The goal of this chapter is to expand upon that chapter to include peripheral tumors of venous and lymphatic origin. It is well known that the classification of peripheral vascular tumors is very difficult and that the schemes have changed over time. These schemes have been based on a wide variety of characteristics, including morphologic criteria and clinical behavior. Classification challenges include both determining if a lesion is a tumor (hemangioma) or a vascular malformation (hamartoma) and further in determining if a tumor is benign or malignant. To further complicate the matter, many lesions contain both arterial and venous elements. We have attempted to include tumors with primarily venous components or those that arise in a vein. Because of this overlap, some of these lesions were already described in the arterial chapter 1 and are not discussed here. In this chapter, lesions are classified by the criteria of Calonje and Fletcher,1 which take into account both pathologic appearance and clinical behavior.
