This study was performed in the Korean recruits to determine the prevalence and the sites of predilection of the nevi involving melanocytes. The results were summarized as follows; 1) 411 of 2311(17. 7%) recruits examined were found to have nevus spilus, most prevalent in the trunk. The lesions were usually solitary but occasionally two or three lesions were found in a single individual. The prevalence of speckled lentiginous nevus was 0.49%,(2l/4247). The site of prevalence of progressive cribriform and zosteriform hyperpigmentation was 0. 80% (34/4247). The lesions were most commonly observed in the lower trunk and upper thighs. 4) The prevalence of Becker's nevus was 0.45%(19/4247). The lesions were most commonly observed in the shoulder and its surrounding areas. 5) Persistent Mongolian spot were observed in 2. 73% (63/2311). The proportion of extrasacral spots to sacral spots was increased to almost half of the entire spots. 6) Blue nevi were observed in 0. 48M (11/2311), most frequently in the sacral area.

Reactive perforating collagenosis, first described by Mehregan et al in ]967, is a skin disorder characterized by transepidermal eliniination of altered collagen fibers. This rare disease appears as recurrent, umbilicated, crusted papules in response to minor trauma. We report here a case of reactive perforating collagenosis in a 21-year-old man. Examination of the skin revealed a number of centrally umbilicated, asymptomatic papules filled with keratotic plugs in various development and regression. The lesions were distributed on the dorsa of the hands, face, and neck. The biopsy spccimen showed a few of thin bundles of collagen which v ere extruded from the dermis through the atrophic epidermis and the turinels within the epidermis, reaching the buttom of the plug.

We report a case of acral persistent papular mucinosis in a 5 year-old female with multiple papules on both dorsa of the hands, wrists and forearms. Examination of a biopsy specimen showed a domeshaped lesion in the dermis composed of spindle-shaped fibrobla,sts and widely spaced collagen fibers. These spaces were filled with mucinous material, as demonstrated by positive staining with aleian blue at pH 2.5 and pH 0.5.

Progressive cribriform and zosteriform hyperpigmentaion (PCZP) is a pigmentary disorder of the skin which was first described by Rower et al in 1978. The disorder is characterized clinically by uniformalyptan cribriform macular pigmentation in a zosteriform distibution and histopathologically by absence of nevus cells and increased melanin in the basal cells. The authors have experienced a case of PCZP in 21 year old Korean man which we believe is the first documented case in Korea. The patient noted light brown macules on his left inguinal area at the age of 17 which has gradually extended to become cribriform macular pigmentation in a zosteriform distribution. Histopathologic examination of the lesion showed an increase in basal melanin pigmentation. No nevus cells were present.

Among the patients visting Department of Dermatology, Chungman National University, 58 cases had various side effects due to the malpractice of skin disorders. We analysed these 58 cases and the results can be summerized as follows ; 1. 37 cases(64%) were in the second and third decades and 11 cases(19%) were under 19 years-old. 2. Drug medication from pharmacy was the most common(79%), and then local clinics(12%), herb clinics(9%) in decreasing orders. 3. In the route of administration, oral ingestion(38%) was the most common, and 47 cases (81%) were medicated with adrenocorticoids. 4. In motivation to the visit, 31 cases(53%)were by advice, 15 cases by advertizement and 12 cases (21%) by themselves. 5. Acne and psoriasis were about a half of pre-existing skin diseases. 6. Side effects due to malpractice may be divided into 5 items : systemic side effects due to adrenocorticoids (59%), aggravation of pre-existing skin diseases (22%), topical side effects due to adrenocorticoids (10%), chemical irritation and burn (7%), and mercury intoxication (2%) in decreasing orders.

The formation of spontaneous rosettes between human lymphocytes and sheep erythro ytes under suitable conditions is a constant feature of T-lymphocytes. Recently. It has been demonstrated in the mouse, rat, guinea pig and in man that a certain proportion of peripheral blood lymphocytes has the property to bind autolognus erythrocytes in vitro. These lymphocytes are called auiologous rosette forming cells(ARFC). Although there are several reports on human ARFC. the results are not in accordance. The present study was undertaken to demonstrate the autologous rosette forming property of human peripheral blood lymphocytes, and to enumerate the percentage of ARFC in different sex and age guoups. Fifty healthy persons entered this study between Martch and September. 1980. at the Department of Dermatolgy, Seoul National Universty Hospital. The method of quantitation of AREC was s sight modification of that of Lambermont et al(1977). The results were as follows.

The nipple involvement in atopic dermatitis is not mentioned in currently available major textbooks of dermatology. Recently, Hanifin and Rajka indicated that the nipple involvement is a specific indicator of atopic dermatitis though it is quite rare. The authors described 3 cases of atopic dermatitis with nipple involvement among 224 cases of atopic dermatitis seen over 2 year period at the Special Clinic for Atoipc Dermatitis. The nipple lesions responded to topical steroid quite satisfactorily.

The close similarity of acrokeratosis verruciformis(AKV) to the acral lesions of Dariers disease is well known. However, the exact relationship between the two disorders has not been satisfactorily resolved. A case of Dariers disease associated with guttate leukoderma and AKV is presented. The patient was a 17-year-old male who had dark cursted papules on the neck and lower abdomen, flat-topped keratotic papules on the dorsal surface of hoth hands, and white macules disseminated on the trunk and lower extremities of 7 years duration. The histopathologic examination of the lesion on the lower abdomen revealed parakeratotic plugs, corps ronds, and suprabasal clefts. The lesion on the dorsum of the hand showed compact hyperkeratosis, acanthosis, and papillomatosis with the pattern of church spires. The leukodermic lesion revealed decreased melanin content in the epidermal cells.
