Keloids are benign fibrcus growths which extend beyond the original wound and rarely regress. Available methods of treatment include surgical excision, radiotherapy, intralesional steroid injection, cryotherapy, systemie. chemotherapy, zinc tape strapping, pressure, silicon gel and combined therapy. Postoperative irradiation is a useful and effective method of eradication or prevent.ion of keloid. We describe two cases of the prevention of keloids associated with post,operative irradiation.

In the real world, it is hardly expected that complete contract is made because of the existence of contract costs. Thus, corporate governance has been regarded as one of major control mechanisms to affect manager`s decision-making significantly. Several prior studies related to earnings management have indicated that the higher level of corporate governance is, the lower degree of earnings management is. Obviously, it somewhat looks like straightforward. However, earnings management literatures recently suggest that mangers are shifting earnings management strategy from accrual basis to real activity basis. After the accounting reforms, it is said that change in earnings management strategy tends to be fast. It may be attributable to the reinforcement of internal control over financial reporting because strengthened internal control system can easily detect accrual-type earnings management. In addition, real activity-based earnings management has far more important meanings than accrual-based earnings management because real activity-based earnings management can induce different sorts of consequences in contrast to accrual-based earnings management. For example, real activity-based earnings management significantly affects the future cash flows of the company. On the other hand, accrual-based earnings management does not affect cash flows themselves but adjust simply the timing of recognizing revenues or expenses. Therefore, it is important to focus on the strategic changes in earnings management in that real activity-based earnings management has great impacts on the long-term prospects of the company. If so, it indeed implies that we need additional evidences on the real activity-based earnings management in order to understand the earnings management practices. In this context, this study examined empirically that how much the level of corporate governance has an effect on the real activity-based earnings management by using the evaluation score from Korean Corporate Governance Services. As a result, we could find that the degree of earnings management through real activities(such as abnormal operating cash flows, abnormal production costs, and abnormal discretionary expenses) decreased as the level of corporate governance increased. It represents that corporate governance can play an important role in controlling managers` opportunistic behaviors on real manipulation. Additional test based on the scores of corporate governance subindices showed that they were negatively associated with real activity-based earnings management as a whole. In short, real activity-based earnings management is quite different from accrual-based earnings management in that it has direct cash flow consequences. That is, in a long-term perspective, real activity-based earnings management has unique characteristics compared to those of accrual-based manipulations. The empirical results of this paper that the level of soundness of corporate governance is strongly related to the degree of real activity-based earnings management can be an evidence to complement the existing literature on earnings management.

Background: Photodynamic therapy (PDT) is increasingly used for superficial skin cancers. However, there have only been a few reports on Bowen`s disease treated with PDT in the Korean literature. Objective: The purpose of this study was to evaluate the effectiveness and side effects of PDT in the treatment of Bowen`s disease. Methods: We treated 20 Bowen`s disease lesions in 15 patients using topical PDT containing 5-aminolaevulinic acid and a light-emitting diode device. The light intensity used was 100 mW/cm2 and the dosage was 140~220 J/cm2. Results: Complete clearance was achieved in 17 of 20 lesions (85%) after 2~4 treatment sessions. The only side effect was a stinging sensation, which occurred in 5 lesions (20%). Conclusion: PDT is a relatively effective and useful alternative therapy for treatment of Bowen`s disease.

Intramuscular lipoma is an unusual benign mesenchymal tumor, which infiltrates the skeletal muscle, and in exceedingly rare cases can occur on the head or neck. Intramuscular lipoma is composed of mature adipose tissue that infiltrates muscle in a diffuse manner, and the entrapped muscle fibers exhibit varying degrees of atrophic change. Because of infiltrating features of adipocyte, the recurrence rate after excision is very high. We herein report two cases of intramuscular lipoma of the chin. (Korean J Dermatol 2007;45(1):55~57)

Primary mucinous carcinoma is a rare malignant tumor that arises from the deepest portion of the eccrine duct. This tumor consists of large mucinous pool with fibrous septae and clusters of tumor cells. Immunohistochemical staining was studied for the differentiation, but has only limited value. We present a case of mucinous eccrine carcinoma in 56-year-old man and review the literature. (Korean J Dermatol 2006;44(9):1098~1101)

Objective : To evaluate the effects of isoflavone intake on estrogen deprivated symptoms in surgically menopaused women. Methods : Premenopausal women who took total hysterectomy with both adnexectomy were randomized into three groups. One group took conjugated equine estrogen 0.625 mg daily for 12 weeks after surgery, the second group took isoflavone 100 mg #3 daily for 12 weeks after surgery, and the third group took no medication for controlled group. Questionnaires about the acute menopausal symptoms, incontinence score, blood lipid profile, bone turnover marker were checked before and 12 weeks after surgery.

N/A Background : Frequent association of nevus sebaceus with other skin appendage tumors and with apocrine glands suggests that the nevus sebaceus may be derived from the primary epithelial germ. Syringocystadenoma papilliferum was found most frequently in the nevus sebaceus. A number of cases have been reported, but extensive studies on the secondary tumors of nevus sebaceus are rare in Korea. Objectives : The purpose of this study was to investigate characteristic clinical features in Korean patients with the secondary tumors of nevus sebaceus. Materials & Methods : Enrolled were total 136 patients confirmed as nevus sebceus at the Chungnam National University Hospital, the Dankook University Hospital, and the Chungbuk National University Hospital from March 1993 to February 2003 for this study. And we reviewed the Korean Journal of Dermatology and the Annals of Dermatology for nevus sebaceus with secondary tumors. Result : The results were as follows : 1. Total 45 cases were included from 23 males and 22 females. The male/female ratio was similar. Trichoblastoma(86% in female) and basal cell carcinoma(67% in female) were more frequent in female than in male. 2. Mean age was 38.7 years(range 1.5 years to 71 years). all malignant tumors except basal cell carcinoma developed beyond 40 years of age. 3. In the malignant tumors, 19(95%) or 20 cases developed in the scalp. However, in the benign tumors, 44(86.3%) of 51 cases developed in the scalp and 7(13.7%) of 51 cases in the face. 4. Tumors of one type developed in 29 cases and tumors of more than two types developed in 16 cases. 5. The total seventy eight tumors were composed of 23 malignant tumors and 55 benign tumors. Basal cell carcinoma and syringocystadenoma papilliferum were the most common tumor in each group respectively. Although trichoblastoma was not counted as the most common tumor, we suggest that it might be the most frequent tumor in secondary tumors associated with nevus sebaceus because differential diagnosis between trichoblastoma and basal cell carcinoma was so difficult that many cases of trichoblastoma were misdiagnosed as basal cell carcinoma.(Korean J Dermaton 2003;41(10) : 1338~1346)
