A Case of Childhood Dermatofibrosarcoma Protuberans / 대한피부과학회지

Dermatofibrosarcoma protuberans(DFSP) is a rare, distinctive cutsneous tumor originating in the dermis that appears as a raised uninodular or multinodular lesion on the trunk or the proximal extremities. In about 10% of the cases, DFSP arises in childhood and it is rarely evident already at birth. Histopathologically, DFSP shows the chsracteristic storiform and cartwheel patterns, with the fibroblasts arranged radially about a small central hub of fibrous tissue. We report herein a case of childhood DFSP in a 7-year-old boy.

Clinical Study and Recall Antigen Test in Seborrheic Dermatitis / 대한피부과학회지

We studied the age of onset, occupation, inducing or aggravating factors, distribution of skin lesions in 153 patients and recall antigen test in 15 patients of seborrheic dermatitis. The results were as follows : l. Seborrhic dermatitis occurred most frequently at the third decade and the number of patients was 1(0.7%) in the first decade, 41(26.8%) in the second decade, 58(37.9 %) in the third decade, 29(l9.0%) in the fourth decade, 12(7.8%) in the fifth decade, 5(3.3%) in the sixth decade, 4(2.6%) in the seventh decade, and 3(1.9%) in the eighth decade 2. There was family history of seborrheic dermatitis in 40 patients(26.1%) 3. Of the occupations, 48 patients(31.4%) were clerks or office workers, 42 patients (27.5%) were housewives, 23 patients(15.0%) were laborers or factory workers, ll patients(7.2%) were students, 9 patients(5.9%) were managers, and 6 patients(3.9%) were drivers. 4. Inducing or aggravating factors were emotional stress in 75 patrents(49.0%), seasonal change in 53 patients(34.6%), sunlight in 23 patients(15.0%), foods in 15 patients(9.8%), upper respiratory tract infection in 14 patients(9.2%), menstruation in 9 patients(5.9%), and drinking of slcohol in 9 patients(5.9%). 5. I,esions occurred on the scalp in 128 patients(83.7%), on the face in 115 patients (75.2,l6), on the neck in 42 patients(27.5%), on the trunk in 29 patients(19.096), on the intertriginous areas in 12 patients(7.8%), and on the extremities in 6 patients(3.996), 6. The intensity and rate of delayed hypersensitivity reaction in 15 patients of seborrhic dermatitis(1.62+/-0.92mm, 28.67+26.4596) were not significantly decreased than those of control group(1.99+1.08mm, 39.23+/-22.34%) (p>0.05). Anergy and hypoergy were found in 10 patients(6796) with seborrheic dermatitis in contrast to 6 persons(4096) in control group.

A Case of Cutis Laxa / 대한피부과학회지

We experienced a case of cutis laxa in a 17-year-old man. The skin showed diminished elasticity with loose folds, wrinkling, and sagging on the abdomen, lower back, and both inner thighs. There was no history of any inflammatory skit diseases prior to the appearance of the wrinkling. Family history revealed to be negative for the skin diseases showing wrinkling and laxity. The biopsy specimen from the skin of the abdomen showed shortened, fragmented elastic fibers in the dermis. The serum copper level was normal(92 ug/dl).
