Trousseau sign of malignancy
The Trousseau sign of malignancy or Trousseau's Syndrome is a medical sign involving episodes of vessel inflammation due to blood clot (thrombophlebitis) which are recurrent or appearing in different locations over time (thrombophlebitis migrans or migratory thrombophlebitis). The location of the clot is tender and the clot can be felt as a nodule under the skin.〔(Trousseau's sign of visceral malignancy ) in GPnotebook, retrieved November 2012〕 Trousseau's syndrome is a rare variant of venous thromboembolism (VTE) that is characterized by recurrent, migratory thrombosis in superficial veins and in uncommon sites, such as the chest wall and arms. This syndrome is particularly associated with pancreatic and lung cancer
Trousseau's sign can be an early sign of gastric or pancreatic cancer, typically appearing months to years before the tumor would be otherwise detected. Heparin therapy is recommended to prevent future clots. The Trousseau sign of malignancy should not be confused with the Trousseau sign of latent tetany caused by hypocalcemia.
==History==
Armand Trousseau first described this finding in the 1860s; he later found the same sign in himself, was subsequently diagnosed with pancreatic cancer and died soon thereafter.
Dr. Trousseau presciently attributed thromboembolism in malignancy to changes in blood composition rather than local inflammatory or mechanical forces. By correlating clinical observation with surgical and autopsy findings, Dr. Trousseau recognized that a localized cancer could induce a generalized hypercoagulable state in which thrombosis could occur elsewhere in the body, such as in extremities with visceral malignancy. Dr. Trousseau described several cases in which recurrent thrombosis was the presenting feature of visceral cancer, and his confidence in the utility of this connection led him to say, "So great, in my opinion, is the semiotic value of phlegmasia in the cancerous cachexia, that I regard this phlegmasia as a sign of the cancerous diathesis as certain as sanguinolent effusion into the serous cavities."
