상부 위장관 출혈로 발현된 십이지장 양성 기질 종양 1예 = A case of duodenal benign gastrointestinal stromal tumor(GIST) with upper gastrointestinal bleeding

다국어 초록 (Multilingual Abstract)

Small bowel tumors comprise less than 5% of gastrointestinal neoplasm. Because of their rarity, a correct diagnosis is very difficult and often delayed. Gastrointestinal stromal tumors(GIST) are spindle cell tumors occuring mainly in adults with 5-year survivals of 50-56% and 10-year survivals of 35-43%. It is difficult that we concluded clinical manifestation of GIST. At the time of diagnosis, we already consider metastatic lesions as malignancy, which is suggested poor prognosis. Patients frequently complain vague intermittent abdominal pain. Occasionally they experience severe colicky pain because of tumor-induced partial intestinal obstruction. Factors playing a prominent role in predicting their biological behavior are tumor site, size, and degree of mitotic activity. Recently, we experienced one case of duodenal benign GIST in a 23-year-old woman who had epigastric pain and intermittent melena, so we report it with a review of the literature.
