Abstract
BACKGROUND AND METHODS: The differentiation between drug-induced autoimmune-like hepatitis (DI-ALH) and autoimmune hepatitis (AIH) can be confusing and challenging. We present a case of DI-ALH characterized by positive autoantibodies, elevated immunoglobulin G (IgG) levels and histology characteristics of giant cell hepatitis. RESULTS: A liver biopsy was performed for etiology clarification, DI-ALH was diagnosed. Following treatment with corticosteroids and azathioprine, the patient's liver function remained normal without recurrence. CONCLUSIONS: Distinguishing DI-ALH from AIH based on the possibility of discontinuing immunosuppression and the histological features. Clinicians need to investigate patient's medical history, serological tests, and pathological changes to establish a correct diagnosis.
