Abstract: This is a case report of a 40-year-old man with leiomyosarcoma of the inferior vena cava. He had suffered from shortness of breath and edema on lower limbs over several months. Clinical examinations including UCG, CT and MRI revealed the mass in the right atrium. The stalk of mass was located near junction of the right atrium and inferior vena cava by cavography. He was operated upon using extracorporeal circulation. The tumor originated from inferior vena cava, measuring 8.5×5.5×4.8cm in size, 130g in weight, was successfully removed. Partial defect of anterior wall on the inferior vena cava was reconstructed using Gore-Tex patch. Histologically, the tumor was composed of the spindled cells with arranged bundles. Immunohistochemically, they were positive for Dessmin and Vimentin. Seven months after the surgery, he has been followed at OPD. In review of the Japanese literature to our knowledge, only 14 cases were reported including this case.
