Figure 7a. (a) Low-power photomicrograph (original magnification, x10; hematoxylin-eosin stain) demonstrates vascular channels of varying size in the hemangioma. The vascular channels are lined with endothelium but contain no blood cells (B indicates one such channel). Note the surrounding fibroproliferative tissue with scarce liver parenchyma. (b) Low-power photomicrograph (original magnification, x40; hematoxylin-eosin stain) demonstrates a thrombosed vascular channel (B) within the hemangioma.
