Figure 1: Intravascular papillary endothelial hyperplasia (IPEH). (a) Papillary structures within a vascular space, lined by monolayer and nonatypical endothelial cells, characterized this lesion (H&E, objective 20x). (b) Several intravascular fibrin deposits are seen (arrows) (H&E, objective 40x). (c) An exuberant, partly organized, and recanalyzed thrombus is shown (H&E, objective 10x). (d) As in (c) at higher magnification (H&E, objective 20x).
