Oak moss is a lichen extract obtained from Evernia prunastri and Pseudovernia furfuracea. It is the potent,ial allergen in contact dermatitis to perfumes. Sensitivity to oak moss has been atributed mainly to atranorin, evernic acid, usnic acid and fumarprotocetraric acid. We report a 44-year-old female patient presenting with features of contact dermatitis due to oak moss in perfumes. Patch test results revealed positive reactions to fragrance mix, oak moss, atranorin and evernic acid.

We report a patient with a cutis laxa-like, generalized PXE without systemic involvement. A 28-year-old woman had loose, pendulous skin of the neck, axillae, thighs, trunk and body folds which resulted in a prematurely aged appearance. She had no family history of related diseases. Histological examination showed considerable accumulations of swollen and irregularly clumped fibers in the middle and lower dermis and von Kossa s stain revealed calcium deposits along the altered elastic fibers.

Increased melanin pigmentation following ultraviolet irradiat.ion is due to increasing tyrosinase activity and multiplicatian of functioning melanocytes. After UV-irradiation, the size of melanocytes increases, and melanocyte dendrites elongatc, and branch. In this experiment, we induced the activation of melanocyts in the epidermis of C57BL black mice by ultraviolet-B(UVB) irradiation and observcd ihe effect of azelaic acid and retinoic acid on the UVB activated epidermal melanocytes. Sixty C57BL black mice were irradiated by UVB 100mJ/cm daily for 10 days, and then azeiaic acid and retinoic acid were topically applied daily for 7 weeks. For the estimation of morphologic change of epidermal melanocytes, light microscopic observation with split DOPA stain was performed at the end of the 1st, 3rd, 5th and 7th week of topical application. The results are summerized as follows : 1. The number, size and circumference of DOPA-positive epidermal melanocytes were significantly decreased in 20% azelaic acid applied group and 30% azelaic acid and 0.05% retinoic acid applied group. 2. In 20% azelaic;i.cid and 0.05% retinoic acid applied group, the number, size and circumference of DOPA-positive epidermal melanocytes were nore significantly decreased than in 20% azelaic acid applied group. In summary, the present study suggets that azelaic acid act as a depigmenting agent on epidermal melanocyte; and such depigmenting effect of azelaic acid was increased by addition of retinoic acid.

A case of "Follicular Occlusion Triad" associated with acne conglobata, hidradenitis suppurativa and perifolliculitis capitis abscedens et suffodiens in 40-year-old male patient is presented with brief review of literature. Widespread acne occured on the face k upper back at the age of 16. Several years later, firm & tender erythematous poorly demarcated nodules developed on the back, buttock and axilla. Also, erythematous nodules developed on temporooccipital area of the scalp. Thereafter, the skin lesions become fluctuant cystic. Some of the skin lesions healed leaving severe hypertrophic scars, and purulent materials expressed from some of persistent lesions. The patient was trested with systemic 13-cis-retinoic acid, antibiotics, corticosteroids injection and incision & drainage with considerable improvement.

BACKGROUND: In tinea pedis, the response of treatment and prognosis are different according to clinical types. Positivity in KOH mount and causative agent in culture are also different. OBJECTIVE: Our purpose was to evaluate the clinical characteristics and mycologic findings of tinea pedis according to the clinical type. METHODS: A clinical and mycological study was conducted with 97 cases of tinea pedis among out patients examined for 7 months from June 1994 to December 1994 at Yeungnam University Hospital and Catholic Skin Clizic, Taegu, Korea. RESULTS: 1. Age distribution showed patients in their fourth decade to be most common. The ratio of male to female was 1.2: 1. The distribution of patients by clinical type was interdigital type, interdigital combined with hyperkeratotic type, interdigital combined with vesicular type, hyperkeratotic type, and hyperkeratotic combined with vesicular type, in descending order. One to five years was the most comrrion duration of tinea pedis. Duration of tinea pedis was the shortest in the vesicular type, otherwis was longer in hyperkeratotic type. Rate of family history of tinea pedis was 54.6%. The larger the size of family was, the higher the positivity in family history. The rate of coexistent dermatiophytosis with tinea pedis was 39.1%, and tinea unguium was the most common one. 2. The isolated dermatophytis were T. rubrum, 90.7%, T. mentagrophytes, 7.2%, and T. rubrum rnixed with T. mentagrophytes, 2.1%. T. rubrum showed an even distribution in all clinical types of tinea pedis whereas T. mentanophytes was isolated only in the interdigital type, vesicular type, and interdigital combined with vesicular type. T. rubrum mixed with T. mentagrophytes was isolated in the interdigital combine with vesicular type. Distribution of dermatophytes was relatively even arnong the age groups. T. rubrum showed a relatively even distribution in duration of tinea pedis, but T. mentagrophytes was isolated in tinea pedis with shorter duration.

Angiosarcoma is a rare malignant vascular tumor of endothelial cell origin, Cutaneous angiosarcoma usually occurs on the scalp and face of the elderly and most frequently in the sixth and seventh decade. We presented a case of angicisarcoma in a 70 year old woman. The patient had a well-demarcated, 3 x 3cm sized, dark brownish-colored, ulcerative nodule on the vertex with hemorrhagic bulla on the right. temporal scalp. Histopathologic examination of the nodule showed a well differentiated tumor with irregular anastomosing scular channels lined by atypical endothelial cells in the dermis and subcutaneous fat. Immunohistochenlical study for factorVlll-related antigen was partially positive in tumor channels. She was treated by wide surgical excision but she expired 5 months after discharge from the hospital.
