Hepatic Sclerosing Hemangioma with Predominance of the Sclerosed Area Mimicking a Biliary Cystadenocarcinoma

Figure 4

Histological appearances of sclerosing hemangioma. (a) Sclerotic area is manly present and cavernous hemangioma area (indicated by H) is partly observed. (Loupe image, HE stain). (b) Sclerotic area presents diffuse fibrosis. (HE stain, x40). (c) Histology of cavernous hemangioma. Note increase and dilation of medium sized veins with cavernous form in b (HE stain, x40). (d) The increased and dilated veins show positivity of CD31 immunostaining being a marker of endothelium in (c) (x40).
