[Rare case of florid vascular proliferation of small intestine complicated with intussusception and bowel obstruction].
Vascular abnormalities of the intestines are unusual. We present a florid benign vascular proliferation of the jejunum in one adult patient, presented with intussusception. In this cases, the proliferation was sufficiently exuberant to raise the possibility of angiosarcoma as a diagnostic consideration. The patient was 81-years old female. The main clinical symptoms at presentation included abdominal pain and bowel obstruction. On exlorative laparotomy two jejunal masses were found. Histologically in these lesions a florid lobular proliferation of small vascular channels lined by plump endothelial cells extended from the submucosa through the entire thickness of the bowel wall. The endothelial cells showed minimal nuclear atypia, and mitotic figures were infrequent. The overlying mucosa showed ulceration with ischemic-type changes, and had features of mucosal prolapse. The presence of intussusception or mucosal prolapse in the case suggests repeated mechanical forces applied to the bowel wall as a possible etiologic factor.
