Intraductal papillary neoplasm of common bile duct with associated invasive carcinoma. <br>The papillary tumor comprises mostly variably dilated acini (Row 1 Left 20X), but also shows areas of micropapillae (Row 1 Right 200X). Some areas within the non-invasive tumor showed necrosis, with the black pyknotic nuclei amid red debris (Row 2 Left 400X). Definite invasion was established low power by glands headed in perpendicular directions (Row 2 Right 40X). Embedded in fibroblastic response are non-acinar walls and isolated epithelial groups (Row 3 Left 400X). Also embedded in fibroblastic response are flat glands with nuclei showing loss of polarity (lack of respect for lateral intercellular borders shown by variable orientation to base of gland)  (Row 3 Right 400X).
