Key result
Intravascular synovial sarcoma characteristically arises in large lower extremity and trunk veins of young females.
Why the study?
Intravascular synovial sarcoma is extremely rare, with only two prior cases reported, and its clinical pattern remains unclear.
Case Report (n=1)
Synovial sarcoma should be considered in the differential diagnosis of intravascular tumors, particularly in large veins of the lower extremity and trunk in young adult females.

May support considering synovial sarcoma in the differential for lower-extremity intravascular tumors in young women; leaves open validation in larger series.
A case of intravascular biphasic synovial sarcoma arising from the wall of the left femoral vein in a 34 year old woman is described. This is the third case of an intravascular synovial sarcoma known to be reported in the medical literature. The two previous cases arose from the left femoral vein and inferior vena cava in women of 34 and 31 years old, respectively. A characteristic clinical pattern appears to be emerging--that is, location in large veins of the lower extremity and trunk in young adult females. Synovial sarcoma must be considered in the differential diagnosis of intravascular "tumours".

Robertson et al. (1998) conducted a case report in Intravascular synovial sarcoma (n=1). Intravascular synovial sarcoma was evaluated. Intravascular synovial sarcoma is a rare tumor that appears to characteristically arise in large veins of the lower extremity and trunk in young adult females.
