Vascular skin problems are often caused by issues with the vascular, or circulatory, system. The skin, also called the dermis, is one of the largest organs in the human body, and it is laced with capillaries that transport nutrients and oxygen in the blood. In some individuals, problems with blood flow or the amount of oxygen in the blood causes certain skin conditions. Understanding a few of these conditions and what causes them will help you identify potential problems so you can seek appropriate treatment.
Angiomas are a common vascular skin condition caused by a profusion of blood vessels in the skin layers that are often called spider veins. The angiomas are created by over-development of cells that line blood vessels, states DermNetNZ.org. Cherry angiomas look like dark red or purplish round spots often seen on the torso. Some cherry angiomas look like a red pinprick, while others may look more like a reddish mole. Spider angiomas look like a cherry angioma, except they have telltale red lines radiating outward from the center of the angioma, and are commonly found on the face.
Believed to be caused by smoking, Buerger disease is a condition caused by poor oxygenation in blood cells that leads to the formation of tiny clots. Clots formed by this condition are typically found in small arteries of the hands and feet.
Birthmarks are commonly found on babies, and can appear in different colors ranging from pink to brown to blue. Birthmarks can be found anywhere on the body as a result of a high number of blood vessels in the skin that create a darkened area from the size of a pencil eraser to a piece of notebook paper. Also commonly known as port wine stains, flat stains or hemangiomas, birthmarks don't cause any harm, according to the American Academy of Dermatology.
Rosacea is a relatively common vascular skin problem that mostly afflicts individuals with fair skin and blue eyes, states DermNetNZ.org. While exact causes of the condition are currently undefined, the flush or blush that often occurs on the cheeks, forehead, nose and chin is caused by prominent blood vessels found near the surface of the skin that may be accompanied by papules and sometimes tuberous growth on the nose.
Stasis dermatitis is a condition caused by inadequate circulation of deoxygenated blood back to the heart, which causes a rash on the lower limbs. In such cases, the inner leg shows more signs of rash than the outer leg. The rash is commonly presents with swelling, or edema. In some cases, the rash may develop into ulcerous lesions.
