Gastrointestinal stromal tumor represents a rare neoplasm that originates in the muscular wall of the hollow viscera.
To report gastrointestinal stromal tumor as a source of upper gastrointestinal bleeding, which required urgent surgical control.
PATIENT/METHOD: A man with 61 years old was admitted to the emergency service sustaining hematemesis and melena. Endoscopy showed active bleeding from a tumor in the second portion of the duodenum, which was controlled by heater probe cauterization. Surgery was performed through a median laparotomy. A local resection of a 4 cm tumor in the second portion of the duodenum was carried out, together with a primary end-to-end anastomosis and a duodenal diverticulization. No complications happened during the post-operative period. Morphologic examination showed gastrointestinal stromal tumor with no atypical mitosis and a preserved capsule.
Albeit not being common, gastrointestinal stromal tumors can represent a source of substantial gastrointestinal hemorrhage.

报告以胃肠道间质瘤作为上消化道出血的病因，需紧急手术控制出血。
患者/方法：一名61岁男性因呕血和黑便入住急诊。内镜检查显示十二指肠第二部的肿瘤有活动性出血，通过热探头烧灼止血。经正中剖腹术进行手术。对十二指肠第二部一个4厘米的肿瘤进行局部切除，并进行一期端端吻合和十二指肠憩室化。术后无并发症发生。形态学检查显示为胃肠道间质瘤，无非典型核分裂且包膜完整。
尽管不常见，但胃肠道间质瘤可成为严重胃肠道出血的病因。
