Figure 1
(a) and (b) tissue sections showing well-formed vascular channels embedded in a myxoid stroma. Note focal areas of abortive endothelial differentiation (hematoxylin and eosin stained sections, (a) magnification ×200 and (b) magnification ×400). Insert in (b) displays the presence of an intracytoplasmic vacuole containing a single erythrocyte (arrowhead) (magnification ×600). (c) and (d) neoplastic cells demonstrating strong diffuse immunoreactivity for the endothelial markers CD31 (c) and CD34 (d), magnification ×200.
