Spider angioma, also known as spider nevus or spider telangiectasia, is a common vascular lesion that appears as a red spot with small blood vessels radiating outwards, resembling a spider’s web. Spider angioma is a benign skin condition characterized by the presence of a central red spot, known as the arteriole, from which small blood vessels branch out in a spider-like pattern. These abnormal blood vessels are usually found on the face, neck, arms, or upper body. Spider angioma is primarily caused by the dilation of small blood vessels near the surface of the skin. While the exact cause remains unclear, there are several factors that may contribute to its development. These include hormonal changes, liver disease (such as cirrhosis), increased estrogen levels (as in pregnancy or certain hormonal disorders), sun exposure, and a family history of spider angioma.
Types
Types of Spider Angioma:
- Classic Spider Angioma: The classic spider angioma presents as a red lesion with a central arteriole and radiating capillaries, resembling a spider or spider web. These lesions are commonly found on the face, neck, upper trunk, and arms. Classic spider angiomas are often associated with liver disease or hormonal imbalances.
- Simple Spider Angioma: Simple spider angiomas are similar to the classic type in appearance, but they lack the central arteriole. These lesions consist of a central red spot with radiating capillaries, giving them a spider-like appearance. Simple spider angiomas can occur anywhere on the body and are not typically linked to any underlying medical conditions.
- Rapidly Involuting Congenital Hemangioma (RICH): Rapidly involuting congenital hemangiomas (RICH) are a type of vascular birthmark that may resemble spider angiomas during their early stages. RICH lesions are typically present at birth or appear shortly after and gradually fade away over time. Unlike true spider angiomas, RICH lesions do not involve an arteriole in the center.
- Nevus Flammeus (Port-Wine Stain): Nevus flammeus, commonly known as a port-wine stain, is a type of birthmark that may resemble a spider angioma due to its red coloration. However, port-wine stains do not exhibit the characteristic spider-like branching pattern. These birthmarks are caused by abnormal blood vessel development and can vary in size and shape.
