The terminology used to define, describe, and categorize vascular tumors and malformations has changed over time. The term hemangioma was originally used to describe any vascular tumor-like structure, whether it was present at or around birth or appeared later in life. In 1982, Mulliken and Glowacki proposed a new classification system for vascular anomalies which has been widely accepted and adopted by the International Society for the Study of Vascular Anomalies. This classification system was recently updated in 2015. The classification of vascular anomalies is now based upon cellular features, natural history, and clinical behavior of the lesion. Vascular anomalies are divided into vascular tumors/neoplasms which include<unk> s, and vascular malformations that include entities with enlarged or abnormal vessels such as capillary malformations (port wine stains), venous malformations, and lymphatic malformations. In 2000, GLUT-1, a specific immunohistochemical marker, was found to be positive in<unk> s and negative in other vascular tumors or malformations. This marker has revolutionized the ability to distinguish between<unk>  and other vascular anomalies.
