How do vascular malformations typically present?

Vascular malformations are abnormal structures in the blood vessels that arise during embryonic development, which means that they are typically congenital rather than acquired later in life. These malformations can manifest on various parts of the body, including the skin, muscles, and internal organs, making them versatile in location. As a result, the correct option accurately reflects the characteristic that vascular malformations can indeed occur anywhere on the body, affecting individuals regardless of age or site. This wide distribution highlights their nature as developmental anomalies rather than acquired lesions or injuries. Understanding this aspect is crucial for diagnosing and managing patients with vascular malformations effectively.
