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.

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.

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.

Current concept of the pathogenesis of preeclampsia involves the generalized dysfunction of maternal vascular endothelial cells. Using ELISA (enzyme-linked immunosorbent assay) method, the fibronectin, as a marker of endothelial cell injury, was measured in the group of 35 cases of preeclampsia (mild; 15 and severe; 20 cases) and the control group of 21 cases of normal pregnancy. The clinical profiles, hematologic and renal function test results were compared and correlated with the levels of plasma fibronectin between two groups. The results obtained were as follows 1. The mean age between preeclampsia and control group was not different statistically, but gestational age, birth weight and maternal weight were different significantly between two groups. 2. Compared with normal control group, plasma levels of fibronectin were signifi- cantly elevated in preeclampsia group. As to the differential validity between two groups (control vs preeclampsia), using cutoff value of 380 mg/dl, sensitivity was 95.7 %, specificity was 90.5 %, predictive value was 93.8 %. As to the differential validity between mild and severe preeclampsia, using cutoff value of 742 mg/dl, sensitivity was 65.0 %, specificity was 73.3 %, predictive value was 76.5%. 3. As to the correlationship between plasma fibronectin levels and hematologic test results, uric acid and creatinine levels showed positive correlation in preeclampsia. Based upon these study results, plasma fibronectin could be a useful parameter for the differential diagnostic validity and grade of preeclampsia.

Granuloma gluteale infantum may be considered a complication oi the primary irritant type of diaper dermatitis and a modern disease due to the change in tae are of the napkin area. Most patients were infants who had worn plastic diapers and were treated with fluorinated topical corticasteroid cream for their diaper dermatitis. The lesions comorise one or several, soft and reddish brown or livid purple nodules on the napkin area. We report a typical case of granuloma gluteale infantum in a 13-month old female who had been treated with topical cortieosteroid crearn for her diaper derniat;lis. The granuloma regressed spontaneously after withdrawl of the topical corticosteroid and restricted use of the occlusive plastic diaper.

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.
