Histopathology of vascular anomalies

Abstract

Over the past decade, many changes and updates have occurred in the world of vascular anomalies, including their histopathology. An appreciation has developed that a combined team approach is optimal in arriving at a correct diagnosis. Technical advances such as immunohistochemical stains for GLUT1, an excellent marker for infantile hemangioma, and vascular immunostains such as D2-40, PROX1, and vascular endothelial growth factor receptor 3, which distinguish lymphatics from arteries and veins, have been of immense help in daily practice.
