<p>(a) Photograph of a gross specimen enucleated from the liver shows a yellow infiltrative hard mass with no clear limits with the adjacent liver parenchyma. The periphery of this huge lesion composed of fibro-inflammatory tissue and small parasitic vesicles. (b) Photomicrograph (H-E staining, × 100) shows Brood capsule (arrowhead), inflammatory cell infiltration combine with stripe fibrous tissue and fatty degeneration (long arrow). (c) Photomicrograph (Masson staining, × 200) shows hyperchromatic blue stripe collagen fiber structure in the margin zone of HAE lesion (arrowheads). (d) CD34 antibodies (original magnification, × 200) shows large banding distribution brown microvascular structure in the margin zone of lesion (arrowheads). MVD = 28/HPF (0.72 mm<sup>2</sup>).</p
