Introduction:
Primary sarcomas of the great vessels, that is, the aorta, pulmonary artery, and inferior vena cava, are rare. They can be classified according to the location of the sarcoma in the vessel wall and by their gross appearance. Most often they are leiomyosarcomas or fibrosarcomas.
Case:
We report here a case of an intimal sarcoma of the inferior vena cava. Histological and immunohistochemical findings confirmed the diagnosis for this 17-year-old girl and distinguished it from leiomyosarcoma and angiosarcoma, both of which have better prognoses.
Discussion:
Intimal sarcoma of the inferior vena cava is rare and difficult to diagnose before surgery or biopsy. Histologically, it is a poorly differentiated tumor with the worst prognosis among the primary vascular sarcomas. Pathologic findings and immunohistochemical staining are useful for a positive diagnosis.

Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the middle...
Veins of the Abdomen and Pelvis
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...
