Vascular leiomyosarcoma is rare disorder and its prognosis is considered to be poor. Particularly, only a few reports have been published regarding primary leiomyosarcoma of the femoral vein. In the current study, we reported a case of primary leiomyosarcoma of the femoral vein, accompanied with a literature review. A 74-year-old woman was referred to our department with suspected deep vein thrombosis due to the swelling of her right lower extremity. A Hen’s egg-sized and non-pulsatile mass was palsated in the right inguinal region. Vascular ultrasonography revealed a 35×31×51 mm-sized mass, and a femoral venous aneurysm with thrombosis in the lumen was suspected. Furthermore, a tumor of the right femoral vein was suspected based on CT and MRI findings, and primary neurogenic tumor was listed in the differential diagnosis. The operative finding revealed that the mass was connected to the femoral vein, and a primary neurogenic tumor was ruled out. The mass was diagnosed as a tumor of the femoral vein, and complete resection was performed. Moreover, pathological examination of the mass revealed a primary leiomyosarcoma of the femoral vein. After the patient was discharged, she was observed by our department along with the hematology-oncology department at our hospital. Multiple metastases of the lung and liver were confirmed 4 months after the operation, and chemotherapy was initiated. She remains alive 2 years after the operation.
