    Abstract:
    INTRODUCTION: Thromboangiitis obliterans is an inflammatory occlusive vascular disease of young smokers that commonly involves the small and medium sized arteries and veins of the extremities. An important differential diagnosis of thromboangiitis obliterans is atherosclerotic arterial disease. An atypical presentation of thromboangiitis obliterans by involvement of mesenteric arteries has been described sporadically. CASE PRESENTATION: We report the case of a patient presenting with Raynaud's phenomenon, ischemia of the upper and lower extremities, as well as mesenteric ischemia. The dramatic course of the disease advanced to gangrene of the calves and intestinal infarction. In this patient, angiographic and histologic features were consistent with thromboangiitis obliterans associated with atherosclerotic arteriopathy. DISCUSSION: A review of the literature revealed 31 reported cases of mesenteric artery involvement by thromboangiitis obliterans. The overlap between thromboangiitis obliterans and atherosclerotic arteriopathy is rare but has recently focused attention in the literature. CONCLUSION: In the differential diagnosis of mesenteric ischemia, thromboangiitis obliterans is a rare but important diagnosis that should be considered. In view of shared features of thromboangiitis obliterans and peripheral artery disease, awareness of their possible coexistence is needed in order to make the right diagnosis and offer proper treatment.
