Abstract
Sarcomas are connective tissue tumors accounting for only 1% of all adult malignancies. Leiomyosarcoma (LMS) is a sarcoma arising from smooth muscle cells, and accounts for 10-20% of all sarcomas. A subtype of LMS are those originating from the smooth muscle of blood vessels. Leiomyosarcoma of the inferior vena cava is a sarcomatous tumor, with less than 350 cases described in the literature. It carries a poor prognosis, with 5- and 10-year survival rates of 31.4% and 7.4%, respectively. We present a case of a 46-year-old female with no significant past medical history presented to the emergency department with mild abdominal pain and distention, early satiety, and weight loss for three weeks, found to have unresectable metastatic leiomyosarcoma of the inferior vena cava.

Abstract
Benign smooth muscle tumors of the inferior vena cava (IVC) are unusual, but mostly consist of intravenous leiomyomatosis, which arises from the uterus. Primary leiomyoma of the IVC is extremely rare. Here, we report a primary leiomyoma of the IVC, misleadingly reported as a cystic neoplasm of the pancreas in images. Immunohistochemical analysis was positive for (estrogen receptor) ER and (progesterone receptor) PR, indicating gynecologic leiomyomas. The use of ER and PR immunostaining is recommended to help distinguish between somatic and gynecologic leiomyomas, whose criteria of malignancy differ.
