin tumors, the frequently observed tumors were epidermal cyst(577 cases, 28.1%), lipoma(398 cases, 19.4%), melanocytic nevus(121 cases, 5.9 %), dermatofibroma(74 cases, 3.6%), cavernous hemangioma(72 cases, 3.5%), ea.ch of pilmatricoma and neurofibroma(63 cases, 3.1% ), granuloma pyogenicum(57 cases, 2.8%), neurilemmoma(53 cases, 2.6%), seborrheic keratosis(45 cases, 2.2%), soft fibroma(45 cases, 2.2%). 4. Among 153 malignant tumors, the frequently observed tumors were squamaus cell carcinoma(50 cases, 32.7%), basal cell carcinoma(45 cases, 29.4%), malignant melanoma(8 cases, 5.2%), Bowens disease(7 cases, 4.6%), metastatic skin tumors(7 cases, 4.6%) in order. Male to female ratio of malignant tumors was 1.6:1 and the peak age incidence was in 6th decade. 5. Male to female ratio of squamous cell carcinoma was 3.2:1 and of basal cell carcinoma 1: 1.3. The peak age incidences of both squamous cell carcinoma and basal cell carcinoma were 6th decade. The predilection sites of squmous cell carcinoma were face, neck and genitalia and those of basal cell carcinoma were face, lower extremities, neck and trunk.

Nickel is widely known throughout the world as a common source of contact dermatitis. Korea is one of the rapidly developing countries where the use of nickel and nickel by-products is on the rise. Lacking in ore, Korea imports most of its nickel. In the last ten years, in relation to rapid industrial development, the amount of nickel imported has increased over 1, 000 times. Nickel dermatitis is becoming an increasing problem in the patch test clinic. With regards to this, we have tried the dimethylglyoxime spot test to all materials mentioned in the textbooks which are regarded as nickel sources in other industrialized societies, so as to make an up-to-date list of nickel sources applicable to Korea. In addition, we have also included traditional nickel sources such as acupuncture needles, fire pot, old and new coins and chest of drawers etc. We also have analyzed data concerning nickel imports to Korea during the past 10 years.

Author had already reported that urinary excretions of several electrolytes of rural Korean measured in late 1970`s were different with that of the 1960`s. This study was carried out to evaluate the difference of daily urine volume, urinary excretions of sodium and potassium between urban and rural residents in Korea. 20 urban and 28 rural residents were selected arbitrarily and the surface areas of both group didn`t show any difference. 24 hour urines were collected and sodium and potassium concentrations were analyzed by means of flame photometry. Followings were the results. 1. Daily urine volume urban residents: 1578.75 461.92 ml/day, rural residents: 1582.14 417.91 ml/day 2. Daily urinary sodium excretion urban residents: 223.95 109.61 mEq/day, rural residents: 219.68 65.60 mEq/day 3. Daily urinary potassium excretion urban residents: 75.44 28.00 mEq/day, rural residents: 49.52 14.95 mEq/day Above results reveal that daily urine volume and urinary excretion of sodium of urban residents are within the range of rural residents, while daily urinary potassium excretion of urban are much higher than that of rural one. In addition, the ratio of K/Na of urban residents is also much higher than that of rural residents and than that of 1960`s, although the ratio was still lower than those of Westerns.

Daily excretions of sodium, potassium and urea nitrogen and urine volume of normal Korean were reported by several authors. However, it is generally suspected that dietary composition of Koreans improved during last decade. Author have hypothetized that changes of diet composition could modify urine compositions and volume. In order to determine the urine composition and volume in the late 1970`s, sodium and potassium concentrations were measured by flame photometry and urea nitrogen by urease indophenol method in the urine from 50 rural residents. The residents were composed of 10 public officials, 18 male farmers and 22 female farmers. Followings were the results: 1. Daily urine volume Total average : 1594.20+/-443.89 ml/day, Public official : 1714.00+/-548.00 ml/day Male farmer :1508.89+/-310. 54ml/day, Female farmer: 1612.27+/-496.04 ml/day 2. Daily urinary sodium excretion Total average : 5.19+/-1.21 g/day. Public official : 5.62+/-1.93 g/day Male farmer : 4.73+/-1.10 g/day, Female farmer: 5.37+/-0.98 g/day 3. Daily urinary potassium excretion Total average : 1.79+/-0.59 g/day, Public official : 1.97+/-0.60 g/day Male farmer : 1.91+/-0.59 g/day, Female farmer : 1.62+/-0.58 g/day 4. Daily urinary urea nitrogen excretion Total average : 7.26+/-l.95 g/day, Public official : 8.06+/-1.65 g/day Male farmer: 7.53+/-2.40 g/day. Female farmer : 6.67+/-1.65 g/day A comparison of these data with corresponding figures obtained from Western reporters indicate that the concentration and excretion of sodium of rural Koreans are still higher significantly, while those of potassium and urea nitrogen are lower than those of Westerns significantly. On the other hand, a comparison with corresponding figures obtained from other Korean reporters in the 1960's indicate that sodium excretion of present data is lower while potassium and urea nitrogen are higher than those of the 1960's. It is speculated that these peculiarities of urinary composition shown in rural Koreans in the late 1970's are attributed to improved protein ingestion combined with decreased salt intake as compared to 1960's, however, the levels are still far from Westerns.
