A, Photomicrograph of hematoxylin-eosin–stained sections showing a nodular vascular lesion composed of small capillaries arranged in a lobular fashion. The lesion in some parts appeared to be bordered by a vessel wall (black arrow). Fragments of unremarkable vessel walls were also present (original magnification ×40). B, Photomicrograph of vascular channels lined with endothelial cells devoid of atypia and containing occasional erythrocytes (hematoxylin-eosin stain, original magnification ×400).
