Capillary Hemangiomas
Cavernous Hemangiomas. Microscopic and immunohistochemical findings of the tumor. (A) Photomicrographs of the extraosseous fraction of the lesion showing numerous vascular channels and spaces (hematoxylin and eosin; original magnification, ×200) (B) Intraosseous fraction showing multiple tiny fragments of trabecular bone and irregularly-shaped marrow spaces being replaced by thin-walled capillary hemangioma (hematoxylin and eosin; original magnification, ×200). Immunohistochemical analysis showing that the tumor was positive for (C) cluster of differentiation 31 and (D) vimentin, but negative for (E) epithelial membrane antigen (original magnification, ×200).

The pathology of capillary hemangiomas is:

-Etiology: The cause of capillary hemangiomas is hamartomatous proliferations

-Genes involved: Unknown.

-Pathogenesis: The sequence of events that lead to capillary hemangiomas, thought to result from vascular endothelial cells hamartomatous propagations.

-Morphology: The morphology associated with capillary hemangiomas shows varying in size, bright red to blue, and slightly raised lesion.
