title: [Critical assessment of angiographic findings in malignant tumors of the extremities (author's transl)].
abstract: Five selected cases out of a total of 36 patients who had been investigated by angiography for tumors of the extremities are demonstrated in order to show the difficulties which can arise in the interpretation of their angiograms. In the subsequent discussion, the classical criteria of Dos Santos for malignant tumors are analyzed; in agreement with other authors, we state, that only unequivocal tumor vessels are characteristic of malignant processes. With certain reservations - especially in the differentiation of malignant and inflammatory processes - the parenchymal phase and the functional behaviour of the circulation permits conclusions to be drawn on the nature of the morbid changes.
