A group of chemicals that have proved to be frequent causes of allergic contact dermatitis from applied ingredients of the vehicle. Fisher (1971) testing with a vehicle tray of 15 chemicals in 100 patients with allergic contact dermatitis due to topically administered medications found 30 positive patch test reactions of patients and reported that most important sensitiiing chemicals are Ethylenediamine, Lanolin, Farabens, Phenylmercuric acid, and. propylene glycol monostearate. These chemicals have been recognized as such common sensitizers that they are nonincluded. in the standard patch test series by many countries. From the standpoint of allergenicity of topical preparations including topical medicaments and cosmetics, prevention and diagnostic procedures of dermatitis should be investigated extensively through the patch test studies. But, in our country, there has only a few investigation conceming the dermatitis from vehicle, particularly the medicaments and cosmetics. Therefore, author has tried to establish the vehicle tray fitted to our country according to the basic consideration used with the vehicle patch test tray of Fisher. 100 patients suspected of having allergic contct dermatitis due to topical medication or cosmetics were patch tested with a group of chemicals composed of substances commonly found in vehicles of current topical medications or cosmetics. There were many significant reactions to Ethylenediamine, Paraben, Lanolin, Sodium lauryl sulfate, Polyethylene glycol and Turpentine which play a significant role as solubilzer, antioxidants, emulsifieis, exirpients, preservatives, stabilizers, and surfactants. Author proposed that a group of chemicals should be patch tested on patients of allergic contact dermatitis for the establishmc,nt and development of the hypoallergenic topical medicaments or cosmetics.

A case of Toxic epidermal necrolysis in 19 th years old man is presented. This patient has been suffering from erythematous patches and bullae over entire body including vesicles, erosions, and fissures on both lips since 2 days ago after taking some drugs (analgetics, aspirin, chloramphenicol, sulfisoxazole, erythromycine.) for treatment of tonsillitis. Furthermore, it is very difficult for us to say why the disease has occured. Toxic Epidermal Necrolysis (TEN) by talking drugs or Staphylococcal Scalded Skin Syndrpme (4S) by staphylococcus aurues because staphylococcus aureus was found on bacteriai culture from his throat swab. He was treated with corticosteroid, antibiotics and fluids for 20 days with good result. Literature was briefly reviewed.

Familial benign chronic pemphigus is characterized by a recurrent eruption of plaques of closely grouped vesicles that most frequently occurs about the neck, axilla and groin, singly or in combination with similar lesions in the intertriginous area. A 27-year-old male has had recurrent vesicles, fissures, maceration and crust formation in inguinal and perianal area for 3 yeare. The lesion manifested circinated form of vesicles, fissured and scaly patches over the inguinal, scrotal and perianal area. There were actively inflammatory border, resembling tinea cruris in the inguinal area. Authors diagnosed with clinical symptoms, laboratory examinations, and light and electron microscopic examination.

Erythema dyschromicum perstans is a cutaneous pigmentary dermatosis of unknown etiology chararcterizd by asymptomatic macules of an ashy gray color which was first presented by Ramirez. We reported a case of Erythema dyschromicum perstans in 57 year old female patient. The skin lesion were characterized by the presence of discreated or confluented bluish-gray colored pigrnentation on the lateral surface of hoth upper extremities. Histologically, the lesion showed hydropic degeneration of the epidermis witb in continence of pigmcnt and an apperence of malanin-hearing macrophages in upper dermis which are compatible with Erythema dyschromicum perstans.

Urticaria pigmentosa is a manifestation of mastocytosis characterized by persistent pigmented cutaneous lesions of various size that tend to urticate upon mechanical or chemical irritation, The disease is most common in ehildren and skin lesions after appear within 1 or 2 months of birth. Urticaria pigmentosa in children begins with disseminated eruption (buIlou type) or with a solitary tumor or nodule(solitary type). One case. of solitary type and one case of bullous type are reported in this paper. The one case is a solitary type of urticaria pigmentosa in 1 1/2 years old male who had dark brownish pigmented nodule(2.5 1cm) on right hack since 1 year ago. Tie other is a bullous type of urticaria pigmentousa in 6 months old male who had generalizcd. bulla, hemorragic bulla with crust & millium since 4 months ago. Dignosis was confirmed by histologic findings in which showed infiltration of mast cells in upper nr entire dermis arui rnetachromatic granules in mast cell on toluidine blue stain. Literature were reviewed briefly.

Epidermolysis Bullosa Simplex is characterized by autosomal dominant rnheritance, and chronic noninflammatory conditions in which the clinical lesions, erosion, blisters usually result from relatively minor mechanical trauma to the skin, especially joints of hands, elbows, knees, and feet and other sites subject to repeated trauma The lesiona are present or appeared after a few days after birth or shortly after especialy of the lower legs or feet, and not involved at naiIs or mucous membranes. Though infection is not common on the feet or hands, even infected lesions generally heal with out scarring. 2 cases of Epidermolysis bullosa simplex were experienced, the one was 5 month old male baby who had fresh vesiculobullous, hemorrhagic bulla, crusts, exfoliation, no nail dystrophy, since a few days after birth. The another was 5 month old female baby, who had pea sized tense bulla, and exfoliations on the hands and feet. Diagnosis confirmed by clinical features and histological findings. Literature were reviewed in comparison with mechanobulIous disease.

Multiple lentigines syndrome is characterized by the presence of numerous dark brown macules on the skin but not mucous surfaces and known also by the mnemvnic "LEOPARD syndrome" are, besides the lentigines, electrocardiographic conduction defect, ocular hypertelorism, pulmonary stenosis, abnormalities of the genitalia consisting of gonadal or ovarian hypoplasia, retardation of growth, deafness and inherited by autosomal dominant trait. We experienced a case of multipIe lentigine syrrdrome in 20-year old woman. She had numerous pinhead to pea sized, dark brownish macules on the entire body skin a,nd had no associated anomalies of other organ. On laboratory examinations including the CBC, urinalysis., chest X-ray, EKG; EEG, Hormone assay was all normal except for the slight anemic finding. On histologic examina,tion of biopsied macular skin showed a slight elongation of rete ri.dges, an increase in the concentration of melanocyte in the basal layer and mild inflammatory infiltration in the upper dermis. Treatment was done by cryotherapy on the face with marked improvement.

Demodicidosis is caused by the enormous infestation of 400 micron sized demodex folliculorum which normally exist, though in small number, in pilosebaceous unit. Its characteristic clinical feature is erythema and erythematous indurated papulopustular eruptions combined with itching and buming sensation. Microscopic examination of indurated pustule always reveals demodex folliculorum. Many authors have reported that demodicidosis aggravated by avoidance of using soap, long-term use of cosmetic cream, especially cold cream, topical or systemic use of corticosteroid. Our patiednts were housewives of 46,39, and 42 years old and presented characteristic clinical featurss and skin lesions by topical application of corsicosteroid for 1~2 years and were diagnosed as steroid acne. But simple microscopic examination reveled demodex folliculorum. We treated them with 5% sulfur lintment and soap and water cleansing of face with remarkable clinical improvement.

The solitary type of Koratoacanthoma is a common, rapidly growing, benign tumor with a natural history of spontaneous involution which was first described by Hutchinson in 1889. It was well known that this Keratoacanthoma is close resemblence to squamous cell carcinoma clinicallt & histopathology. The etiology of Kertoacanthoma is ucertain but it have been associated with many exogenous factors, including sun exposure, occupational exposure to heat and trauma, and tar and with autoimmune etiology and viral infection. We experienced 2 cases of soitary type of Keratoacantoma with typical clinical and histopathologic findings which presented on the pubic area and forehead but had no predisposing factors of Keratoacanthoma. The one was 66-year-old woman who had been a history of proritic, rapidly growing tumor on Mons Pubis since about 6 months ago. The another one was 40 year-old male who had been a history of asymromatic, growing tomor on forehead since about 3 months ago. In the H-E stained sections, there were horn filled invagination, dyskeratotic cell, horn pearl in the epidermis and an inflammatory infiltration in dermis. Diagnosis was cinfirmedby the clinical and histopatholigical pictures. The former was treated by electrocautery after simple excision and the latter by curretage and electrodesiccation.

Epidermolysis bullosa Dystrophica is rare, chronic non-mflammatory mechanobullous disease of hereditary trait, which easily produces bulIa by minor trauma or spontaneousIy. The lesions usually appears from birth or in infant involving especially lower leg, hand, foot and lea,ds to erosive, hemorrhagic bulla, secondary infection, pruritus and scar formation and sometimes deformity of nails and cicatrical alopecia. It sometimes involves oral mucosa, esophagus, eye, tooth, bone, respiratory system, anus and vagina. This disease has rare tendency for carcinogenesis from cicatrical Iesions. These manifestations are more severe in recessive type than in dominant type. We had observed 5 cases of EBD at Ewha Womans University Hospital from Sept. 1975. to Jul. 1976. Among 5 cases, 4 cases occurred from birth, 1 case occurred at age l. Skin lesivns were hand, foot, knee area in all 5 cases. Head, face were involved in 2 cases. Arm, leg, trunk, buttock were involved in 3 cases. In skin manifestations, bulla, erosive bulla, secondary infection, scar formation, pruritus, nail deformity, positive Nikolsky sign were observed in all 5 cases. Hemorrhagic bulla, miliaria. were presented, in 1 case, alopecia in 2 cases. Aggrevated season were summer in 4 cases, spring in 1 case, HistologicalIy, microscopic observation, after H@-E stain, revealed hyperkeratosis in 3 cases, acanthosis in 2 cases, partial atrophy in 1 case, partial ulcer in 1 case, snbepidermal bulla in 5 cases, chronic nonspecific inflamma- tory cell infiltration of upper dermis in 3 cases, fibrosis of lower dermis in 1 case.
