This is an analysia of 126 cases(14.1%) of segmental vitiligo among 892 vitiligo patient who had visited vitiligo special clinie in Severance Hospital. The results are summarized as follow : 1. There were 53 males(42.1%) and 73 females(57.9%). 2. The mean age of onset was 15.4 years, the mean age on the first visit was 19.3 years, and mean duration of the disease was 4.8 years. 3. Mode of onset was single in 86.5% and the disease was table in 57.1% of patients at the visit. 4. The mean percentage of depigmented lesions was 3.3% and less than 5% of body surface area was involved in 86.5% of patients. 5. The most common site of involvement was head and necl(59.6%), especially face(43.7%) and the trigerminal dermatome was most commonly involved. 6. Poliosis was observed in 39.7%. 7. Family history of vitiligo was obtained in 11.1% of patients. There was no precipitating factors in 126 cases prior to development of vitiligo. 8. Koebner phenomenon was found in 4% of patients. 9. Association with diseases of a proven or suggested allergic or immunologic etiology including atopic dermatitis, halo nevus, uveitis, thyroid disease, lopecia areata and premature graying of hair was found in 10.3% of patients.

Ninety black C 57 BL mice were divided into control and photochemotherapy groups. Control group was subdivided into a UVA 1rradiation only subgroup and a khellin only administration subgroup, while the phototherapy group was subdivided into one TMP and two khellin administration subgroups with dosages of 1.5mg/kg, 5mg/kg and 20mg/kg, respectivly. UVA was administered three thimes a week in a dose of 4J/cm for 4 weeks. Skin biopsies were taken at 0, l, 2, 3 and 4 weeks and the split DOPA stain was employed to observe pigment production. The number, size and circumference of the melanocytes were assessed. In summary, our results inclicate that khellin, which is slightly less effective than TMP at the same effective dose, is quite effective for pigment production and the degree of the production is dose related.

PURPOSE: Sexual differences in the incidence and crystalline composition of urinary stones in humans are well-known, but it is unclear why men have a higher incidence of calcium oxalate stones than women. We investigated the effects of male sex hormones on stone formation using an ethylene glycol (EG) - induced urolithiasis model in rats. MATERIALS AND METHODS: Adult male Sprague-Dawley rats were divided into 4 groups, each containing 10 rats. One group of rats was left untreated and served as control. The other 3 groups were fed a 1% ethylene glycol (EG) lithogenic diet for 4 weeks. Among these, one group was non-castrated, one group was castrated and one group was non-castrated and given finasteride orally. Serum testosterone, creatinine, electrolytes, 24-hour urine levels of oxalate and citrate, and creatinine clearance were measured. The crystal deposits were examined by light and polarizing microscopes. RESULTS: Testosterone promoted calcium oxalate stone formation in EG - treated rats. Finasteride administration significantly decreased urinary oxalate excretion and calcium oxalate deposition, compared with controls. Urinary citrate was significantly decreased in EG-treated rats, but was not influenced by castration or administration of finasteride. There were no significant differences in serum concentrations of creatinine, sodium, or potassium among the control and experimental groups. CONCLUSIONS: Our data suggest that testosterone promotes calcium oxalate stone formation, and that dihydrotestosterone may be partially responsible for the exaggerated hyperoxaluria in EG-treated rats. Additionally, male sex hormones have a lesser influence on urinary citrate than oxalate.

Sjogren's syndrome has been considered to be an autoimmune disease affecting various organs including salivary and lacrimal glands. It occurs most commonly in middle-aged women, and less than 20 cases with primary Sjogren's syndrome have been reported in children. An 11-yim-old boy presented with recurrent annular erythema on the face that had been present for 2 years. A schirmers test showed a positive result. ANA was detected at a dilution of 1:640. Anti-Ro/SSA and anti-La/SSB antibodies were also detected. On histological examination, lymphocytes were infiltrated in the periappendegeal areas as well as the papillary and reticular dernis. The skin findimg is uncommon in children, but has become a characteristic feature of childhood Sjogrens syndrome with anti-Ro and/or anti-La antibodies.

We present a case of carcinoma erysipelatoides which or iginated from an internal organ. The patient was a 50 year-old female who had peritoneal carcinomatosis, She presented an erythematous lesion resembling erysipelas on her right breast. Histopathologic findings were consistent with metastatic adenocarcinoma but clinically it was not associated with carcinoma of the breast.

Although nearly 100 cases of prurigo pigmentosa have been reported in Japan, there has been no report in Korea. Recently, we exporienced two cases of prurigo pigmentosa in Korean women of 27 and 20 years of age. Histopathological findings of reddish papules showed exocytosis, inter and intra-cellular edema in the epidermis, liquefaction degeneration of the basal cell layei and perivascular round cell infiltration in the dermis. The specimens from the pigmented lesions show merely incontinence of pigments and mild perivascular round cell infiltration. We treated two patients with oral antihistamines and topical corticosteroids. One patient showed complete regression after 8 months of treatment but the other patient was lost for follow up.

Hydroa vacciniforme is a very rare photosensitivity disorder. The primary skin lesion is a vesicle or bulla which then heals with vacciniform scarring. We report a case of hydroa vacciniforme recurred after 3 years period of quiescence in a 20 year-old man who had had history of the disease from the age of two. The duplication of the natural lesion, clinically and histologically, was successfully made by artificial UV-A irradiation on the patient's back.
