title: Undifferentiated (embryonal) sarcoma of the liver.
abstract: A 10-year-old girl with undifferentiated (embryonal) sarcoma of the liver reported here had abdominal pain, nausea, vomiting and weakness when she was 8 years old. Chemical analyses of the blood and urine were normal. Serum alpha-fetoprotein was within normal limits. She died of cachexia 1 year and 8 months after the onset of symptoms. Autopsy showed a huge tumor mass in the liver and a few metastatic nodules in the lungs, which were consistent histologically with undifferenitated sarcoma of the liver. To our knowledge, this is the second case report of hepatic undifferentiated sarcoma of children in Japan, the feature being compatible with the description of Stocker and Ishaka.
