Undifferentiated embryonal sarcoma of the liver in a young female: treatment with portal vein embolization and liver trisectonectomy

Undifferentiated Embryonal Sarcoma of the Liver (UESL) is a tumor highly malignant, of mesenchymal origin. It is a rare finding in adults, though less rare in children. The strategy to be followed and the therapeutic targets to be reached for this tumor, in adult cases, remain ambiguous and controversial. Herein we report the case of a 29 year old female patient with a massive UESL and we describe our therapeutic approach. A 29 year-old female patient was referred to our center with severe intermittent epigastric pain and fever due to a voluminous liver tumor: Needle biopsy was of no specific findings and surgical excision was decided. Right portal vein embolization and selective embolization of the segment's IV branch was performed in order to achieve adequate future liver remnant (FLR). Right trisectonectomy was then performed, with uneventful post operative period and the patient was discharged at the 11th post operative day. UESL is a rare tumor that needs aggressive surgical approach and multidisciplinary team management is of paramount importance.
