Vascular Anomalies Clinic, Pediatric Surgery Program at Johns Hopkins All Children's Hospital

We treat patients with a range of vascular conditions and birthmarks, from simple and benign to rare and complex. These include vascular tumors, vascular malformations, overgrowth syndromes and mixed malformations.

Conditions We Treat in the Vascular Anomalies Clinic at Johns Hopkins All Children’s

Vascular tumors occur when blood vessels grow abnormally, forming a mass, or tumor. The tumor may be on the surface of the skin, under the skin or both. Many vascular tumors can be diagnosed during a physical exam. Your child’s physician will sometimes order an ultrasound, X-ray or MRI to help diagnose a vascular tumor, depending on your child’s individual needs.

Vascular tumors we treat include:

  • Angiosarcoma
  • Congenital hemangiomas
  • Epithelioid hemangioma
  • Epithelioid hemangioendothelioma
  • Infantile hemangiomas (sometimes called a “strawberry birthmark”)
  • Kaposiform hemangioendothelioma
  • Papillary intralymphatic angioendothelioma (PILA)
  • Pyogenic granuloma
  • Retiform, pseudomyogenic and composite hemangioendothelioma
  • Spindle cell hemangioma
  • Tufted angioma

Vascular malformations occur when blood vessels do not form properly while a baby is developing in the uterus. The symptoms of these conditions vary depending on the type of blood vessels involved. These may include arteries, veins, capillaries, lymphatic channels or a combination of these. Though they are present at birth, they are often noticed for the first time later in childhood or after puberty.

  • Parkes Weber syndrome
  • Sporadic arteriovenous malformations

Capillary malformations

  • Cutaneous, reticulate, and/or mucosal CM
  • Cutis marmorata telangiectatica congenital (CMTC)
  • Diffuse capillary malformation with overgrowth (DCMO)
  • Sturge-Webber Syndrome
  • Telangiectasias

Lymphatic malformations

  • Generalized lymphatic anomaly (GLA)
  • Gorham-Stout disease (GSD)
  • Kaposiform lymphangiomatosis (KLA)
