Figure 2

Histopathological findings of IPEH. (a) Photomicrograph showing thrombus in organization in the peripheral region (black stars) and intravascular papillary endothelial proliferation in the central region (red star) (H&E, ×4). (b) Close relationship between papillae structures in association with hemosiderin deposition (black star) and the thrombus (red star) (H&E, ×10). (c) Close-up of reactive papillary endothelial proliferation containing hemosiderin deposits (H&E, ×40).
