목적: 조기 위암 중 점막하층 침윤과 림프절 전이가 많은 표층 팽창형 조기위암(5cm 이상)은 다른 형태의 조기위암과 다른 임상병리학적 양상을 보인다. 이에 저자들은 조기 위암 중 표층 팽창형 조기위암에 대해 임상 병리학적 특성과 수술 방법 및 예후에 영향을 주는 요소들을 알아보고자 하였다. 대상 및 방법: 1995년부터 2002년까지 단국대학교 외과학교실과 울산대학교 서울 중앙병원 외과학교실에서 위암으로 수술을 시행한 환자들 중 조직 병리 검사상 조기 위암으로 보고된 환자를 대상으로 하였다. 1,875예의 조기위암 환자 중 표층 팽창형 조기위암 300예($16.0\%$), 소형 조기위암 739예($39.4\%$)를 대상으로 임상병리조직학적 소견, 수술방법, 생존율, 재발 양상 및 재발률 등을 후향적 방법으로 비교 분석하였다. 결과: 양 군에서 육안적 소견상 IIc형이 가장 많았으며, 융기형보다 침윤형이 더 많았다. 양 군에서 수술방법의 차이는 없었다. 점막하층 침윤정도는 표층팽창형군이 185예($61.7\%$)로 소형군 294예($39.8\%$)보다 많았으며 두 군간에 통계학적으로 유의한 차이를 보였다(P=0.005). 림프관 침범은 표층팽창형군에서 39예($13.0\%$). 소형군에서 34예($4.6\%$)에서 관찰되었고 통계학적으로 유의한 차이를 보였으며(P=0.009) 종양의 재발은 표층팽창형군 300예 중 11예($3.6\%$), 소형군 739예 중 10예($1.4\%$)로 두 군 간에 통계학 적으로 유의한 차이는 없었다(P=0.214). 전체 5년 생존율은 표층팽창형군 $84.8\%$, 소형군 $93.0\%$로 통계학적으로 유의한 차이는 없었고(P=0.052), 5년 무병 생존율은 표층팽창형군 $87.5\%$, 소형군은 $94.7\%$로 통계학적으로 유의한 차이는 없었다(P=0.053). 결론: 표층팽창형 조기위암은 점막하층 침범, 림프관 침범, 림프절 전이는 빈도가 유의하게 많았다. 따라서 축소 수술 등은 적응이 되지 않으며 충분한 절제연과 광범위의 림프절 곽청술을 시행하는 것이 적절하다고 생각한다.

Cervical necrotizing fasciitis is a rare but well known life-threatening soft tissue infection primarily affecting the superficial and deep cervial fascial planes. It may rapidly spread into the mediastinum along fascial planes. So, if proper diagnosis and prompt surgical debridement is delayed, the infection may cause descending necrotizing mediastinitis with extensive necrosis of overlying skin, destroying fascia and muscle. Therefore, the key to the successful outcome is early recognition and rapid initiation of definitive radical debridement. The authors report, along with a literature review, a case of cervical necrotizing fasciitis with atypical spreading into the lateral chest wall.

Russian rates for melanoma incidence and mortality are relatively low as compared to some other white populations but the tumor is of increasing importance. In this paper, data are based on a retrospective descriptive analysis of melanoma epidemiology and clinicopathological characteristics in Krasnoyarsk Territory belonging to the Siberian Federal District of the Russian Federation. The age-adjusted incidence and mortality rates for the period 1996-2009 were determined with subsequent retrospective analysis of clinicopathological data of 103 primary melanoma cases. Our results showed that incidence and mortality rates in the region under consideration match the Russian national trends and correspond to epidemiological data of the countries of Eastern Europe. Stratification of melanoma cases by age, sex, clinicopathological state and localization revealed a prevalence of lesions on the trunk and lower extremities. Most melanomas diagnosed were of superficial spreading type and the third Clark's level of tumor invasion and stage II according to AJCC. In spite of comparatively low rates of incidence and mortality the trend to increase of melanoma cases in the region under consideration obviously calls for more attention and further investigation.

Purpose: Malignant melanoma is a fatal tumor arising in the melanocytic systems of the skin. The incidence of malignant melanoma, formerly considered a rare tumor in Korea, is observed to increase. The aim of this study is to analyze the clinical and histopathological pattern of malignant melanoma in one institute. Methods: Thirty patients with ages ranging from 33 to 80 years, diagnosed as malignant melanoma at our skin tumor department, were enrolled in a retrospective study over a 6 year period(2000. 9-2006. 7). The analyzed data included age, sex, location, duration before diagnosis, clinical type, level of invasion, and stage. Results: The cases were identified and analyzed by clinical and histopathologic study. The male to female ratio was 1:1.7. Lower extremities(especially, feet) were favored sites. The majority of cases were acral lentiginous melanoma(40%), followed by nodular melanoma (36.7%), superficial spreading melanoma(20%) in this study. Clark level IV was predominant in histopathologic study. There was merely narrow gap among each stage by AJCC. Conclusion: The clinicopathological characteristic of melanoma in our patients is quite different with that in the West. In this retrospective study, primary lesions of the foot were predominant with melanoma, and a high percentage of these were classified pathologically as acral lentiginous melanomas. Patients had a more advanced stage of disease at first presentation and a more deeply invasive primary lesion than Western patients. These suggest that malignant melanoma has a worse prognosis in our patients than in the West. So, further organized prospective studies are needed to approach the prudent and accurate diagnosis and management of melanoma in Korea.
