Intravascular Fibrolipoma of the Femoral Vein

Lipoma of the lower leg vein is rare, and the histopathological variant, fibrolipoma, is even rarer. Here, we report an intravascular fibrolipoma located at the junction of the deep femoral vein and the femoral vein in a 50-year-old male patient. Tumor resection and venous reconstruction with a prosthetic graft were performed. Eight months later, the patient was asymptomatic and did not exhibit swelling. To our knowledge, this is the first case report of an intravascular fibrolipoma in the literature. Lower vein venography, computed tomography venography, ultrasonography, and histologic images are presented, along with a description of the procedures employed for tumor resection and venous reconstruction.
