Abstract
Persistent sciatic artery (PSA) is a very rare, but clinically significant, congenital anomaly. PSA is known to undergo aneurysmal formation; however, there have been no previous reports of a soft-tissue sarcoma arising from a PSA. We describe a 79-year-old woman with a 10 year history of a slowly growing mass on her right buttock. Physical examination revealed a painful, firm, pulsatile mass with a maximum diameter of 13 cm. Computed tomography angiography revealed that the mass arose from the PSA. We successfully excised the mass lesion with no postoperative circulatory disturbances. The final pathological diagnosis was aneurysmal PSA that focally developed secondary angiosarcoma.
