Hemangioma, multiple (Hemangiomatosis of the spleen)


Microscopic Description:
Within the spleen, there are multiple localized and well circumscribed collections of dilated thin-walled blood vessels. In between these nodules is normal splenic parenchyma. The vessels are lined by thin simple endothelial cells which are CD31 positive. There is no atypia noted. Hobnailing and detachment into several lumens, which is characteristic of the littoral cell hemangioma, is not evident.
