Hepatic hemangioma, a common benign tumor of the liver, has caused great threats to the public health. Most patients have an excellent prognosis because of the benign nature of hemangioma. On some occasions, spontaneous rupture of hepatic hemangioma is rarely observed in patients. Therefore, a majority of scholars propose that surgery should be restricted to specific situations. In this case, w...

Hemangioma, the most common tumor of infancy, is a benign vascular neoplasm of unknown etiology. We show, for the first time to our knowledge, that endothelial cells from proliferating hemangioma are clonal, and we demonstrate that these hemangioma-derived cells differ from normal endothelial cells in their rates of proliferation and migration in vitro. Furthermore, migration of hemangioma endo...
