Vasculitis constitutes a heterogeneous group of diseases that are defined by an inflammatory process of the vascular wall, with occlusion and distal necrosis. They are rare and may be primary or secondary infections, systemic disease or exceptionally to neoplasic disease. The association of vasculitis and neoplasia is uncommon; vasculitis occurs before, concomitantly or subsequently to the diagnosis of neoplasia. The most frequently associated are the hemato-oncology and then to a lesser extent the solid tumors. Cutaneous manifestations by affectation of “small vessel” are the most common. We present 2 exceptional clinical cases of vasculitis associated with cancer, the first case is about a 57 years old patient with lesions of small vessel associated with bronchopulmonary cancer and the second case is a 79 years old patient diagnosed with brain glioblastoma of high-grade and injuries in lower limbs with characteristics of small vessel vasculitis.
