Hepatic Angiosarcoma: An Unusual Case of Intractable Gastrointestinal Bleeding

Hepatic Angiosarcoma is an extremely rare malignant neoplasm of the vascular or lymphatic endothelium accounting for about 2% of all sarcomas. It is considered idiopathic in up to 70% of cases. We describe the case of a 32-year female transferred to our center for evaluation of intractable gastrointestinal bleeding. Definitive diagnosis remained elusive despite multiple endoscopic assessments with repeated cauterization of arteriovenous malformations (AVMs). Autopsy results confirmed metastatic hepatic Angiosarcoma.
