The authors reviewed 7,065 new outpatients who visited the dermatology clinic of Gyeongsang National University Hospital in Chinju from Jan. 1st, 1987 to Dee. 31st, 1990 to study the prevalence of common dermatoses in this region as compared to other regions in Korea, The results suggest that age, sex, monthly and yearly distribution patterns around Chinju are similar to those of other areas in Korea except for higher prevalences of vitiligo, psoriasis, alopecia, and for lower prevalences of scabies, insect bites, and syphilis.

OBJECTIVE: p16INK4 and p15INK4B genes are known to be tumor suppressor genes which reside in p21 region of chromosome 9 and are related to cell cycle control as an inhibitor of cyclin-dependent-kinase. We designed this study to search for deletion and decreased expression of p16INK4 and p15INK4B genes in advanced ovarian carcinomas. METHODS: Polymerase chain reaction (PCR)-based analysis was performed to search for deletion of p16INK4 and p15INK4B using DNA extracted from frozen tissue in liquid nitrogen of thirty-one advanced ovarian carcinoma patients. The intensities of PCR bands were analyzed using an imaging densitometer to determine gene dosage in tumor samples and the relative gene dosage was calculated by comparing band intesity of p16INK4 or p15INK4B with that of beta-globin gene. Homozygous deletions were assigned to tumors in which the ratio was reduced to less than 25% in any one of exons of p16INK4 and p15INK4B. Immunohistochemical techniques were used to study the expression of p16INK4. p16-negative cells were characterized by the absence of nuclear staining, whereas cytoplasmic staining was variable. Clinico-pathologic features, complete remission rates and survivals were analyzed according to the status of p16INK4 and p15INK4B genes. RESULTS: Homozygous deletion of p16INK4 was detected in 12.9% of advanced ovarian carcinoma patients and that of p15INK4B in 35.5%. Clinico-pathologic features such as FIGO stage, histological grade, serum CA-125 levels were not different from groups with homozygously deleted p16INK4 and p15INK4B to those with normal genes. The survival of patients (13 [6-20] months) with homozygously deleted p16INK4 was significantly shorter than that (30 [8-52] months) of patients with normal p16INK4 (p=0.046; Log-rank test). CONCLUSION: These observations indicate that deletions of p16INK4 and p15INK4B gene might be involved in tumorigenesis of ovarian carcinoma and could be useful as a prognostic factor. A prospective, controlled study with more patients will be mandatory in the future.

A 20-year-old female, who had been treated with topical PUVA therapy for her vitiligo, developed characteristic skin lesions of disseminated superficial artiric porokeratosis(DSAP). All of her three sisters had vitiligo and had been treated with topica PUVA, hut only one developed DSAP lesion. Her mother had had DSAP lesions on expcsec areas for 20 years. DSAP shows an autosomal dominant mode of inheritance, and is charaterized by multiple ciark brownish keratotic papaules surrounded by slightly elevatied order. The exacerbation of the lesion by exposure t.o UV lignt indicates that the regulatingene for DSAP is related to sunlight. 1-lerein we reported a case of DSAP induced by topica] PUVA therapy in one patient during management of familial vitiligo in 3 sisters.

We report two cases of Darier's disease improved with Etretmate in the 44-year-old father and his 18-year-old son. Clinically, multiple dirty brownish, verrucous, discrete or confluent papules and plaques were noted on their back, abdomen, and face. Histopathologically, both of them demonstrated hyperkeratosis, suprabasal acantholysis, acantholytic cells in the lacunae, corpsronds, grains, and dyskeratotic cells. Oral Etretinate 30mg daily was given in both cases with remakable improvement 3 weeks after treatment. Six months later, they showed almost total clearin, of their skin lesions. No specific adverse effect was noted. There has been no evidence of recurrence for 6 months follow up period.

A 29-year-old woman had multiple, umbilicated papules on her fingers for 2 months. Skin biopsy specimen showed transepidermal perforation filled with plug of cellular debris, degenerated collagen and mucinous material. In the dermis, there were necrobiosis and peripheral palisading of mononuclear cells. Special stainings including masson's trichrome, alcian blue, acid orcein, and PAS showed necrobiotic collagen fibers and acid mucopolysaccharides on the necrobiotic zone and trasepidermal elimination canal. Topical application of 0.05% Clobetasol-17-propionate ointment improved her lesion.

Calcifying aponeurotic fibroma is a rare benign tumor found primarily on the hands or wrists of children and adolescents. It has a tendency of local invasion, and a high recurrence rate after excision. An 11-year-old boy had a hard indurated. 3 x 3cm-sized, nodule on the right sole for 3 years. A biopsy specimen showed heavy focal calcification within areas of densely paked stromal fibroblastic cells. Some fields contained multinucleatec giant cells and chondroid metaplasia. There were infiltrative growth patterns of fibroblastic cells extending into the adjacent adipose tisse and blood vessels. There was no evidence of reccurence at 3 months after the operation.

A 49-year-old male had erythematous to rusky red papules, indurated plaques and lichenified patches with hyperpigmentation on sun-exposed areas for 6 years. Phototest revealed the decreased rninimal erythemal dose to UVA(10J/cm. Photopatch test with 5% Trandate ointment, 5% hydrochlorthiazide ointment and vaselin. as a control were all negative. Two weeks after cessation of Trandate, an oral challenge of hydrochlorthiazide followed by phototest was perfrirmed resulting in exacerbation of skin lesions and photosensitivity with a decreased MED to UVA(10J/cm) again. After the cesation of Trandate containing hydrochlorthiazide, the skin lesions were improved with complete loss of photosensitivity. But, improvement of the infiltrated or licheified plaques were delayed. Presenile cataract previously noted in the patient seemed to be related to his longstanding intake of hydrochlorthiazide.
