Nevus flammeus is benign but cosmetically devastating congenital vascular malformation whose past treatments have been marred by unacceptable complication or by unacceptable ineffectiveness. The argon laser is a therapeutic device which has been newly applied to this condition. Blue-green argon light is absorbed by the intraluminal red hemoglobin molecule, leading to the destruction of blood vessels. This study was undertaken to evaluate the therapeutic effect, to look for complications caused by the argon laser on nevus flammeus and to investigate the prognostic values of the color, the degree of blanching and the histological pattern of lesion after laser treatment. All patients were treated with Coherent Radiation Model No. 1,000 Laser with a spot size of 1mm diameter. The power range was 1.8W (irradiance of 229W/cm2), the pulse duration was 0.4 second and the repetition rate was 120 impulses per minute. The result was evaluated according to the criteria of Gilchrest(Table 1). Among the 109 patients who have been treated between November, 1981 and July, 1982 at the Department of Dermatology, Seoul National University Hospital, data from the 49 patients who could be followed up was evaluated and analyzed.

This study was undertaken to elucidate any quantitative abnormalities of T cells and T subsets(helper/inducer T cell: T cell and suppressor/cytotoxic. T cell; Tsc cell) in the peripheral blood and cutaneous lesion in patients with atopic dermatitis by using monoclonal antibodies, and to ascertain whether there are any relations bctwcen such immunologic abnormalities and the severity of the disease. Thirty seven patints(19 male, 18 female) were entered in this study, who vistited the Departement of Dermatology of Seoul National University Hospital frnrn February 1985 to November 1985. The control group comprised fifteen healthy children (8 male, 7 female). The peripheral blood samples of 30 patients and the skin biopsy specirnens of 29 patients were examinecl. Both were examined in 22 patients. The results showed that there was a quantitative abnormality in pcripheral blood Tsc cells in patients with atopic dermatitis and it could be related to the severity of the disease. The predominance of T cells seemed to be relatecl to the pathogenesis of atopic dematitis.

Dermographism is an exaggerated triple response of Lewis and appears as a lineat wheal with a flare at a site in which skin is briskIy stroked with a firm object. The etiology and pathogenesis of dermographism are uncertain but passive transfer tests are sometimes poeitive. The active serum factor has been characteiized as Ig E in some patients. In this experimental study, we tried passive transfer of dermographism with the sera of the patients with dermographism. Twelve dermographic patients' sera were tested to fourteen normal healthy persons and two asymptomatic dermographic persons, total number of thirty nine cases. Only two recipients were passively transferred but they showed positive responses to all sera tested, two and three respectively. This result suggests that not only serum factor but also recipient's factor(s) may be concerned in passive transfer of dermographism.

The term "osteoma cutis" is limited only to primary cutaneous ossification in which there is no evidence of Albrights hereditary osteodystrophy in either the patient or his farnily. We herein present a case of osteorna cutis in a 2-year-old male. He had had multiple hard plaques on the extremities since birth and had not had the evidences of Albrights hereditary osteodystrophy and signs of secondary cutaneous ossification such as trauma, injection, previous skin lesions and abnormal laboratory findings. The histopathologic findings revealed bony spicules with numerous osteocytes, cement lines, Haversian canals, osteoblasts and osteoclasts.

A 15-year-old female patient had malignant atrophic papulosis(Degos' disease) that affected the skin and probably intestinal tract. She had multiple erythematous papules with porcelain-white atrophic centers on the trunk and extremities. Also she suffered from intermittent nausea, vomiting and abdominal pain. She received appendectomy for abdominal pain 2 months ago. Histopathologic studies showed atrophic epidermis and necrobiotic dermis. There were endothelial thickening, fibrinoid necrosis of bload vessels, perivascular lymphocytic infiltation in the lower dermis. She was treatd with acetyl salicylic acid and dipyridamole, but there was no improvement.
