RESUMO
Phototoxicity can be either harmful and induce adverse skin reactions or beneficial and be used therapeutically as in psoralen and UV-A or photodynamic therapy. Hundreds of medicinal plants are widely used in Asia and Western countries in oriental medicine, yet the phototoxicity of oriental medicinal plants is an understudied area. In this contribution, the authors discuss some methods used to measure the phototoxicity of plants and give an overview of the results of their previous and ongoing studies into the phototoxicity of medicinal plants. The authors argue that because they found that more than a quarter of oriental medicinal plants can be phototoxic, such research is helpful for dermatologists and that active phototoxic components extracted from oriental medicinal plants may be used therapeutically.

Lupus erythematosus profundus, a form of chronic cutaneous lupus erythematosus, is a rare inflammatory disease involving in the lower dermis and subcutaneous tissues. It primarily affects the head, proximal upper arms, trunk, thighs, and presents as firm nodules, 1 to 3 cm in diameter. The overlying skin often becomes attached to the subcutaneous nodules and is drawn inward to produce deep, saucerized depressions. We present a rare case of lupus erythematosus profundus treated with autologous fat transfer.

BACKGROUND: Acquired syndactyly is a rare disease that occurs mostly after disease, trauma, or other inflammatory conditions. It is usually treated by surgical incision with a flap or full-thickness skin graft, which is very invasive and requires hospitalization. OBJECTIVE: The objective was to treat acquired syndactyly with an epidermal graft by suction blister after radiosurgery, because this procedure is much less invasive and can be performed in an outpatient base. METHODS: A 65-year-old Korean woman had acquired syndactyly after various traditional treatments for tinea pedis. Five days after separation of syndactyly with radiosurgery, we prepared an epidermal sheet by suction blister, placed it on sterile meshed gauze, and applied it to the separated lesion. RESULTS: The patient's lesion was completely healed after 7 days. CONCLUSION: Gauze-fixed epidermal graft after radiosurgery is a very effective and simple treatment for shallow acquired syndactyly.
