1.The treatment of bengin cutaneous tumors with carbon dioxide laser.
Korean Journal of Dermatology 1993;31(4):502-507
BACKGROUND: CO laser emiis energy in the mid portion of the infrared spectrum at a wavelengt,h of 10,600nm. The CO laser is the workhorse laser in the treatment of cuianeous disease. With water as the chromophore(light-absorbing compound), CO laser light is highy absorbed in biologic tissue. Human body tissue comprises between 75% to 90% of water. The CO laser is superficially absorbed by tissue water, with little scatter, limiting penetration into the skin to less than 0.1 mm. The beam can be delivered with a large spot size and low power density(defocus mode) or focused tightly with great power density(focused mode). AS A RESULT: the CO laser may be used both to vaporize and to cut tissue while coagulating blood vessels, providing a relatively bloodless su gical field. OBJECTIVE: The purpose of this study was to evaluate the therapeutie effect of the CO laser on benign cutaneous tumors. MEHTODS: 114 cases of benign cutaneous tumors treated with the CO laser between October 1987 and September 1992 were subjected to detailed analysis, The CO later is Pizer Laser system(U.S.A., Ca) Model 20-C CO. The laser produces power output that ranges from 0 to 25 W of continuous wave. Spot size is variable, between 0.3mm and 2mm. RESULTS: 1. Angiofibromas and seborcheic keratoses showed very good response(95.3%, 92.8% ). 2. Syringomas showed a good esponse(82.8%). 3. Epidermal nevus and trichovpitheliomas showed a fair response(58.5%, 60%). 4. There were hypertrophic scars(10.5%) and transient hypopigmentation. CONCLUSION: The Co laser was a very effective modality for the treatment of benign cutaneous tumors such as angiofibromas, seborrheic keratosis and syringomas.

2.Molluscum contagiosum occuring in an epidermal cyst.
Korean Journal of Dermatology 1992;30(6):917-919
We report a case of molluscum contagiosum occurring in an epidermal cyst. A-38-year old male patient had the lision which was a 1.2 x 1cm sized, elevated, round nodule on the right cheek. Histology showed true epidermal cyst containing molluscum bodies throughout the cyst wall and laminated keratotic material within the cyst itself.

3.A Case of Allergic Contact Dermatitis to Ribavirin.

Annals of Dermatology 1993;5(1):44-46
Allergic contact dermatitis to topical agents mostly results from vehicles and preservatives and rarely from the active ingredients. Ribavirin, an active ingredient of Viramid® cream, is a synthetic nucleoside derivative with broad spectrum activity against a wide variety of DNA and RNA viruses. We report an 18-year-old woman, who had a perioral edematous patch with exudative crusts after topical application of Viramid® cream (nsung pharmaceutical Co., Korea) for the treatment of herpes labiahs. A patch test showed that the sensitizer was ribavirin, the active ingredient of the antiviral agent, Viramid® cream.

Congenital self-healing reticulohistiocytosis (CSHRH) typically presents at birth or in the first few weeks of life as a widespread eruption of cutaneous red-brown papulonodules that resolve spontaneously without involvement of other organs. While multiple lesions are common, a solitary lesion is rare. We describe a solitary type of CSHRH in a full-term, male neonate. He had an erythematous papule with a yellowish crust on the left heel without any systemic symptoms. Four weeks later, the skin lesion had disappeared spontaneously.

BACKGROUND: Recurrent recalcitrant warts are likely to increase gradually, and require more aggressive and effective treatment for remedy. According to recent foreign research materials and literature, aminolevulinic acid photodynamic therapy (ALA-PDT) is reported to prove to show high curative performances, but there has been little relevant research in Korea to date. OBJECTIVE: This study will evaluate the efficiency and side effects of ALA-PDL and PDL in treating recalcitrant viral warts. METHODS: 120 warts from 44 people were selected and sorted by their locations such as hand, foot, and periungual area, and then randomly divided into 2 groups: ALA-PDL group and PDL group. The ALA-PDL group used 20% 5-ALA as a photosensitizer, and PDL for the light-source, the other group used PDL. The setting of PDL being used in both groups is as follows: wavelength of 585 nm, spot size of 7 mm, and energy density of 7.0~10 J/cm2. RESULTS: After 3 treatment sessions, the complete clearance of ALA-PDL and PDL groups was 44/59 (74.6%), 18/61 (29.5%), partial clearance-good was 8/59 (13.6%), 20/61 (32.8%), partial clearance-poor was 7/59 (11.9%), 21/61 (34.4%) and no response was 0/59 (0%), 2/61 (3.3%). The average treatment sessions were 2.32 and 2.97 times. ALA-PDL group showed pain in 27/59 (45.8%) for the first and second treatment sessions, and postinflammatory hyperpigmentation (PIH) in 11/59 (18.6%). The PDL group showed only PIH in 3/61 (4.9%). CONCLUSION: PDT is an efficient treatment modality in recalcitrant viral warts. Especially in the case of periungual warts, it is very safe and cosmetically satisfactory without serious side effects such as nail deformity.

Eosinophilic cellulitis is a rare recurrent inflammatory dermatosis, characterized clinically by well-circumscribed erythematous plaques. The histopathologic features of the lesions are dermal edema, infiltration of eosinophils and development of 'flame figures' in the dermis. A 64-year-old female presented pruritic erythematous plaques, with associated bullae, on her right hand and wrist. Histopathologic examination showed infiltration of eosinophils and characteristic flame figures in the dermis. The clinical presentation and histopathologic alterations are consistent with the diagnosis of eosinophilic cellulitis. Herein, we report a case of bullous eosinophilic cellulitis which is an uncommon variant of eosinophilc cellulitis.

Korean Journal of Dermatology 2007;45(11):1230-1232
Reactive perforating collagenosis is one of a range of essential perforating disorders and is characterized by the transepithelial elimination of altered collagen. Two types have been recognized: the inherited, or childhood form and the acquired, or adult form. Acquired reactive perforating collagenosis is associated with systemic diseases, especially diabetes mellitus and/or renal failure. We report that a low-dose allopurinol showed dramatic effects on acquired reactive perforating collagenosis, which was associated with hypothyroidism and chronic renal failure caused by diabetic nephropathy.
