Aplasia cutis congenita is a rare disease presenting in the newborn infant as localized areas of skin defect. Its association with a number of congenital malformations is well documented. I observed a newborn infant with typical aplasia cutis congenita. The skin defect of my case was found on the posterior fontanelle without any congenital malformation. Diagnosis was made by history, clinical and histopathological findings.

This study was aimed to investigate the clinical manifestation of nail changes in psoriasis and was based on analysie of 205 p oriatics visited the department of dermatology, Seoul National University Hospital from November, 1984 to June, 1985. The results were summerized as follows: Nail changes were noted in 78(38. 0%) out of 205 patients in the finger nails. Toe nails were involved in 26(12 7%) cut of 205 patients. 2 Nail changes in male were noted in 49 (46, 7%) out of 105 patients and in female, 29(29%) out of 100 patients. 3. The peak incidence of nail changes according, to age group was over 40 years (45. 1%.) and the lowest incidence, under 9 years(26. 7%). 4, Pitting(57. 7%) was the commonest change ii the finger nails and subungal keratosis(50. 0%) and discoloration(46 2%) in the toe nails. 5 Incidence of nail changes according to psoriatic type was 23. 7% in guttate type, 42. 6% in nummular type, 53 3% in annular type. 6 The patients with the more severe degrees of psoriasis had a higher incidence of nail involvement. Mean duration of psoriatics with nail change and without nail change was 6. 3 years and 6. 5 years, respectively, 8 Among 65 patients with psoriatic nails, onychomycosis was noted in 9 patients(13.8%).

Since Epsteins report in 1963, which identified topical corticosteroid therapy as a possible cause of striae formation, many adverse effects resulting from topical steroids therapy has heen observed in dermatological practice. In this study, 365 cases of side-effects with topical steroids in Department of Dermatology, Chonnarn University Hospital from 1972 to 1981 were analyzed, and the results obtained can be summerized as follows; 1. During this pericd, themean average percent of side effects with topical steroids was 0.85 of the yearly total patients and 12 different kinds of side-effects were found to be present in this study. 2. The annual rate of increase of side-effects with topical steroids (2.4%) was higher than that of yearly total patients (0.5%) and the annual frequency of the 12 side-effects was shown in Table 1. 3. The frequency of the 12 side-effects by age group was shown in Table 2. 4. The frequency of the 12 side-effects by season, sex and region was shown in Table 8. 5. The frequency of the 12 side-effects by lesion site was shown in Table 5. 6. T.he mean period of application with topical steroids was 4. 18 months and applied topical steroids were betamethasone-17-valerate(30.4%), fluocortolone (22.7%), hetamethasone dipropionate(12.9%), fluocmolone acetonide (9.0%) and prednisolone(8.8%) respectively. 7. The most frequent topical steroids and period of application causing each side-effects were as follows: betamethaaone-17-valerate for 1 month resulting in Steroid acne, betamethasone-17-valerate for 2 months resulting in Telangiectasia rubeosis et steroidica, triamcinolone acetonide for 1 month resulting in Perioral dermatitis and betarnethasone-17-valerate for 11 months resulting in Atropic striae.

Leprosy has two polar types. The one tuberculoid leprosy (TL) is characterized by well preserved cellular immunity with a good prognosia and the other lepromatous leprosy(LL) shows no cellular immunity with a poor prognosis. The preaent study was designed to measure the activity of adenosine deaminase (ADA) in sera and erythrocytes of leprosy patients, as it's activities are known to be decreased in immune deficiency diseases. There were no significant differences in the erythrocyte ADA activities among normal subjects(9. 60+4. 43 units/1012 cells), TL patients (7. 12+2. 51 units/1012 cells) and LL patients(6. 96+0. 81 units/1012 cells), The ADA activities in sera of TL patients(20.15+2. 90 units/L) did not differ from those of normal subjects(20.44+ 2. 07 units/L), but the LL patients(17. 52+3. 30 units/L) showed a slightly lowered activity than those of normal subjects.

In the case of a soft tissue defect which requires thin & pliable tissues, the choice of donor site is limited due to flap bulkiness and donor site morbidity. To overcome these problems, a variety of perforator-based flaps such as paraspinous and parasacral perforator flap, deep inferior epigastric perforator flap, gluteal perforator flap, and thoracodorsal artery perforator flap have recently been introduced. We experienced 8 cases of soft tissue defects from December 1996 to March 1999 using the thoracodorsal artery perforator flap for reconstruction. We could elevate the cutaneous flap with preservation of the latissimus dorsi muscle flap only when it was based on one cutaneous perforator. Defatting procedure was possible for further thinning of skin flap. In one case, axillary defect after release of postburn scar contracture was repaired with island perforator flap and the other seven cases were repaired with free flap. The results were satisfactory. We believe the thoracodorsal artery perforator flap is useful for reconstruction of soft tissue defects which are large or under conditions requiring thin flap.

The tracheostomy is increasingly being performed. In most cases, the tracheostomy sites are left to heal by secondary intention, so it leaves a depressed and wide scar that is cosmetically disfigured. Another problem os that the scar is also attached directly to the trachea itself and will move vertically with the trachea during the act of swallowing. Even though the tracheostomy scar is cosmetically acceptable, the mobility and retraction of the scar is a continual nuisance to the patient. We performed a retrospective study on 9 patients who had undergone revision of the depressed thracheostomy scar by the Renner Method from June, 1997 to February, 1999. The method includes transverse fusiform incision of the original scar and excision of the depressed portion of the scar to the level of the trachea itself. To prevent attachment of the skin and trachea, a bilateral subcutaneous flap and muscle flap were simply advanced to the midline and overlapped. Then the rest of scar that was not depressed was deepithelized and flipped to augment the soft tissue volume in the central depressed area. Satisfactory results were achieved in all patients without hematoma, infection, hypertrophic scar, and keloid formation. We believe this simple Renner method is one of the best ways of performing posttracheostomy scar revision.

BACKGROUND: Sunscreens have been used widely to prevent the photosensitive skin diseases, skin cancer, and skin aging. However, no sunscreen blocks all kinds of effects caused by ultraviolet light(UVL), and the effect of sunscreens on the impairment of immune function by UVL irradiation is controversial. OBJECTIVE: We try to evaluate the efficiency of sunscreens for blocking the depletion of LC induced by UVB irradiation. METHOD: The ATPase positive LCs were observed in the skin of hairless mice(Hr+/Kud) irradiated by UVB with or without topical application of sunscreens. Two commercially available sunscreens with respective SPF 8 and SPF 30 were applied to the dorsal trunk skin. The mice were irradiated with different increasing doses of UVB at a single time. RESULTS: The ATPase positive LCs in the irradiated dorsal and ear skin were significantly de-creased in densities according to the dosage, and apparently revealed a loss of their dendrites, granulation, and clumping from a UVB dose of more than 60mJ/Cm2. With both sun-screen treatment on the dorsal trunk before irradiation, the densities of LCs on the dorsal skin were significantly higher compared to the un-treated groups at all ranges of UVB doses in spite of a dose dependent decrease in their density. However there was no significant difference on their preventive effect between both sunscreens(SPF 8 and SPF 30) except at high UVB dos-es of more than 240mJ/Cm². CONCLUSION: The LC depletion induced by UVB can be partially protected through the topical application of a sunscreen at a UVB dose dependent fashion. However SPF(sun protective factor) dose not appear to be a good indicator for evaluating sunscreens immunologically.

Juvenile xanthogranuloma is characterized by one, or oftener many, yellow, re3dish yellow, or, brown 4-to-20 mm papules or nodules on the face, scalp, trunk, and mostly, extensor surfaces. It may involve internal organ besides the skin such as eye, gastrointestinal and genitourinary tracts. anthogranuloma in adult is usually solitary and dose not involve organs other than skin, and generally dose ncit resolve without treatment. Histopathologically, characteristic Touton giant cells usually appear numerously. We report a case of juvenile xanthogranulorna which occured on scalp of 49 year-old male showing typical clinical and histopathological findings.

Leiomyosarcoma arising in the skin is rare tumor, and diagnosis usually is made microscopically. After local excision, these lesions recur in large proportion of pat ients. The authors herein report a 53-year-old male with leiomyosarcoma appeared in the skin of the right forearm and presenting as a dark reddish colored, 5*6cm in diameter, superficial ulcerated single firm nodule with intermittent pain. Histopathological examination showed poorly circumscribed tumor consisting of interlacing bundles of spindle shaped smooth muscle cells in the middle and lower parts of the dermis. The nuclei were hyperchromatic, large, vacuolated, and irregular in shape. Electron microscopic findings revealed cytoplasmic organelles such as rough endoplasmic reticulum and mitochondria of malignant smooth muscle cells in the paranuclear area, Characteristic subsarcoelmmal caveolae and dense plaque were noted and myofilaments were distributed in the peripheral cytoplasm. The tumor did not recur in 10 months' follow-up.
