The concept of perivascular myomas was recently proposed to designate perivascular myoid tumors arising from pleuripotent perivascular cells like smooth muscle cell cells, pericytes and glomus cell. They represent a histological continuum between three categories; myofibromatosis, glomangiopericytoma and myopericytoma. Myopericytoma is a rare, soft tissue tumor that primarily occurs in the skin and the subcutaneous and soft tissues of the extremities, but very few cases have been reported in other locations, which occurred in our present case. We herein report on a rare case of myopericytoma that developed on an unusual location, that is, the ear. The patient was a 35-year-old man who had a painless, slowly-growing red nodule on the upper auricle of the right ear for 5 years. The nodule was revealed to be a well-circumscribed mass composed of round to oval cells that strongly expressed smooth muscle actin. These cells were arranged in the concentrically multilayered pattern and they were surrounded by small to medium-sized vessels. (Korean J Dermatol 2009;47(11):1304~1308)

Background: Despite the physical disfigurement, bothersome symptoms and psychological problemsfrom the proliferative scarring process of keloids and hypertrophic scars, there is currently no consensus regarding the best management of these lesions. Objective: The purpose of this study was to determine the therapeutic efficacy and safety of intralesional corticosteroid injection combined with 5-fluorouracil (5-FU) and/or pulsed dye laser (PDL) in Koreans with keloids or hypertrophic scars. Methods: Twenty-five patients with keloids and/or hypertrophic scars over 2 cm in size or who had more than 3 separated lesions were included in this study. Each scar was divided equally into 2 or more segments and these were treated with 1 of the following 3 different modalities: (1) intralesional injection of triamcinolone acetonide (TCA: 20 mg/ml weekly), (2) intralesional injection of TCA 0.1 ml (40 mg/ml) mixed with 5-FU 0.9 ml (50 mg/ml) weekly and (3) treatment #2 combined with PDL (585 nm, 5∼7.5 J/cm2) at baseline and at the 3rd and 7th weeks. We estimated the change of the height, the erythema, the pliability, the pruritus, the pain/tenderness scores, the patient-self assessment and the complications. This study was an 8-week prospective study and the assessment of relapse was done at 4 and 12 weeks after the last treatment. Results: There was a statistically significant improvement of the clinical signs and symptoms in all the treated groups. However, the 5-FU-treated groups had more sustained effects compared to the group that underwent TCA monotherapy with respect to flattening and pliability. Complications such as ulcerations, crusts and hyperpigmentation were more frequent in the 5-FU-treated groups. Conclusion: Although 5-FU may be preferable to TCA for improving the symptoms of keloids and hypertrophic scars, we believe it is prone to induce more complications in Koreans.

현대직조에 미친 바우하우스의 영향 : 직조공방을 중심으로

In modern times, art, design and craft actively interact with one another; in particular, woven fabric is an item that has many benefits to flexibly respond to change of time and periodic characteristics of each time. Textile, which has under gone constant transformation and evolution along the human history, has colorful and multi-faceted properties whether for artistic or for practical purposes, for its variety of materials, weaving methods, forms and colors. In particular, woven fabric of the 20th century has shown dramatic changes and growth as it was used as ornamental wall tapestry, three-dimensional work of art, and for industrial needs. Such transformation has been profoundly affected by emergence of new materials due to scientific and industrial development as well as contemporary art styles. This research focuses on the Bauhaus weaving workshop that greatly contributed to setting a new direction for woven fabric, breaking a way from the traditional paths. The Bauhaus disapproved of ‘art for art’ and advocated integration of art and craft; it attempted to bring together all forms of art based on craft. Supporters of the Bauhaus felt a need to have close network with modern figurative concepts and production facilities to realize their educational ideology. Accordingly, they conducted education on forms taught by artists such as Johannaes Itten, Paul Klee and Wassily Kandinsky, as well as craft education by skillful craftsmen. Such curricula sometimes confused students, and yet it motivated them to create new kinds of fabric through innovative and creative process. Their influence permeated the United States and all through the Europe even after the Bauhaus closed down. This research focuses on teachers that had much influence on the Bauhaus and other fabric workshops and major fabric artists who worked as a bridge to connect Bauhaus advocates with the next generation. The Bauhaus’s direct and indirect influence on fabric artists who were active in the 20th century is also examined. By rediscovering long-lasting impact of the short-lived Bauhaus on art, design and craft fields, there search is expected to contribute to setting a future direction for fiber art.
