    Papillae vs pseudopapillae: True papillae are outgrowths of epithelium, surrounding fibrovascular cores of stroma and at least one blood vessel. In contrast, pseudopapillae (such as in solid pseudopapillary tumours) are nests of proliferating cells that eventually grow to become almost back-to-back, with cells in the centers of nests disintegrating, leaving rims of cells lining the periphery ...

    Focal nodular hyperplasia's most recognizable gross feature is a central stellate scar seen in 60–70% of cases. Microscopically, a lobular proliferation of bland-appearing hepatocytes with a bile ductular proliferation and malformed vessels within the fibrous scar is the most common pattern.
