Hemangiomas, or infantile hemangiomas, are noncancerous growths of blood vessels. They’re the most common growths or tumors in children. They usually grow for a period of time and then subside without treatment.

They don’t cause problems in most infants. However, some hemangiomas may open and bleed or ulcerate. This may be painful. Depending on their size and location, they may be disfiguring. Additionally, they may occur with other central nervous system or spine abnormalities.

The growths may also occur with other internal hemangiomas. These affect internal organs such as:

the liver
other parts of the gastrointestinal system
the brain
organs of the respiratory system
Hemangiomas that affect organs usually don’t cause problems.

Vascular anomalies are abnormalities or disorders of the vascular system, either in veins or arteries. Vascular anomalies are classified as either a vascular tumor or a vascular malformation. Blood is pumped through the body in tube-like structures called blood vessels. These vessels form a network.

A hemangioma (he-man-jee-O-muh) is a bright red birthmark that shows up at birth or in the first or second week of life. It looks like a rubbery bump and is made up of extra blood vessels in the skin.

5-year-old undergoes lifesaving surgery to remove massive growth on face, neck A 5-year-old from Ethiopia who underwent a 12-hour surgery in New York last month is breathing easier after doctors removed a life-threatening growth from her face and neck.

“Background
PIK3CA-related disorders include vascular malformations and overgrowth of various tissues that are caused by postzygotic, somatic variants in the gene encoding phosphatidylinositol-3-kinase (PI3K) catalytic subunit alpha. These mutations result in activation of the PI3K/AKT/mTOR signaling pathway. The goals of this review are to provide education on the underlying mechanism of disease for this group of rare conditions and to summarize recent advancements in the understanding of, as well as current and emerging treatment options for PIK3CA-related disorders.”

A hemangioma can occur anywhere on the body, but most commonly appears on the face, scalp, chest or back. Treatment for a baby's hemangioma (infantile hemangioma) usually isn't needed as it fades over time. A child who has this condition during infancy usually has little visible trace of the growth by age 10. You may want to consider treatment if a hemangioma interferes with seeing, breathing or other functions.”

Vascular Anomalies Include Vascular Tumors & Vascular Malformations.
Vascular Anomalies are comprised of tumors and malformations. These lesions result from abnormally developed blood vessels. The abnormalities may occur in the arteries, veins, capillaries or lymphatic vessels. The classification of vascular anomalies is complex. A listing of some of the different types of anomalies is below.
Vascular Tumors
Benign vascular tumors- Infantile Hemangioma (IH), Congenital Hemangioma (CH), Tufted Angioma, Spindle Cell Angioma, Epithelioid Hemangioma, Pyogenic Granuloma, other
Locally aggressive or borderine vascular tumors- Kaposiform hemangiomaendothelioma (KHE), retiform hemangioendothelioma, Papilary intralymphatic angioendothelioma (PILA), Kaposi Sarcoma, others
Malignant vascular tumors- Angiosarcoma, Epithelioid hemangioendothelioma, others
Infantile Hemangioma is the most common benign vascular tumor of infancy and children. It presents in a pattern of either focal, multifocal, segmental or indeterminate. There are different types of infantile hemangioma: superficial, deep, mixed (superficial + deep), reticular/abortive/minimal growth and others. Infantile Hemangioma may be associated with other lesions.
PHACE Syndrome is an association of other anomalies with an infantile hemangioma. P-posterior fossa malformations, H- hemangioma, A- araterial anomalies, C- cardiovascualr anomalies, E- eye anomalies, sternal clefting and or supraumbilical raphe.
Lumbar Sacral Pelvis Syndrome is an association of lower body hemangioma, urogenical anomalies, ulceration, myelopathy, bony deformities, anorectal malformations, arterial anomalies and renal anomalies.
Vascular Malformations – Include simple and combined vascular malformations. Some are named of major vessels and others are associated with other anomalies.
Simple Vascular Malformations:
Capillary Malformations
Venous Malformations
Arteriovenous Malformations
Lymphatic Malformations
Arteriovenous Fistula
Combined Vascular Malformations:
Capillary-Venous Malformation
Capillary Lymphatic Malformation
Capillary Arteriovenous Malformation
Lymphatic Venous Malformation
Capillary Lymphatic Venous Malformation

Named for Major Vessels

Servelle Martorell Syndrome
Sturge Weber Syndrome
Maffucci Syndrome

Classification of Vascular Anomalies was first published by Dr. John Mulliken in 1981, it has recently been revised at the 2020. The information above is from this newly revised classification.

Types of vascular anomalies include:

Hemangiomas:(infantile and congenital)
Pyogenic granulomas: (lobular capillary hemangiomas)
Glomangiomas: (glomus cell tumor)
Kaposi’s sarcoma
Angiosarcoma
Hemangioendotheliomas:(Kaposiform hemangioendothelioma)

Vascular malformations:
Vascular malformations are present at birth, though they may not be obvious for several years. They are often named according to the type of blood vessel that is most affected.

Types of vascular malformations include:

Capillary vascular malformations: (port-wine stains)
Arterial malformations: (abnormal arteries)
Venous malformations: (abnormal veins)
Arteriovenous malformations: (abnormal arteries and veins)
Lymphatic malformations: (abnormal lymphatics, or lymph vessels, which can lead to enlarged water-filled cysts and swelling)
Spider angiomas: (arteries that show on the surface of the skin with a central red dot and outer branches)
Angiofibromas :(pink, raised skin bumps seen in patients with tuberous sclerosis, formerly called adenoma sebaceum)

Complex combined malformations: (sometimes accompanying a genetic syndrome), including:

Sturge-Weber syndrome (port wine stain in the upper third of the face, with eye and central nervous system involvement)

Klippel-Trenaunay syndrome (abnormal capillaries, veins, and lymphatics with overgrowth of the involved area of the body)

Parkes-Weber syndrome (port wine stain with arteriovenous malformation and overgrowth of the involved area of the body)

Hereditary hemorrhagic telangiectasia (may have nose and GI bleeding from small dilated vessels)

CLOVES syndrome (a collection of conditions that may include congenital lipomatous overgrowth, vascular malformations, epidermal moles, and spinal abnormalities)

Proteus syndrome (vascular malformations and overgrowth of body parts)
