Two-stage combined treatment of leiomyosarcoma of iliac vein using robotic surgery

摘要

Vascular leiomyosarcoma is a rare tumor originating from the vascular smooth muscle cells. Leiomyosarcomas of the external iliac vein are extremely rare. Only single observations of this tumor are reported. We describe a 48-year-old woman who underwent a two-step combined treatment: robot-assisted removal of the extraperitoneal tumor and removal of the lower part of the tumor from the open femoral approach. There have been no signs of tumor recurrence during the 34-month follow-up period.
