[Recurrent lower gastrointestinal bleeding due to a gastrointestinal stromal tumor (GIST) of the small intestine].

Gastrointestinal bleeding is a common cause of hospitalisation. In most patients, the origin and location of bleeding can be established in routine endoscopic and radiological examinations. The undiagnosed cases of so-called gastrointestinal bleeding of unknown origin require more sophisticated diagnostic methods. We present a case of 35-year old man with recurrent gastrointestinal bleeding due to a gastrointestinal stromal tumor of the jejunum that was revealed in the visceral angiography.
