A 36-year-old woman with no relevant medical or surgical history was referred to our attention for abdominal diffuse pain and mild weight loss. No risk factors such as hepatitis, alcohol abuse, oral contraceptive use, or a family history of carcinoma were reported. Liver laboratory studies were unremarkable, except for elevated gamma-glutamyl transferase (138 U/L). Viral serology tests were negative, as were serum carcinoembryonic antigen, CA 19-9, and alpha-fetoprotein.
