trousseau´s syndrome mimicking severe bilateral peripheral arterial disease

We present the case of how a massive proximal deep vein thrombosis result of an unknown recurrence of a previously colonic malignancy treated, classically known trousseau´s syndrome, can mimic symptoms of severe peripheral arterial disease in a patient affected of peripheral chronic arterial disease surgically treated. trousseau´s syndrome is commonly associated with serious and chronic diseases and a variety of paraneoplastic thromboembolic disorders. thrombotic episodes may precede the diagnosis of cancer and be the potential marker for an unknown and occult malignancy. we highlight the key points of the trousseau´syndrome and those paraneoplastic vasculopathies related that can mimic a vascular disease or complication.
