A Case of Congenital Triangular Alopecia in Infancy / 대한피부과학회지

Congenital triangular alopecia is an uncommon nonscarring form of alopecia. It presents with isolated alopecic patch at the frontotemporal area of the scalp. Although previously considered congenital, this condition usually is discovered after 2 years of age and, more recently, is thought to be acquired. We report a case of congenital triangular alopecia in a 12 month old female who had the lesion since birth.

A Case of Acantholytic Dyskeratotic Epidermal Nevus / 대한피부과학회지

Acantholytic dyskeratosis is a regular histologic feature in Darier's disease, transient acantholytic dermatosis and warty dyskeratoma. It is also occasionally observed as an incidental histological finding in linear epidermal nevus. We report a case of acantholytic dyskeratotic epidermal nevus in an 11-month-old boy. The patient showed unilateral, brown colored verrucous plaque on the right shin. Histological finding showed hyperkeratosis, irregular acanthosis & focal acantholytic dyskeratosis.

A Cases of Erythema Elevatum Diutinum / 대한피부과학회지

Erythema elevatum diutinum(EED) is a rare chronic skin disease characterized by red, purple, and yellowish papules, plaques, and nodules that are usually distributed acrally and symmetrically over extensor surface. It is characterized histologically by a leukocytoclastic vasculitis. Although no treatment has shown a complete response, dapsone is reported to be effective to EED. We report a rare severe case of EED with good response to dapsone treatment.

A Case of Primary Cutaneous CD 30 Positive Large Cell Lymphoma Showing Spontaneous Complete Regression / 대한피부과학회지

The phenomenon of spontaneous regression, which is one of the characteristics of primary cutaneous CD 30 positive large cell lymphoma, has been observed in approximately one fourth of patients. However, complete regression is far less frequent than partial regression. We report a case of primary cutaneous CD 30 positive large cell lymphoma in a 53-year-old male patient who showed spontaneous complete regression without any treatment.

The Environment and Lifestyles of Atopic Dermatitis Patients / 대한피부과학회지

BACKGROUND: Atopic dermatitis is one of the most common inflammatory skin diseases in children, affecting 5% to 15% of children. Its prevalence has increased gradually over the last three decades. Although a genetic predisposition to the disease has been implicated, environmental factors play a crucial role in the disease expression. OBJECTIVE: This study was performed in order to elucidate the environment and lifestyles of atopic dermatitis by questionnare. METHODS: Investigation of this study was carried out among 70 atopic dermatitis patients and 70 normal control subjects. We asked them to fill up all the questionnaires in relation to the environment and lifestyles of atopic dermatitis patients. RESULTS: 1) Maternal educational status of atopic dermatitis patients was higher than that of normal control group(p<0.05). 2) Fifty-one(72.9%) of 70 patients with atopic dermatitis dwelt in apartment and only two patients with atopic dermatitis had pets. 3) There were no statistical differences in type and duration of milk feeding and preference of foods. 4) Fourty-seven(67.1%) of 70 patients with atopic dermatitis took a bath only one or two times in a week. CONCLUSION: The results of this study could be some help to the doctors who examine atopic dermatitis patients.

A Case of Bilateral Lichen Aureus with Good Response to PUVA Therapy / 대한피부과학회지

Lichen aureus is regarded as an uncommon variant of the pigmented purpuric dermatosis and resistant to treatment. Recently several authors reported the PUVA therapy to be effective in the pigmented purpuric dermatosis, but there was no report that the PUVA therapy was tried to the lichen aureus. We tried topical PUVA therapy on a 54-year-old male with bilateral lichen aureus. After 23 times of topical PUVA therapy, the lesion improved markedly. This report may provide a new method of treatment for lichen aureus.

Fixed Drug Eruption Caused by Piroxicam / 대한피부과학회지

A fixed drug eruption is a cutaneous reaction caused by various drugs, which include phenazone derivatives, barbiturates, sulfonamides, tetracyclines and phenolphthaleins. An eruption caused by piroxicam is very rare and there have been no previous reports in Korea. A 49-year-old woman was seen with mutiple erythematous patches and some bullae that appeared after oral administration of piroxicam. The patient had had two similar episodes after oral administration of piroxicam. We performed patch test with piroxicam and could confirm a fixed drug eruption caused by this durg.

A Case of Papillary Eccrine Adenoma

Papillary eccrine adenoma is a rare sweat gland tumor with a characteristic histopathological appearance and has a benign clinical course. Five cases were reported in Korea since a report by Song et al. in 1988. We report a case of papillary eccrine adenoma in a 38-year-old male who had a firm, dark brown nodule on the medial surface of the left thigh. Microscopically, the tumor was composed of multiple dilated ducts lined by two or more layers of epithelial cells and the luminal cells showed papillary projections into the lumen in some tubules. Immunoperoxidase staining was positive for CEA, S-100, and EMA. We excised the lesion completely and no evidence of recurrence was observed for 6 months.

A Case of Chronic Actinic Dermatitis Showing Contact Allergy / 대한피부과학회지

Chronic actinic dermatitis is an uncommon, persistent, light induced eruption occurring mostly on exposed skin. It is eczematous or pseudolymphomatous in nature, probably representing delayed type hypersensitivity to endogerious photoallergens. It usually worsens in summer and affects elderly men. A 72-old-male was presented with a 14 month history of pruritic skin lesions. They were composed of waxy thickened scaly plaques of the face and dorsa of the hands, and depigmented patches of the neck, which worsened when exposed to sun light. We performed photo test and photopatch test. MED of UVA was lowered and the patch and photopatch test revealed only contact sensitivity to Balsam of Peru, perfume mix and fragrance mix. A biopsy specimen showed hyperkeratosis and spongiosis of the epidermis and perivascular lymphocytic and many eosinophilic infiltrations of the dermis. The patient was treated with systemic and topical corticosteroids with marked improvement.

Angiokeratoma of the Vulva / 대한피부과학회지

Angiokeratoma of the vulva is a relatively rare, benign condition that usually presents as single or a few isolated papules mainly on the labia majora. It is histologically identical to angiokeratoma of the scrotum. A 50-year-old woman presented with a one year history of nonpruritic lesions on the vulva. Her skin lesions used to bleed vith subtle trauma. Several dark purplish papules, ranging in diameter from 3 to 5mm, were noticed on both labia majora. A biopsy confirmed the diagnosis of angiokeratoma. A simple electrodesiccation of all lesions was performed under local anesthesia. The patient has remained asymptomatic nd without recurrence for the follow-up period of 10 months without any recurrence.
