Delayed diagnosis of leiomyosarcoma of the common femoral artery after endovascular repair.
OBJECTIVE
To describe a unique case of misdiagnosed leiomyosarcoma of the common femoral artery presenting with signs and symptoms of high-grade stenosis, which was treated with stent placement.


METHODS
A 31-year-old woman with a history of diabetes and hyperlipidemia had recurrent claudication and showed significant in-stent restenosis of the common femoral artery in a postoperative angiogram at 5 months. The patient's clinical stage remained unchanged after repeat percutaneous intervention, and leiomyosarcoma was diagnosed from surgical specimens. The patient underwent resection and repair of the involved artery. She has survived 30 months with no further evidence of local recurrence or systemic metastatic disease.


CONCLUSIONS
Endovascular repair may cause a long delay in the diagnosis of an arterial leiomyosarcoma mimicking peripheral occlusive disease.
