Leiomyosarcoma of Inferior Vena Cava and Right Atrium with Ascites and Jaundice: A Case Report.

Leiomyosarcoma is one of the soft tissue sarcomas that could originate from different parts of body and are mostly presented as retropritoneal mass. Leiomyosarcomas of vascular origin are particularly rare tumors occurring mainly in inferior vena cava (IVC). Here, we report the case of a 35-year-old male patient who presented with ascites and jaundice. Further evaluation revealed large hepatic and cardiac masses with extension to IVC. Since it was not possible to determine the point of origin of leiomyosarcoma, the patient received chemotherapy under diagnosis of metastatic leiomyosarcoma but unfortunately passed away.
