A '''hemangioma''' is a benign tumor of [[blood vessels]], often appearing as a red to purple raised lesion on the skin. These lesions are most commonly found in infants and are known for their rapid growth during the first year of life, followed by a slow involution phase.

== Introduction ==
== Signs and Symptoms ==
A [[hemangioma]] represents a typically benign [[vascular tumor]] stemming from blood vessel cell types. Among the myriad of types, the most prevalent form is the infantile hemangioma, colloquially known as a "[[strawberry mark]]", primarily noticeable on the skin at birth or during the initial weeks of life. While a hemangioma can surface anywhere on the body, they are predominantly seen on the face, scalp, chest, or back. Ordinarily, treatment for a hemangioma is not required unless it obstructs vision or respiration, or in rare cases where an internal hemangioma leads to or exacerbates other medical conditions.
Hemangiomas typically present as a red to purple raised lesion on the skin. They can vary in size and may appear anywhere on the body, but are most commonly found on the face, scalp, chest, or back. While most hemangiomas are superficial, some may have a deeper component, leading to a bluish hue.


== Types of Hemangioma ==
== Complications ==
Although hemangiomas are generally benign, they can lead to complications such as [[ulceration]], [[bleeding]], and [[infection]]. In rare cases, they may interfere with vital functions if located near the eyes, nose, or mouth.


Hemangiomas are [[benign tumors]] of the vascular system, exhibiting various types and forms. The International Society for the Study of Vascular Anomalies (ISSVA) continually revises the terminology for these hemangioma types, improving the understanding and classification of these conditions.
== Causes ==
The exact cause of hemangiomas is not well understood, but they are believed to result from [[genetic factors]]. Certain risk factors, such as [[premature birth]] and [[female gender]], have been associated with a higher incidence of hemangiomas.


=== Infantile Hemangioma ===
== Diagnosis ==
Diagnosis of hemangiomas is primarily based on [[physical examination]]. In some cases, [[imaging studies]] such as [[ultrasound]] or [[MRI]] may be used to assess the extent of deeper lesions.


[[Infantile hemangioma]] is the most common type of vascular birthmark. This benign vascular tumor often appears during the first or second week of life as a faint red stain or patch, rapidly growing for up to 6-9 months before it begins to slowly regress, typically disappearing by the time the child is ten years old.
== Treatment ==
 
Most hemangiomas do not require treatment and will resolve on their own by age 10. However, in cases where treatment is necessary, options include [[observation]], [[beta-blockers]] such as [[propranolol]], and [[laser therapy]].
=== Congenital Hemangioma ===
 
[[Congenital hemangioma]]s are fully formed at birth, unlike infantile hemangiomas which proliferate after birth. These vascular lesions can be categorized into rapidly involuting congenital hemangiomas (RICH) which resolve spontaneously within the first year of life, and non-involuting congenital hemangiomas (NICH) which do not involute but remain static in size.
 
==== Cavernous Liver Hemangioma ====


A [[cavernous liver hemangioma]] is a subtype of hemangioma that occurs in the liver. These are typically asymptomatic and are most often discovered incidentally during imaging for unrelated conditions.
== Prognosis ==
The prognosis for hemangiomas is generally excellent, with most lesions resolving completely by age 10. However, some may leave residual skin changes or scarring.


== Diagnosis ==

* [[Vascular tumor]]
The diagnosis of a hemangioma often involves a thorough clinical evaluation, detailed patient history, and specialized tests or procedures such as [[ultrasonography]], [[MRI]]s, or [[biopsies]], if necessary. The exact diagnostic processes can vary depending upon the type and location of the hemangioma.

== Treatment ==


Treatment of hemangiomas is typically not required unless they interfere with vital functions or pose potential risks. When intervention is necessary, treatment options may include medication, laser therapy, surgical removal, or in some cases, a combination of these approaches. Topical or oral [[beta blockers]], such as propranolol, have emerged as first-line treatment for problematic infantile hemangiomas. Other therapies for severe cases might include corticosteroids, vincristine, or interferon.

Hemangiomas, while benign, can create functional and cosmetic concerns depending on their size, location, and rate of growth. Although most hemangiomas resolve naturally, some require medical intervention. Ongoing advancements in the understanding and treatment of these vascular anomalies continue to improve the prognosis for affected individuals.

A hemangioma is a benign tumor of blood vessels, often appearing as a red to purple raised lesion on the skin. These lesions are most commonly found in infants and are known for their rapid growth during the first year of life, followed by a slow involution phase.

Signs and Symptoms

Hemangiomas typically present as a red to purple raised lesion on the skin. They can vary in size and may appear anywhere on the body, but are most commonly found on the face, scalp, chest, or back. While most hemangiomas are superficial, some may have a deeper component, leading to a bluish hue.

Complications

Although hemangiomas are generally benign, they can lead to complications such as ulceration, bleeding, and infection. In rare cases, they may interfere with vital functions if located near the eyes, nose, or mouth.

Causes

The exact cause of hemangiomas is not well understood, but they are believed to result from genetic factors. Certain risk factors, such as premature birth and female gender, have been associated with a higher incidence of hemangiomas.

Diagnosis

Diagnosis of hemangiomas is primarily based on physical examination. In some cases, imaging studies such as ultrasound or MRI may be used to assess the extent of deeper lesions.

Treatment

Most hemangiomas do not require treatment and will resolve on their own by age 10. However, in cases where treatment is necessary, options include observation, beta-blockers such as propranolol, and laser therapy.

Prognosis

The prognosis for hemangiomas is generally excellent, with most lesions resolving completely by age 10. However, some may leave residual skin changes or scarring.
