Abstract

Ground-glass (GG) hepatocytes are classically associated with chronic hepatitis B (HBV) infection, storage disorders, or cyanamide therapy. In a subset of cases, an exact etiology cannot be identified. In this study, we sought to characterize the clinical, histological, and ultrastructural findings associated with HBV-negative GG hepatocytes. Our institutional laboratory information system was searched from 2000 to 2019 for all cases of ground-glass hepatocytes. Ten liver biopsies with GG hepatocellular inclusions and negative HBV serology, no known history of storage disorders, or cyanamide therapy were reviewed. Half of the patients had history of organ transplantation and/or malignancy. These patients took on average 8.1 medications (range: 3–14) with the most common medications being immunosuppressive and health supplements. Histologically, GG hepatocytes show either peri-portal or centrizonal distribution. The inclusions are PAS-positive and diastase sensitive. Electron microscopy showed intracytoplasmic granular inclusions with low electron density, consistent with unstructured glycogen. In summary, GG hepatocytes are a rare finding in liver biopsies, but are more common in patients with hepatitis B. They can also be seen in HBV-negative patients who have polypharmacy. In these cases, they are the result of unstructured glycogen accumulation putatively due to altered cell metabolism.
