Cellular Angiofibroma



Cellular Angiofibroma


Elizabeth A. Montgomery, MD









At low magnification, this cellular angiofibroma is well marginated but unencapsulated. Note the prominent vessels, readily apparent even at scanning magnification.






Thick hyalinized vessels are characteristic of cellular angiofibroma. The lesion is moderately cellular and consists of a uniform population of spindle cells and background collagen fibrils.
