The pathogenesis of vitiligo has not been fully elucidated, but three different hypothese have been advanced to explain the cause of vitiligo. One is related to autoimmunity, another concerns neurohumoral factors and the third involves self-destruction of melanocytes. The autoimmune theory of vitiligo is further strengthened by the increased association of vitiligo with a nurnber of autoimmune disorders and by the increased prevalence of organ-specific autoantibodies in vitiligo. Also decreased T lymphocytes in vitiligo patients were reported. The present study was undertaken to evaluate the cell mediated immune status of patients with vitiligo using several in vitro and in vivo immune parameters. Thirty patients between the ages of 12 and 65 were observed at the Department of Dermatology of Ewha Womans University Hospital from Apri11981 through October 1981. Age matched 30 healthy persons comprised the control group. The results were summarized as follow: 1) The mean percentage of T lymphocytes in 30 vitiligo subjects and 30 control subjects were 55.3% and 67.4% respectively. There was a significant decrease of T lymphocytes in patients with vitiligo(p<0.05). 2) The percentage of subjects showing positive delayed hypersensitivity reactions to candidin, trichophytin and PPD were 33.3%, 43%, 50% respectively in 30 vitiligo patients and 60%, 75%, 80% respectively in 20 controls. A slight depression in delayed cutaneous hypersensitivity in gatients with vitiligo. (p<0.1). 3) The percentage of subjects showing positive sensitization with DNCB was 53% in 30 vitiligo patienta and 85% in 20 controls. A slight depression in DNCB sensitization was evident in vitiligo patients(p<0.1).

Housewife's eczema is not a specific disease but an inflammatory pattern of response to variety of stimuli: it is characterized by erythema, papules, vesicles, exudation, and scaling. Nickel is one of the most common causes of allergic contact dermatitis, particularly in women. The authors reported a case of housewife's eczema due to nickel sulfate occuring in a 30 year-old housewife for 3 years which was confirmed by patch test with 5% nickel sulfate and dimethyl glyoxime spot test on patients wedding ring and stainless bowels. Literature were reviewed briefly.

The authors observed a case of typical pemphigus foliaceus who was 26 year old male. The pemphigus foliaceus is a rare chronic vesicobullous skin disease which is a type of pemphigus, which has been reported rarely in Korea. This patient has been compained of formication of the face, trunk and upper arms since 7 monthes ago. The skin lesion revealed pea sized, flaccid bullar formation and dark bownish colored hyperpigmented macular eruptions with scattering distribution on the face, trunk, back and upper arms. This patient has experienced localized and generalized exfoliation during 7 rnonthes after onset, but he has not affected in general health condition. Biopsies were performed from the skin of the back, left wrist, and histopathologically the skin showed typical pemphigus foliaceus. So, diagnosis was confirmed by clinical appearance, histopathological finding and others. This patient was markedly imporved by prednisolone without immunesuppressant drugs, and antibiotics and antihistaminics etc.

Dupuytren's contracture is a idiopathic hypertrophy of palmar aponeurosis and consequent flexion deformity of distal palms and fingers. This patient is a 58-year-old man who has been suffering from diabetes mllitus since last 20 years. Skin lesion developed from one year ago. Skin lesion is a well defined, yellowish brown, nontender, firm, pea-sized nodule at distal palmar crease proximal to ring finger on both hands. On physical examination, he is within normal limit except skin lesion and flexion deformity on both hands. Skin biopsy on nodule revealed non-specific fibrosis. Literature was briefly reviewed.

Pityriasis lichenoides chronica is considered to be a benign disease. Erythematous yelIowieh scaly maeulea appear insidiously, chiefly on the sides of trunk, thighs and upper arms. Acanthosis nigricans is a rare cutaneous disorder with peak incidence in puberty characterized by hyperkeratosis and, dark pigmentation. We report a case of pityriasis lichenoides chronica assaciated with pseudoacanthosis nigricans in a 14 year-old obeae male patient who has bean sized erythematoua scaly papules on the trunk and extremities, velvety black brownish colored patchea on the neck and both axillary regions.

It is believed that the photopatch test is a valuable screening procedure for the determination of responsible antigenic substances in photoallergic contact dermatitis. But the technigues used for this procedure are cumbersome and require expensive equipment. In the present study, we adapted an easy and inexpensive photopatch test met- hod to our need. We report the results of this test method which was performed. in 21 patients with photodermatitis and 9 patients with polymorphic light eruption. 1. The UVB sensitivity determined by minimal erytherna dose (mean+-standard deviation) was I1618mW sec/cm in photodermatitis group, 108+ROmW sec/cm in polymorphic light eruption group and 126-+32mW-sec/cm in control group. But there was no significant difference among them (p>0. 05). 2. The reaction to UVA were negative in all groups. R. The photopatch test using IO potential photosensitizers revealed 12 positive responses in 9 patients; including 7 patients in photodermatitis group and 2 patients in polymorphic light eruption group. And the number of positive photopatch responses obtaied with each photosensitizer in RO patients with photodermatoses was 5 in chlorhexidine, 2 in paraaminobenzoic acid, musk ambrette and bithionol and 1 in chlorpromazine, respectively.

Verrucous hemangioma is congenital hemangioma, which is structural varients of capillary or cavernous hemangioma. And it is vascular malformation, in which reactive epidermal acanthosis, papillomatosis, hyperkeratosis develope secondarily. Though foreign anthors have reported some cases of this disease, it is rare hemangioma and it never has been reported in Korea. This 13 year-old, healthy female patient has erythematous patchs on her left knee at birth. It grew become coin to egg sized. Because of verrcous iuflammatory reaction of irregular verrucous surfaced plague, the lesion become necrotic thick crusty plague with severe offensive odor and patient complained of severe pain & motion limitation on her left knee. Urinalysis, C B C, chest PA were within normal limit. PPD test was negative. Lt. knee AP & lat. revealed. Marked destroyed soft tissue on anterior portion of Lt. knee and no bony pathological changes were demonstrable. Histopathologica.11y, hyperkeratosis, parakeratosis, acanthosis, papillomatosis in the epidermis and numerous capillary lumina, capillary dilatation, proliferation of endothelial cells and mild infiltration of inflammatory cells in the Dermis. And fibrosis in the Dermis & Subcutaneous tissue are seen.
