A A photograph of a freshly resected angiomatous ACP displaying a reddish, vascular surface in some parts (Vs) and a pale surface in others. B A photograph of a bisected angiomatous ACP to demonstrate a highly vascular cut surface (Vs). Note the well-defined, narrow pedicle (P) in both specimens. C Light microscopy of an angiomatous ACP shows the highly vascular stroma with multiple dilated vascular spaces of varying size (black arrows) (H&E; Â100). D Higher magnification shows that these vascular spaces are lined by a single layer of flat endothelial cells (black arrows) and separated by loose fibro-connective stroma that exhibited chronic inflammatory cellular infiltration and areas of interstitial hemorrhage (H&E; Â200)
