Autoimmune hepatitis (AIH) was considered based on the immunohistochemistry results showing HBsAg (–), CD138 (plasma cell+), CMV (-), D-PAS staining (no alpha-1-antitrypsin granules), iron staining (slight hemosiderin deposition in liver cells), and in situ hybridization staining for EBER (-). The gene discussed is SDC1; the disease is autoimmune hepatitis.
