Abstract
Inferior vena cava (IVC) leiomyosarcoma is a rare malignant neoplasm more commonly seen in women in the fifth to sixth decade of life. Complete resection of the tumor with negative margins is the only therapeutical option that has demonstrated a survival benefit. This report presents a case of a 67-year-old woman affected by a lower segment IVC leiomyosarcoma incidentally detected during a chronic abdominal pain study. The patient was treated with tumorectomy, resection and ligation of the infrarenal IVC without signs or recurrence on a 12-month follow-up.

Soft tissue retroperitoneal leiomyosarcomas are rare malignant tumors that account for 0.5% of all sarcomas in adults and carry a poor outcome [1-3]
Most information about treatment comes from case reports or small series, and complete resection of the tumor with negative margins is the only therapeutical option that has demonstrated a survival benefit [3,7-9]
We present a case of a lower segment inferior vena cava (IVC) leiomyosarcoma incidentally detected during a chronic abdominal pain study
Summary
Soft tissue retroperitoneal leiomyosarcomas are rare malignant tumors that account for 0.5% of all sarcomas in adults and carry a poor outcome [1-3]. The vascular system is the most commonly affected arising from the smooth muscle cells of the inferior vena cava (IVC) in half of the cases [1,4,5]. It is more common in women in the fifth to sixth decade of life [1]. Surgical approach by transverse abdominal incision is done, and the retroperitoneal mass arising from segment I IVC was exposed through a Kocher maneuver and right colon mobilization from the renal to the iliac veins. At 12-month follow-up, the patient has no abdominal pain, and the CT shows that there are no radiologic signs of recurrence She is on a careful follow-up program by the oncology department, and no adjuvant therapy has been performed
