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.

BACKGROUND: Tinea faciale usually has been classified as tinea corgoris. Recently it has often been classified as a seperate disease recently because of its various clinicel pesentations. OBJECTIVE: Our purpose was to evaluate the clinical characteristics and mycological findings of tinea faciale, METHODS: Clinieal and mycological study was done with 42 eases of tinea faciale among out-patients examined for eight years from January 1985 to December 1992 at Yeungnam University Hospital, Taegu, Korea. RESULTS & CONCLUSION: 1. The average of annual distribution of patients was five and there a as no significant difference according to year. The age distribution of patients was highest under age 10(33.4%). The ratio of male to female patient was 3.1: 1. Monthly or seasonal distribution if patients was not significantly different. 2. Of 42 cases, causative organisms were isolated in 31 cases. They are Trichophyton(T.) rubrum in 19 cases (61.3%), Microsporum(M.) canis in 6 cases (19.4%), T. mentcgrophytes in 5 cases (16.1%) and M. gypseum in 1 case(3.7%) in tbe order of decreasing frequncd M. canis was the main causative organisrn in children under age 10. In the age group after 10, T. rubrum was predominated. T. rubrum infection was most frequently seen in spring, T. mentagrphates infection was seen more in winter and M. canis infectior in autumn. 3. Classic annular types were seen most frequently in the cases caused by T. rubrum and T. mentagrophytes. Papular types were seen most commonly in the case caused by M. canis. Multiple facial lesions were seen in T. rubrum infection (2 cases) and Of canis infection (1 case). Tinea faciale simulated several other dermatoses. These were contact, dermatitis, lupus erythematosus, photosensitive dermatosis, rosacea, granuloma annulare and acne. Of these, tinea faciale simulated contact dermatitis most frequently. Coexisting fungal infections were found in 7 patients and tinea corporis was most frequently present. Topical antifungsl agent was tried alone in 22 cases, and topical and systemic antifungal agent were combined in 20 cases.

Linear porokeratosis is a rare variant of porokeratosis and usually occurs in childhood. A 37-year-old female is presented with linear porokeratosis on the posterior aspeet of the right lower extremity exhibiting the classical histopathologic criteria of the disease. Treatment with an oral etretinate resulted in a remission of the lesions.
