[Aortic sarcomas with peripheral emboli: apropos of 2 cases]. / Sarcomes aortiques avec embolies périphériques: à propos de deux cas.

ABSTRACT

The authors report two cases of aortic angiosarcomas. These cases were similar and characterized by a typical pejorative clinical course, with peripheric emboli and many osteolytic metastasis. Immunohistochemical study was in favour of an endothelial origin, electronic microscopy indicated a mixed tumor with myofibroblasts and poorly differentiated endothelial cells. Differential diagnosis between angiosarcoma, leiomyosarcoma and intimal sarcoma are reviewed.
