Abstract
Undifferentiated embryonal sarcoma of the liver (UESL) in adults, especially over 30 years old, is quite rare. We report two adult UESL patients that one of them survived 62 months and one is now surviving more than 65 months treated with repeated hepatic resections and radio-frequency ablations. Although UESL is an entirely unusual and aggressive tumor, multidisciplinary treatments including repeated hepatic resections and radio-frequency ablations may provide a longer survival.
