a) Photomicrograph of the histology slide (hematoxylin and eosin (H&E) staining) of the lesion. This shows the intravascular “tumor” with fibrin thrombus. The wall of the artery is seen to the right and the proliferation is to the left of the thrombus. b) Photomicrograph of the histology slide (H&E staining). Observation of the vascular mass shows proliferation of vascular channels within the lumen and the wall.
