Liver biopsy—Patient 3.
The liver parenchyma shows steatosis together with granular red, oncocytic hepatocytes in periportal areas, suggestive of mitochondriopathy. Small aggregates of macrophages characteristic of Gaucher disease (arrows) are also recognizable within the sinusoids (A, hematoxylin–eosin, original magnification × 10), better underlined after PAS staining (B, PAS staining, original magnification × 26).
