Cirsoid aneurysm
A cirsoid aneurysm, also referred to as an arteriovenous hemangioma[1] is the dilation of a group of blood vessels due to congenital malformations with arterio venous (AV) shunting. "Cirsoid" means resembling a varix.[citation needed] They are most common on the head or neck.[2]
Cirsoid aneurysms appear as nodules or papules. Histologically, they are composed of both thick- and thin-walled blood vessels.[2]
