The fibrous band on right bears proliferating bile ductules; acinar arrangement on left shows holes much larger than canaliculi (Row 1 Right 100X).

Hepatocellular carcinoma, steatohepatitic variant. | |||
Fragments of tumor at low power mimic normal hepatocyte groups without portal triads (Row 1 Left 20X). Vacuoles, mostly small, occasionally become large enough to warrant the term “macrovesicular” [green arrows]. Note Mallory hyalin [red arrows] (Row 1 Right 400X). Chronic inflammatory cells bound some cancer cells (Row 2 Left 400X). Nuclear inclusions [arrows] are occasionally prominent [arrows] (Row 2 Right 400X). | |||
