[Leiomyosarcoma of the small intestine: a rare cause of gastrointestinal blood loss].

A 61-year old man is described with recurrent gastrointestinal bleeding, due to a metastatic jejunal leiomyosarcoma. Because of the low incidence and the aspecific symptoms, a long delay occurred until the bleeding tumour and its metastases were demonstrated at radionuclide scanning and mesenteric angiography. The tumour-bearing segment could be removed by simple surgical excision.
