[Undifferentiated embryonal sarcoma in the liver of adults]
Background:
Embryonic sarcoma of the liver is uncommon in adults. We report an unusual case presenting as a cyst-like formation of the liver.
Case Report:
The pre-operative and also the peroperative histology diagnosis was remodelled biliary cyst. The patient was treated accordingly. The final diagnosis of embryonic sarcoma of the liver was made when a local recurrence developed. The patient underwent hepatic resection followed by a chemotherapy and radiotherapy protocol. Tumor markers were measured within the tumor and gave a positive result for CA-125.
Discussion:
Diagnosis of cystic forms of embryonic sarcoma can be a quite difficult task. Radiological and histological aspects can be helpful. This report is the first case in which tumor markers were measured within the tumor.
