Undifferentiated (embryonal) sarcoma of the liver (UESL) is a rare hepatic tumor and mainly occurs in children. It usually has cystic changes on computed tomography scan, which represents areas of necrosis and hemorrhages. UESL is a rapidly growing tumor and tumor rupture does occur. We reported a girl with a large multicystic hepatic tumor who died of tumor rupture shortly after the diagnosis of UESL. It is mandatory to be aware of this potentially fatal complication especially in patients with UESL of large tumor volume.

[Show abstract][Hide abstract] ABSTRACT: Undifferentiated embryonal sarcoma (UES) of the liver is a rare malignant neoplasm that mostly affects children younger than 15 years of age. We report a patient with UES in the right lobe that was complicated by haemorrhage after needle biopsy. The tumour was managed by embolization of the right hepatic artery and treated successfully with chemotherapy and surgical resection. Prophylactic embolization of the feeding artery should be undertaken before a biopsy procedure if there is the possibility of tumour rupture, in the presence of signs of intratumoral or peritumoral bleeding, or in the presence of a vascular liver mass.
