In grade-2 lesions, the tumour is still easily recognizable as vasoformative and the endothelial cells have moderate atypia.
Atypical vascular proliferations, which have been described under various nomenclature designations, occur in areas of prior radiation, are often seen in association with angiosarcoma, and in some cases may be difficult to distinguish from vasoformative angiosarcoma.
Malignant vasoformative (angiogenic) tumors of the soft tissues of the head and neck account for fewer than 0.
Splenic hamartoma, otherwise known as splenoma or splenadenoma, is another rare vasoformative lesion of the spleen.
They are benign vascular malformations that originate in mesodermal nests of vasoformative tissue.
This rudimentary vasoformative architecture is clearly demonstrated with reticulin staining (Figure 2).
Since epithelioid hemangioendotheliomas and angiosarcomas may express cytokeratins, even if a vasoformative tumor is keratin positive, the tumor should be stained with vascular markers.
The tumor typically shows features of angiosarcoma including vasoformative architecture with hobnailed appearance (Figure 3) and it has infiltrative margins.
This case also showed a transition to a higher-grade tumor, which was vaguely vasoformative and mitotically active, suggesting progression to an EA.
The cytologic appearance can be epithelioid, spindled, or pleomorphic (Figure 6, A through C), while the architecture can be vasoformative, sievelike, kaposiform, or solid (Figure 7, A through D).
They suggest that in VPTR, the significant proliferative activity is astrocytic and that, presumably, the vascular component is secondary to the release of vasoformative factors by the glial cells.
