title: [A rare cause of severe gastrointestinal bleeding].
abstract: Upper gastrointestinal hemorrhage represents a common symptom in the internal medical practice. This Case Report depicts a severe gastrointestinal bleeding from an angiosarcoma that required multiple blood transfusion. As shown in this case, the actual cause may initially remain unclear. Repeated tissue sampling is mandatory to confirm a diagnosis and provide adequate treatment. Primary gastrointestinal angiosarcomas are extremely rare and highly aggressive malignant tumors that tend to grow multifocally and metastasise early. The only curative treatment option is radical surgery, thus an early stage diagnosis is crucial. Palliative care for metastatic angiosarkoma is currently a topic for clinical studies.
