title: [Stewart-Treves syndrome. Immunohistochemical study apropos of 2 cases].
abstract: Two women (63 and 68 years) presented with primary angiosarcomas of the skin which had developed on an area of chronic lymphoedema after radiosurgical treatment for breast cancer 4 and 13 years earlier. Immunohistochemistry tests formally eliminated epithelial metastasis and produced evidence in favour of lymphatic or capillary vascular proliferation. Endothelial affinity for anti-factor VIII and positive tests for certain markers of intermediary filaments (actin, vimentin) confirmed the vascular and conjunctive tissue origin of the tumours.
