AIM: 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. CONCLUSION: Albeit not being common, gastrointestinal stromal tumors can represent a source of substantial gastrointestinal hemorrhage.<\/jats:p>","DOI":"10.1590\/s0004-28032003000300010","type":"journal-article","created":{"date-parts":[[2005,4,15]],"date-time":"2005-04-15T14:20:55Z","timestamp":1113574855000},"page":"188-191","source":"Crossref","is-referenced-by-count":1,"title":["Upper gastrointestinal hemorrhage due to duodenal stromal tumor"],"prefix":"10.1590","volume":"40","author":[{"given":"Jos\u00e9 Gustavo","family":"Parreira","sequence":"first","affiliation":[{"name":"'Santa Casa' School of Medicine,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wilson de","family":"Freitas","sequence":"additional","affiliation":[{"name":"'Santa Casa' School of Medicine,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Samir","family":"Rasslan","sequence":"additional","affiliation":[{"name":"'Santa Casa' School of Medicine,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"712","DOI":"10.1001\/archsurg.1968.01330230020004","article-title":"Combined duodenal pancreatic trauma: The role of end-to-end gastrojejunostomy","volume":"96","author":"Berne CJ","year":"1968","journal-title":"Arch Surg","ISSN":"http:\/\/id.crossref.org\/issn\/0004-0010","issn-type":"print"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"421","DOI":"10.1007\/s002689910067","article-title":"Tumors of small intestine","volume":"24","author":"Blanchard DK","year":"2000","journal-title":"World J Surg","ISSN":"http:\/\/id.crossref.org\/issn\/0364-2313","issn-type":"print"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"1037","DOI":"10.1097\/00005373-199606000-00035","article-title":"Evolution in the management of duodenal injuries","volume":"40","author":"Carrillo EH","year":"1996","journal-title":"J Trauma","ISSN":"http:\/\/id.crossref.org\/issn\/0022-5282","issn-type":"print"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"341","DOI":"10.1016\/S0002-9610(66)80009-0","article-title":"Traumatic perforation of duodenum","volume":"111","author":"Donovan AJ","year":"1966","journal-title":"Am J.
