We report a case of synovial sarcoma of liver in a 44 year old man, presented as a tumor mass in left hepatic lobe. The patient was admitted at the hospital with clinical symptoms of acute abdomen and severe pain in the right upper quadrant.
Imaging examinations showed a tumor mass in the left hepatic lobe and free liquid in the abdominal cavity, due to the rupture of the tumor. A resection of 2 segments of the left hepatic lobe, where the tumor was located, was performed. Morphological, immunohistochemical and FISH studies confirmed the diagnosis of monophasic synovial sarcoma. Additional clinical and imaging examinations, made after the surgery, did not confirm tumor mass in any other localization. The patient refused any therapy other than surgery, at that time.
A relapsing tumor mass was found 6 months later and another surgical intervention was done. The patient received five monotherapy cycles of Doxorubicin, 75 mg/m2, after the second surgical intervention. He is still alive 11 months after the first operation receiving the same therapy and having second relapsing inoperable tumor mass filling the retroperitoneal space and a great fraction of the abdominal cavity.
