Acute cholangitis in a patient with multiple bile duct procedures. After the biopsy, removal of bile duct stones released pus. Rounded, clear (edematous) portal tracts (arrows) separated by hepatocytes with dilated sinusoids (Row 1 Left 40X). Neutrophils about hepatocytes (arrows) have spilled into the lobule from a portal tract (Row 1 Right 200X). Proliferated bile ductules (arrows) bearing neutrophils within epithelium and lumens are features of obstruction that should prompt a search for interlobular ducts with acute inflammation (Row 2 Left 400X). The epithelium of the ducts can be severely degenerated. Neutrophils (cyan arrows) invade epithelium of an interlobular duct that are recognizable mainly as a circle of rounded nuclei; the associated arteriole (red arrow) should be identified to ensure an interlobular duct is being evaluated. Note the proliferated bile ductules (blue arrows) (Row 2 Right 400X). A PAS without diastase stain colors the arteriole (blue arrow), as well as the rim of the interlobular duct within which lies a neutrophil (cyan arrow) (Row 2 Right 400X). A PAS with diastase stain colors the arteriole (red arrow), as well as the rim of the interlobular duct within which lies a neutrophil (cyan arrow) (Row 1 Right 400X). | |||
