Vascular anomalies have been divided by medical experts into two main groups: tumors and malformations. Generally, vascular tumors are proliferative (i.e. growing or multiplying), while vascular malformations enlarge through expansion of a developmental anomaly without underlying proliferation. Vascular tumors in children, outside of hemangiomas, are rare.

There are different types of vascular tumors:

Pyogenic granuloma – These vascular tumors are always benign, but they can be a concern. These skin growths contain a very large number of blood vessels, contributing to their red color. Sometimes these tumors will bleed, and they do cause cosmetic concerns to many who are affected. These skin growths mainly affect children, young adults, and often occur during pregnancy. This vascular tumor starts off as a lesion with a rapid growth period, becoming raised and very red. Because these tumors often occur on the face and around the eyes, they must be watched closely to ensure that they do not damage vision.

RICH, NICH – Congenital hemangiomas are rare, benign vascular tumors that are present and fully grown at birth. They present as bossed plaques or exophytic masses located on the head, neck, or limb. The type of congenital hemangioma cannot be determined immediately; thus, parents and doctors must wait to see if one goes away or does not. These vascular abnormalities are benign and often need no treatment. However, a NICH (non-involuting congenital hemangioma) may be surgically removed. If the NICH is large, embolization may need to be performed in order to control the bleeding during surgery.

Kaposiform hemangioendothelioma – This is a rare, locally aggressive vascular tumor of the skin, deep soft tissue, and bone in children. It is a benign tumor of a child’s blood vessels that can appear anywhere on the body. While this type of tumor is benign, it can grow and it requires specialized treatment because of the specific complications that are present with this vascular tumor.

For more than 20 years, Dr. Milton Waner has restricted his practice to the treatment of hemangiomas and vascular tumors and malformations. Working as an interdisciplinary team with a team of highly skilled field experts, The Vascular Birthmark Institute of New York is the go-to clinic for difficult cases and effective treatment. If your child has a vascular tumor, please contact us today. Our mission is to provide world-class care.
