Fragrance contact dermatitis in Korea: a joint study.

The purpose of this study is to determine the frequency of responses to selected fragrances in patients with suspected fragrance allergy and to evaluate the risk factors. 9 dermatology departments of university hospitals have participated in this study for the past 1 year. To determine allergic response to fragrances, 18 additional fragrances in addition to the Korean standard and a commercial fragrance series were patch-tested in patients with suspecting cosmetic contact dermatitis. Over 80% of the patients were women, and the most common site was the face. Cinnamic alcohol and sandalwood oil (Santalum album L.) showed high frequencies of positive responses. Of the specific fragrances, ebanol, alpha-isomethyl-ionone (methyl ionone-gamma) and Lyral (hydroxyisohexyl 3-cyclohexane carboxdaldehyde) showed high positive responses. We compared the results obtained during this study with those of other studies and concluded that including additional fragrance allergens may be useful for the detection of fragrance allergy.

Linear congenital Becker nevus.

Becker nevus is an acquired disorder that usually manifests in late childhood or adolescence as a hyperpigmented hypertrichotic patch usually located on the upper trunk or proximal upper extremities. Only a few cases of congenital and familial Becker nevus have been described. Although the lesions may have various shapes, they consistently have a geographic or blocklike configuration in an irregular fashion; a linear pattern has rarely been reported. We describe a case of linear congenial Becker nevus following Blaschko line that appeared at birth on the right shoulder, with hypertrichosis developing 4 years later.

Treatment of Vitiligo with 308-nm xenon-chloride excimer laser: therapeutic efficacy of different initial doses according to treatment areas.

Many preliminary data suggest that the 308-nm excimer laser can be a highly effective therapeutic alternative for treating vitiligo, inducing rapid repigmentation with minimal ultraviolet irradiation. We evaluated the clinical efficacy of the 308-nm excimer laser treatment for various body areas, using different initial UV doses. One hundred forty vitiligo patches from 69 patients were assigned to 4 groups; face and neck, trunk, extremities, and acral and joint areas. They were then treated twice a week, using different initial UV doses. The rate of repigmentation continued to increase with the number of treatments up to 20 sessions, and then showed plateaus between 20 to 30 sessions. On the other hand, the lesions in acral and joint areas showed the worst responses throughout the treatment sessions. Our findings extend previous observations that the 308-nm excimer laser is an effective treatment option for patients with vitiligo. However, further studies will be needed to determine the optimal dosing and administration method, especially for acral and joint areas.

Basaloid carcinoma of the lung presenting concurrently with cutaneous metastasis.

Basaloid carcinoma of the lung is a rarely occurring form of lung cancer morphologically resembling the basal cell carcinoma of the skin. Although various histologic types of lung cancers have metastasized to the skin, basaloid carcinoma of the lung that shows cutaneous metastasis has yet to be reported. A 48-year-old man was admitted to our pulmonology department with mild dyspnea and a solitary cutaneous mass on the left portion of his chin. Chest radiography and computed tomography of the thorax revealed an irregular infiltrative mass confined to the central portion of the left lower lobe bronchus, which is a compatible finding of primary lung cancer. Microscopically, both a cutaneous mass and fine-needle aspirate material in the lung revealed the identical findings of basaloid morphologic patterns.
