There is no evidence which can demonstrate a better survival among trials and they are usually empiric due to the lack of experience. Patients usually die within 1 year from diagnosis or even on the late posoperatory period due to severe sepsis . Although some trials report certain association of the site of presentation with prognosis, other do not do it, specifically speaking of intestinal angiosarcomas; there are no guidelines referring to the follow up, which needs overall focused to detect metastasis and recurrence.
Main prognostic factors such as older age, status performance, high tumor grade and metastases are associated with a poorer prognosis, but it is unclear which is the main factor .

Recurrence cannot be discussed until metastases has been discarded and follow up in patients free of disease is documented. In Ni et al.
Our patient presented a very rare condition, that start with non specific symptoms, so we started the work-up finding an intestinal tumor and because the patient presented an hemodynamic deterioration, we decide to submit to surgery. Our patient had a history of unknown pelvic tumor and radiotherapy.
So, we suggest to consider the diagnosis of intestinal angiosarcoma in other patients with these features. After the pathology results, the patient was sent to oncologic management. Written informed consent was obtained from the patient for publication of this case. An Institutional Review Board approval was obtained before the publishing of this article.

Abstract Introduction Intestinal angiosarcomas are an extremely rare and aggressive vascular tumors, with a few cases reported in the literature.
Presentation of case A 45 years-old male arrived to our hospital with intermittent gastrointestinal bleeding presenting melena and weight loss, he has antecedent of pelvic radiotherapy ten years before admission for an unknown pelvic tumor. Discussion Angiosarcomas are aggressive tumors with a high rate of lymph node metastasis and peripheral organs. Conclusion We should keep in mind this tumors as a cause of obscure intestinal bleeding in patients with medical history of radiation therapy.
Keywords: Intestinal angiosarcoma, Obscure gastrointestinal bleeding, Radiotherapy. Open in a separate window. CT scan, coronal plane showing thickening of intestinal wall. Discussion Primary angiosarcoma of the small intestine is an extremely rare disease affecting mainly: liver, spleen, adrenals, ovaries, heart, lung, breast and, rarely, the middle gastrointestinal tract as in our case .
