Endoscopic Findings with GI Angiosarcoma Correspond with the Propensity of These Vascular Tumors to Cause GI Bleeding: Two Case Reports and Review of the Literature

Although the endoscopic appearance of gastrointestinal (GI) angiosarcoma has been described in seven individual cases, the characteristic endoscopic appearance of this GI lesion has not been reported. The published cases report involvement of stomach (2) [1, 2], duodenum (4) [2, 3, 4, 5], jejunoileum (2) [6, 7], and colon (1) . This report presents two GI angiosarcomas, comprising the first published endoscopic images of esophageal angiosarcoma and the second endoscopic images of gastric and colonic angiosarcomas; in addition, this report proposes the novel finding, based on literature review of all nine published cases, of a characteristic endoscopic appearance of this GI tumor that corresponds with its highly vascular nature and its tendency to cause GI bleeding.
GI angiosarcomas with endoscopic characterization, including endoscopic photographs, were identified by computerized analysis of pathology reports from 2000 to 2012 at William Beaumont Hospital, Royal...
