We report a case of a 57-year-old woman with an obscure gastrointestinal bleed who was found to have an extramural gastrointestinal stromal tumour (GIST), detected by capsule endoscopy, and confirmed by laparoscopically-assisted enteroscopy and resection. Currently, major modalities used for detection of GISTs include double-balloon enteroscopy, capsule endoscopy and CT. Endoscopic measures, including capsule endoscopy, are limited in their ability to detect GISTs with extramural growth, as these typically do not demonstrate obvious luminal abnormalities. This case report illustrates a case in which an extraluminal GIST causing recurrent gastrointestinal bleeding presented as an ulcer, as seen on capsule endoscopy.
