Dermatofibrosarcoma protuberans(DFSP) is an uncommon tumor that arises in the dermis. It is characterized by slow invasive growth, frequent local recurrence after excision and infrequent metastasis. We report a case of DFSP who presented with an erythematous, firm nodule with satellite lesion on the left quadrant of the abdomen in a 52-year-old female. Histopathologically, this tumor showed a uniform cellular proliferation of fibroblast in a storiform or cartwheel pattern in the dermis and subcutis. The peripheral portions of the tumor may have a deceptively bland appearance, approaching that of normal collagen.
부모 학대경험 수준에 따른 청소년의 휴대전화 의존도 관련 변인들 간의 구조적 관계: 또래애착, 자기조절학습능력, 내재화 및 외현화 문제행동을 중심으로

본 연구는 또래애착, 자기조절학습능력, 내재화 및 외현화 문제행동과 휴대전화 의존도 간의 관계를 살펴보고 학대경험 수준에 따라 어떤 차이를 보이는지 분석하는데 목적이 있다. 이를 위해 2015년 한국 청소년 정책연구원(KCYPS)의 6차년도 자료를 사용하였으며, 총 1,993명의 중학교 3학년 학생들이 응답한 자료가 본 연구에 활용되었다. 본 연구의 결과는 다음과 같다. 첫째, 중학생의 또래애착, 자기조절학습능력, 내재화 및 외현화 문제행동, 휴대전화 의존도는 학대경험 수준에 따라 차이가 존재하는 것으로 나타났다. 둘째, 두 집단 모두 또래애착이 자기조절학습능력을 향상시키고 내재화 문제행동을 감소시키는 것으로 나타났다. 또한 자기조절학습능력은 내재화 및 외현화 문제행동에 영향을 미치는 것으로 나타났다. 마지막으로 두 집단에서 유의미한 차이를 보이는 최종 경로는 또래애착에서 자기조절학습능력, 자기조절학습능력에서 외현화 문제행동, 외현화 문제행동에서 휴대전화에 이르는 경로로 나타났다. The purpose of this study is to investigate the structural relationships between peer attachment, self-regulated learning abilities, internalization and externalization of problem behaviors, that affect teenagers' mobile phone dependence. The study will then show an effective method to reduce mobile phone dependency by investigating the difference in each relationship according to level of abuse experience. This study used data from the 6th “Korea Child and Youth Panel Survey(KCYPS) 2015.” For this research, responses were collected from 1,996 middle school students(3rd grade). The results were as follows: First, peer attachment, self-regulated learning abilities, internalization and externalization of problem behaviors, and mobile phone dependency had differences according to level of abuse experience. Second, peer attachment affected self-regulated learning abilities and internalization of problem behaviors in both high and low levels in the abuse experience group. In addition, self-regulated learning abilities affected internalization and externalization of problem behaviors. Finally, there were statistically significant effects in both the groups: peer attachment affected self-regulated learning abilities, self-regulated learning abilities affected externalization of problem behaviors, and externalization of problem behaviors affected mobile phone dependency.

Background: Different distributions of cytokeratins (CKs) have been found in various layers of the epidermis and in the structure of cutaneous appendages. Benign tumors of the epidermis or cutaneous appendages usually retain the characteristic distribution of CKs of their origin. Objective and Method: To elucidate the nature and differentiation of various eccrine gland tumors, we performed immunohistochemical staining using a panel of monoclonal antibodies against CKs in a normal eccrire gland, syringoma, eccrine hidrocystoma, eccrine poroma and clear cell hidradenoma. The tissue distribution of various keratins in the normal eccrine gland was compared with that in varioas eccrine gland tumors. Results : With regard to CKs expression, the results indicated that syringoma represents a tumor differentiating toward both the uppermost part of the dermal duct and the lower intraepidermal duct, and eccrine hidrocystoma represents a tumor differentiating toward the luminal cell of the dermal duct of the eccrine gland. Eccrine poroma cells seemed to be most closed related to the uppermost dermal duct of eccrine gland. We also found that analyse distribution of CKs was insufficient to elucidate the histogenesis of clear cell hidradenoma. Conclusion : Analysing CKs is helpful in the analysis of epidermal neoplasms with differentiation toward the eccrine gland. (Kor J Dermatol 1996;34(1): 78-84)
