Pale, enlarged hepatocytes may be mistaken for normal or interpreted as fixation artifact
• Fatty liver disease
Pale, enlarged hepatocytes may be misinterpreted as ballooning hepatocyte degeneration
• Glycogen storage disease
No history of diabetes mellitus
Pale Swollen Hepatocytes Without Inflammation Needle biopsy of the liver shows diffuse hepatocyte swelling, imparting an overall pale appearance. Steatotic vacuoles are absent or rare. There is no lobular inflammation.
Cytologic Features Liver biopsy from a patient with glycogenic hepatopathy shows diffuse enlargement of hepatocytes with pale, wispy cytoplasm and prominent cytoplasmic membranes . Glycogenated hepatocyte nuclei are common.
Sparing of Portal Tracts The portal tracts appear normal in glycogenic hepatopathy . They contain their normal structures, and there are no portal inflammatory cell infiltrates. The background hepatocytes are diffusely swollen and filled with glycogen.
Hepatocytes: PAS Stain PAS stain highlights the abundant glycogen in hepatocytes in a liver biopsy from a patient with glycogenic hepatopathy.
