title: [Undifferentiated (embryonal) sarcoma of the liver. Report of a case].
abstract: A 15-year-old woman who was studied because an abdominal mass at the Instituto Nacional de la Nutricion Salvador Zubiran (INNSZ) is reported. The history revealed only malaise and mild abdominal pain. At physical exploration, an abdominal mass in the upper right quadrant was found. Liver function tests were normal. Abdominal ultrasound and computerized tomography revealed a large cystic mass of the right hepatic lobe. She underwent exploratory laparotomy. Intraoperative frozen sections of the biopsies demonstrated undifferentiated sarcoma of the liver, and an extended right trisegmentectomy was performed. Postoperative outcome was uneventful. Adjuvant treatment with doxorubicin and dacarbazine was given, and at six months of follow-up, the patient is alive without any evidence of recurrence. Clinical and histopathologic features of this rare malignant tumor are discussed, as well as the therapeutic choices.
