Lymphangioma circumscriptum was known as very rare disorder in our country. The patient was 28 year old man had been affected grouped papulovesicular lesion on right arm without subjective complaint. Histopathological finding shows in the upper most portion of the dermis cystically dilated lymph vessels lined by a single layer of endothelium. They contain coagulated lymph and lymphocytes. Over some of the lymph cyst it is thinned, elswhere it may show focal acanthosis, hyperkeratosis.

BACKGROUND: It is a recent trend in Korea that the uses of trichloroacetic acid(TCA) have been increased as the usual chemical peeling agent for treating abnormal pigmentation like solar lentigo, freckle, melasma, or actinic keratoses, rhytides, acne scar and other facial problems. We made an experiment to see how the different concentrations of TCA affect the guinea pig skin histologically. OBJECTIVE: The purpose of this study was to evaluate the histologic changes using various concentrations(35%, 50%, 90%) of TCA. METHODS: At first, 35%, 50% or 90% of TCA was applied to the each right ear of guinea pigs. After the application, we checked these specimens in intervals - one hour after (D1hr), the following day(D1), the third(D3), fourth(D4), fifth(D5) day, one week(D1wk), two weeks(D2wks), six-teen weeks(D16wks) later. The specimens were processed and stained with hematoxylin and eosin (H & E), Verhoeff elasic, and alcian blue stain. RESULTS: 1. In Do1hr of 35% and 50% TCA treated groups, some keratinocytes with eosinophilic cytoplasm and pyknotic nuclei were scattered in the epidermis. The higher the concentration of TCA, the more evidence of homogenization of the epidermis. The homogenization of epidermis and dermis was most prominent in 90%. 2. In D1 and D3, necrosis of the epidermis was proportional to the concentrations of TCA. We could see infiltrates of inflammatory cells in the whole dermis-when 90% of TCA was tried. 3. Desquamation of the necrotic epidermis appeared in each group between 3 and 7 days after the treatment. 4. In groups treated with 50% and 90% TCA, reepithelialization arising from skin appendages was prominent. 5. Hyperplasia of epidermis appeared in every group between the second and sixteenth weeks but dermal hyperplasia was prominent only in the group of 90% TCA at sixteen weeks. CONCLUSION: While thirty-five per cent TCA solution produced partial destruction of the epidermis, 50% and 90% of TCA destroyed the entire epidermis and upper dermis. Regeneration of epidermis from skin appendage is a signficant base of deep chemical peeling. Epidermal hyperplasia was found in 50% and 90% of TCA, but dermal hyperplasia was only found in 90% of TCA.

In order to grasp the real status of male sterility of the Koreans, clinical observation, semen analysis, and testicular biopsy were conducted on 257 cases. the study was performed in the Department of Urology, Kyungpook National University School of Medicine during the period from April 1963 to March 1968 for5 years. 1) The 257 cases complained of sterility occupied 4.3% of the total number of outpatients, 5927. visited during the observation period. 2) The age range of the cases applied was from 55, maximum, to 21. minimum, with the category of 26 to 35 occupying 2/3 of the whole. 3) The majority of the cases were in the 2nd to 5th year of their marriages 10.8%. 4) Cities were found to produce more of such cases than the country. and no specific relationship was revealed to be connected with patient's occupations. 5) Tuberculous diseases weremore prevalent in the past histories of those involved, and gonorrhea and mumps showed a decreasing tendency. 6) 141 cases (55.2%) produced 2 to 4ml of semen amount and 40 cases, less than 1.0ml. 7) 90 cases (35.O%) were found have azoospermia and 122 cases (47.7%) had more than 50 X 10(6) sperms, 8) 106 cases (63.5%) had higher than 60% of active sperm while 16 cases showed to have less than 20%. 9) Findings of testicular biopsies were conducted on 35 cases with azoospermia of oligospermia: Germinal cell aplasia-17 cases (48.6%); spermatogenic arrest-10 cases (28.6%); hypospermatogenesis-6 cases (17.1%); normal-2 cases.

A clinical study was made on 47 cases of undescended testes during 9 years, from March 1973 to February 1982. The results obtained as follows: 1. The age distribution varies from 3 to 35 and 12 cases (26%) were between 21-25 years old. 2. Bilateral undescended testes were found in 8 cases, and in the cases of unilateral, right in 27 cases and left in 12 cases. 3. Of the 57 undescended testes, most popular location was inguinal type in 31 testes. (56.4%). 4. Hormonal therapy was done on 11 cases and among them only 2 cases of unilateral type responded with partial descent. 5. Orchiopexy was performed on 45 cases and orchiectomy on 2 cases. 6. Of the several methods of orchiopexy, dartos pouch method revealed high success rate (91%).
