Leiomyosarcoma of femoral vein in an adult.

A middle aged female presented with a swelling in the groin on the left side. On examination, it was an oval mildly tender firm mass, adherent to underlying structures and extending into the pelvis with pulsatility and bruit. It was diagnosed as leiomyosarcoma of femoral vein on fine needle aspiration cytology and selective left common iliac and common femoral angiography of the lesion. En-bloc wide excision of the mass including the femoral vessels was carried out with saphenous vein graft interposition for restoration of vascular continuity for both vessels. Femoral nerve was sacrificed for tissue clearance. The defect was large and led to permanent limp and walk with a support. The lady was followed up for two years. She was found to have no local recurrence or detectable metastases.
