내경정맥 혈전증으로 발현된 위선암

The migratory thrombophlebitis and thromboembolic disorders of the venous and arterial systems in the setting of malignancy are termed Trousseau's syndrome. The overall incidence of clinical thromboembolic events in patients with cancer has been reported to vary between 1.11%. Pancreatic carcinoma has been associated with the greatest risk of thromboembolic events. Other tumor type also prone to an increased risk of thromboembolic events, including lung, prostate, stomach, acute leukemia and colon cancer. Hypercoagulability associated cancer may result from activation of coagulation, injury to the endothelium, or alteration of blood flow. Unlike other coagulopathies, Trousseau's syndrome may manifest with thromboses in unusal areas, including the upper extremities, face and visceral organs. Neck vein thrombosis associated with distant cancers have been rarely reported. Jugular vein thrombosis associated with gastrc cancer is very rare. We report one case of gastic adenocarcinoma presented as internal jugular vein thrombosis. (Korean J Med 63:552-556, 2005) Key Words : Stomach, Neoplasm, Thrombosis
