VASCULAR LESION IN NEWBORN/INFANT (1st month of life)

The ISSVA (International Society for the Study of Vascular Anomalies) is a good reference for classification of vascular lesions in infants. Their classification for vascular anomalies may be found here.

Congenital Malformations

The term capillary malformation usually refers to the port wine stain but may apply to the nevus simplex.

An arterio-venous malformation may occur.

Congenital Vascular Tumors

Congenital hemangiomas are fully formed at birth and exhibit very little if any post natal growth. The two are RICH and NICH. Glucose transporter-1 protein (Glut-1) staining is characteristic of infantile hemangiomas, but is absent RICH and NICH. Rarely, there are some hemangiomas that start off involuting, but then stop. These are partially involuting hemangiomas. They tend to stabilize after 12-30 months of life. They may occur anywhere. JAAD Jan 2014
