A 63-year-old woman who had received hemodialysis therapy since she fell acute on chronic renal failure 4 years ago presented with multiple joint pain. Nephrocalcinosis was not detected by abdominal X-ray when hemodialysis therapy was initiated. Laboratory testing showed azotemia, anemia, hypoproteinemia and mild liver dysfunction but no liver cirrhosis. Biopsied bone tissue demonstrated numerous calcium oxalate crystal depositions. Laparoscopy revealed black liver in macroscopic view. Histological studies showed numerous lipofuscin-like dark brown granules were deposited in hepatocytes. The activity of alanine : glyoxylate aminotransferase (AGT) was less than 0.1 U/g in biopsied patient's liver tissue. Generally, clinical symptoms demonstrated by Japanese primary hyperoxaluria type I (PH-I) patients are milder than those of European patients. Some PH-I patients may successfully avoid urinary tract calcification unless they fall into oliguria by some other causes. The lipofuscin granules are most likely the source of the dark color. Massive deposition of the lipofuscin granules indicated that the duration of the liver metabolic abnormality had lasted for long time. Thus, black liver may be related to a mild form of PH-I.
