Leiomyosarcoma of the splenic vein.
Leiomyosarcomas are smooth muscle-derived tumors generally found intra-abdominally in the retoperitoneum, mesentery, or omentum. Only approximately 5% of these tumors originate from vessel wall smooth muscle. Those derived from the splenic vein are exceedingly rare, with only one previously published case in the literature. We present a second case of leiomyosarcoma of the splenic vein in a 58-year-old woman with 2 months of epigastric pain. A distal pancreatectomy was performed to include the tumor found centered in the splenic vein at the splenic and portal vein confluence and growing into the pancreas in the body on the posterior aspect. A saphenous vein patch was used for reconstruction.
