Hypothesis-generating in one case; requires validation in larger cohorts before any prognostic use in cutaneous angiosarcoma.
The ultrastructural findings in four cases of angiosarcoma of the scalp are reported. There is some evidence that the presence of ultrastructural markers of normal endothelial cells, such as Weibel Palade bodies, within the tumour cells may be of prognostic value.
