Synovial sarcoma of the abdominal wall

Abstract

The survival rate for patients with SSAW is similar to that reported for synovial sarcoma in general. A high mitotic rate and the poorly differentiated subtype of synovial sarcoma both were associated with a poor prognosis and, to some extent, appear interrelated. Less favorable behavior also was noted when the tumors were large (> or = 5 cm). Pluripotential or arthrogenous mesenchyme may be implicated in the pathogenesis of these tumors.
