What Is a Venous Angioma?

Venous hemangiomas are vascular lesions with highly dilated veins. Extremities and brain tissue are more common. When it occurs on the skin, the skin damage is generally small, and it is an isolated purple to red patch or nodule, which gradually increases without obvious symptoms; if it occurs in the cerebral blood vessels, it can cause sudden pathological death due to rupture and bleeding. Its formation mechanism is that many abnormally dilated veins are collected into a central drainage vein, and the central vein drains to the cerebral cortex veins, subventricular veins, or directly to the adjacent dural sinus. Under the microscope, it can be seen that the malformed blood vessel is a vein, and the tube wall has few smooth muscles and elastic fibers. The tube wall can also be thickened, fibrous and calcified and thickened. If in the brain, there is normal brain tissue between venous hemangioma tissues; often collapsed veins and narrow fissures, with little or no infiltration of inflammatory cells. ^[1]

It usually presents as a single dark red pimples or nodules, and most lesions are less than 1 cm in diameter. Common on the face, followed by limbs.

Dark red papules or nodules are found clinically, but pathological examination must be performed to confirm the diagnosis. It can be considered that vascular tumors are not difficult to diagnose because of pathological changes.

Skin lesions are small and superficial, and can be treated with freezing and electrocoagulation.
