Angiographic features of fibromas and fibrosarcomas

I Yaghmai

Angiography was done in 38 cases of pathologically-confirmed fibrous- tissue tumor. All benign fibromatous tumors and one case of desmoid fibroma were angiographically normal. A great spectrum of angioarchitecture exists in fibrosarcomas, whether they are of bone or soft-tissue origin. Heterogeneous vascularity was seen in 55% of these cases, and was related to the cell composition of the tumor. There exists a close relationship between the number of vessels in a tumor and its degree of clinical and histopathological malignancy. The most vascular part of a tumor is the least differentiated and should be used for biopsies. Angiography can be used for the grading of fibrosarcomas, and probably for assessing clinical prognosis.
