A spider angioma, also known as nevus araneus or spider nevus, is the most common telangiectasia of childhood. It is composed of a central arteriole with numerous radiating telangiectasias. Lesions are never present at birth but may arise spontaneously at any time after age 2 years. The etiology in children is unknown, although trauma and sun exposure are hypothesized to play a role in their development. It is estimated that 50% of spider angiomas will spontaneously regress by adulthood.
