유건종은 근초나 근건막 연조직에서 유래하는 양성 섬유종증으로 매우 드물다. 원인은 밝혀지지 않았으나 수술을 포함한 외상, 에스트로겐, 유전적 결함 등이 관여한다고 알려져 있다. 저자들은 진행성 위암으로 인한 전위절제술 이후 복강 내 종괴가 발생하여 시행한 수술에서 유건종으로 진단되었으나 제거치 못하고 경과관찰 중 자연소실을 경험하였기에 문헌고찰과 함께 보고한다. Desmoid tumor is rare neoplasm characterized by clonal proliferation of myofibroblasts that do not metastasise, but often exhibit an infiltrative pattern and functional impairment. The etiology of this tumor is unknown, but hormonal, genetic, and physical factors play a role in its development and growth. The clinical behavior and natural history of desmoid tumors remains unpredictable and enigmatic. However, spontaneous regression of desmoid tumors is rare. Here we report spontaneous regression of an intraabdominal desmoid tumor in a patient who underwent total gastrectomy. (Korean J Med 2011;81:487-491)

Antiphospholipid syndrome (APS) is characterized by a combination of arterial/venous thrombosis or obstetric morbidity and antiphospholipid antibodies such as anticardiolipin antibody or lupus anticoagulant. Digital gangrene is an uncommon manifestation of primary APS. A 61 year-old woman was admitted because of acrocyanosis and progressive digital gangrene in both hands for 1 month. Serologically, lupus anticoagulant was positive. Angiography showed obstruction of digital arteries with collaterals, but there was no evidence of atheromatous plaque or vasculitis. Cardiac echogram did not reveal intracardiac thrombosis or valvular vegetations. She had no evidence of other thrombotic disorders, connective tissue disease, infections or malignancy. Treatment of intravenous heparin and prostaglandin E1 led to stabilization of the symptom, and the necrotic digits were surgically removed. Pathological examination of the amputed digital stump showed arterial and arteriolar thrombotic occlusion, proliferation of capillaries, and ischemic necrosis. After oral anticoagulation therapy, she has been followed without recurrence. We describe the first case of primary APS presenting as digital gangrene in Korea and review the literatures.

정보 보안을 위해 사용되는 DES 암호화 알고리즘은 강력한 쇄도효과를 갖고 있으며, 그 처리 속도 또한 매우 빠른 알고리즘이다. 하지만 H/W의 발달로 인해 DES의 비밀키의 길이가 56bits로 너무 짧기 때문에 전수키 조사 공격에 쉽게 노출되어 있다. 본 논문에서는 전수키 조사 공격에 취약한 DES 알고리즘의 비밀키 길이 문제 해결을 위하여 디지털 홀로그래피와 DES 알고리즘을 결합하여 DES의 비밀키 길이를 크게 증가시키는 새로운 방법론을 제시한다. 또한 제안한 DES 알고리즘의 암호성능을 테스트하기 위하여 쇄도효과를 측정하여 가능성을 검증한다. The DES encryption algorithm employed in information security has a strong avalanche effect, and the processing speed to encrypt is also fast. However, due to the H/W advances, the secret key length of DES having 56bits is not enough so that it is easily exposed to brute force attack. In this paper, we present a new method to significantly increase the secret key length in the DES by integration of digital holography and DES algorithm. In addition, we evaluate the encryption performance of the proposed method by measuring the avalanche effect and verify the possibility of it.

True non-parasitic splenic cysts are rare. Series have reported over 30 cases of true splenic cysts producing elevated serum CA 19-9 levels. A 27-year-old woman presented with a painless mass in her left upper abdomen. Computed tomography (CT) of the abdomen showed a 16-cm cyst in the spleen. The serum CA 19-9 and CEA levels were 432 U/mL and 1.67 ng/mL, respectively. The cystic fluid CA 19-9 and CEA levels were markedly elevated. A splenectomy was performed. The pathology showed a benign true epidermoid cyst, which was negative for CEA. The serum CA 19-9 level returned to normal after removing the splenic cyst. This is the first reported case of a true benign splenic cyst producing high levels of CA 19-9 and CEA in Korea. (Korean J Med 76:348-351, 2009)

Wegener`s granulomatosis (WG) is a disease characterized by a granulomatous necrotizing vasculitis of small vessels. Although any organ systems can be involved, gastrointestinal involvement in WG is notably uncommon. We present a case of 67-year-old man who was admitted with abdominal pain and diarrhea lasting for 3 weeks. Colonoscopy and abdominal CT scan revealed vasculitis and multiple mesenteric lymphadenopathy. Jejunum and mesenteric lymph nodes biopsies confirmed limited form of WG. The present case indicates that WG might involve only gastrointestinal tract and the histological confirmation is important for diagnosis. (Korean J Gastroenterol 2010;55:331-335)
