Metastasizing sarcoma of the aorta. A case report.
Sarcomas of the great vessels are rats. We report a case of a metastasizing sarcoma of the aorta. The patient was an 82-year-old male who presented with a subcutaneous tumour, which was initially classified as a malignant fibrous histiocytoma. Autopsy revealed a polypoid sarcoma of the luminal aspect of the aortic arch with metastases to several organs. By means of immunohistochemical staining, the aortic neoplasm was classified as an undifferentiated intimal sarcoma. The morphology of intimal sarcomas is very heterogeneous, and, when metastatic deposits are present, there may be considerable problems in differential diagnosis.
