Postinfantile Giant Cell Hepatitis Secondary to Rheumatoid Arthritis.

Postinfantile giant cell hepatitis (PIGCH), also known as syncytial giant cell hepatitis, continues to be a poorly defined and rare disease presentation in the adult population. Although a common finding in neonates, there is limited literature on the disease process, causes, and treatment success of PIGCH in adults. A strong association between autoimmune disorders and PIGCH, considerably so in the case of autoimmune hepatitis, has been established.
