  Hemangiomas, colloquially termed „strawberry marks”, are the most common benign tumor of infancy and are caused by endothelial cell proliferation. Congenital hemangiomas are visible at birth whereas infantile hemangiomas appear later. […] Infantile hemangiomas become clinically apparent within 1 to 4 weeks. The localization is ubiquitous, and they may occur on the skin and mucosal surfaces. The majority present as a single localized cutaneous hemangioma but infantile hemangioma may be multifocal or segmental. Hemangiomas occur most commonly on the head and the neck and are seen in 60 % of cases. This is followed by lesions on the trunk in 25% of cases, and least commonly, on the extremities, seen in 15% of cases. […] The natural history of infantile hemangioma has a triphasic evolution: Early proliferative or growth phase: Usually, there is rapid growth during the first three months and gradual growth in months five to eight of life.

  Hemangiomas are connected to the circulation and their appearance depends on whereabouts in our body they occur. […] When present on the skin surface, they often resemble the surface of a strawberry and these skin lesions are sometimes referred to as strawberry hemangiomas. […] If a hemangioma occurs just beneath the skin, it may appear as a bluish swelling. […] On first appearance, a hemangioma may be mistaken for a scratch or a bruise but their diagnosis is confirmed once the tumors grow and become larger. […] Superficial hemangiomas eventually form a raised, red area of skin supplied with its own blood vessels, which can make the tumor feel warm to the touch. […] If the hemangioma is present beneath the skin as a deep hemangioma, it appears bluish in color due to the blood vessels also being deeper down in the skin. These deep hemangiomas are sometimes not obvious for the first few weeks of life and only form a visible lump after growing for a period. […] Most children only ever develop one haemangioma but occasionally a child develops multiple hemangiomas that affect various different body parts. This condition is more common among children born as part of a multiple birth.

  https://www.mayoclinic.org/diseases-conditions/hemangioma/symptoms-causes/syc-20352334

  A hemangioma may be visible at birth, but it appears more often during the first month of life. It starts as a flat red mark on the body, most often on the face, scalp, chest or back. A child generally only has one mark, but some children may have more than one mark. […] During your child’s first year, the red mark may grow rapidly into a spongy, rubbery-looking bump that sticks out from the skin. The hemangioma then enters a rest phase. Then it will begin to slowly go away. […] Many hemangiomas go away by age 5, and most go away by age 10. The skin may be slightly discolored or raised after the hemangioma goes away.

  Infantile hemangiomas are benign vascular neoplasms that have a characteristic clinical course marked by early proliferation and followed by spontaneous involution. […] Superficial cutaneous hemangiomas progress sequentially through the following stages: Blanching of the involved skin, Occasionally (especially with lip and buttock lesions), a shallow ulceration, Fine telangiectasias, A red or crimson macule or papule, often surrounded by a faint halo of vascular blanching. […] Infantile hemangiomas characteristically exhibit early rapid growth followed by slow involution, as follows: Rapid growth during the neonatal period (birth to 4 wk) is the historical hallmark of infantile hemangiomas, The hemangioma becomes elevated and dome shaped, lobulated, plaquelike, tumoral, or any combination of these morphologies, The most growth occurs during the first 4-6 months of life, Proliferation slows considerably between 6-12 months of life, Complete involution in 50% of infantile hemangiomas by age 5 years and 70% by age 7 years, Complete involution may take an additional 3-5 years in the remainder. […] The prognosis for most uncomplicated infantile hemangiomas is very good, with complete involution of 50% by age 5 years, 70% by age 7 years, and 90% by age 9 years. Despite resolution of the vascular component, residual skin changes are observed in roughly 50% of cases.

  https://www.texaschildrens.org/content/conditions/hemangioma

  Hemangiomas are benign (not cancer) growths of extra blood vessels in the skin and are one of the most common skin conditions seen in children in the first year of life. About 5% of all children will develop a hemangioma. […] Most often hemangiomas appear during the first one to four weeks after birth. Hemangiomas usually grow most in the first 3-4 months of life. Later, generally around 6 to 18 months of age, they begin to very slowly improve, a process called involution. Most hemangiomas have started to involute significantly between 1 and 3 years of age, and many are much better or hard to notice by the time a child starts kindergarten. […] Especially during infancy, hemangiomas may feel warm to the touch. They will also commonly change in appearance, temporarily, with a child’s body temperature, so may be more noticeable and look bigger in a warm bath or with crying. While parents often worry about the possibility that a hemangioma will bleed, significant bleeding is very rare. Hemangiomas occur in the skin and rarely affect any part of the body underneath. They are not painful unless they ulcerate. Ulceration is a complication when a small scab or sore appears on the hemangioma. This is most likely to happen early in the first year, during the rapid growth period, and especially when a hemangioma is in a location of pressure or trauma (like the back, back of the scalp, diaper area, or lip).

  Hemangiomas generally appear as red to purplish-blue marks or bumps, on or under the skin. They usually tend to be redder on light skin and more purple on dark skin. […] Hemangiomas often develop in newborn babies and go away again on their own in the first few years of life. […] Hemangiomas then go through three phases: Proliferation (growth), Plateau, and Involution. […] Hemangiomas disappear in about 80 to 90% of children by the age of four. But this can take up to ten years for large hemangiomas. […] In adults, hemangiomas usually start to appear after the age of 30 and remain a few millimeters in size, but dont go away again. […] Hemangiomas dont normally cause any pain or other symptoms. But larger hemangiomas in very visible places (like the face) can attract attention and sometimes unpleasant comments, too.

• #1 Infantile haemangioma: Definition and pathogenesis

  https://dermnetnz.org/topics/infantile-haemangioma-definition-and-pathogenesis

  Infantile haemangiomas are typically solitary and most are located on the head and neck region (60%). Involvement of internal organs is usually indicated by multiple cutaneous lesions. The clinical features are determined by the depth of the lesion, distribution pattern, and phase of growth. […] Most infantile haemangiomas show rapid growth in the first 3 months with a growth arrest by about 5 months of age, receding subsequently over several years. The progression may be described in different morphological phases. […] The bright red colour changes to a dull grey surface associated with flattening, softening, and shrinking from the centre towards the periphery. While a grey stage is suggestive of involutional change, a white infantile haemangioma may be a sign of impending ulceration. The most rapid phase of involution is seen between 14 years and approximately 50% of lesions involute by 5 years, 70% by 7 years, and 90% by 9 years of age.

  The prognosis is very good for uncomplicated IH and there is complete involution in the majority of cases. 50% of hemangiomas will resolve in 5 years, 70% by 7 years and 90% by 9 years. Approximately 8% of IH leave cosmetic disfigurement and require some intervention. […] The complications depend on the patient’s age and on the hemangioma’s size and location. The complications of IH are listed below. Ulceration is the most common complication and occurs in up to 10% of cases. Locations with higher risk of ulceration include the anogenital area, lower lip, axilla, and neck.

  https://www.paulcmccormick.com/condition/hemangioma/

  Symptoms vary depending on the size and location of the tumor; most hemangiomas cause no symptoms at all. […] Among symptomatic hemangiomas, the most common symptom is pain at the tumor site, usually in the back. If the tumor expands beyond the bony boundaries or causes collapse of a vertebra it will create pressure on the surrounding nerves or spinal cord. This can lead to pain that radiates to the arms or legs, weakness, numbness, or clumsiness of the arms or legs, or compromised bowel and/or bladder control. […] A vertebra weakened by a hemangioma may collapse, a painful event known as a compression fracture. Hemangiomas may also bleed, causing a hemorrhage that can expand and compress the nerves or spinal cord.

[…] Most often flush with the skin or slightly elevated, but sometimes they grow from a stalk. […] […] […] Deep hemangiomas in muscle may cause pain, as well as swelling around the hemangioma that increases with activity. […] Hemangiomas in bones may cause pain and enlargement of the bone. […] […] […] Common infantile hemangiomas follow the same growth pattern: a period of rapid growth, often during the first year, followed by a period of tumor shrinkage (called involution or regression). […] Most infantile hemangiomas will completely regress (shrink) on their own and require no treatment. […] The timeframe for rapid growth and then involution varies greatly, but most infantile hemangiomas have finished involution by the time the child reaches puberty.

  https://www.healthline.com/health/hemangioma

  Hemangiomas, or infantile hemangiomas, are noncancerous growths of blood vessels. They typically go away on their own, but a doctor may treat them if they open or become sores. […] They usually grow for a period of time and then subside without treatment. […] However, some hemangiomas may open and bleed or ulcerate. This may be painful. Depending on their size and location, they may be disfiguring. […] Depending on the location and size, hemangiomas dont normally cause symptoms during or after their formation. However, they may cause some symptoms if they grow large or in a sensitive area or if there are multiple hemangiomas. […] Hemangiomas of the skin usually appear as small red scratches or bumps. As they grow, they look like burgundy-colored birthmarks. […] Hemangiomas inside the body present with symptoms specific to the organ thats affected. For example, a hemangioma affecting the gastrointestinal tract or liver may present with symptoms such as nausea, vomiting, abdominal discomfort, loss of appetite, and a feeling of fullness in the abdomen. […] Hemangiomas within the body may require treatment if they grow too large or cause pain.

  Hemangiomas usually appear in the first six months. They can be red to reddish-purple, raised lesions on the skin. They can also be large, raised lesions with visible blood vessels. Typically, parents notice a spot on a babys skin that grows in size and color. […] Hemangiomas that involve the eye can cause serious eye problems. If large and unchecked, they can lead to poor vision development from amblyopia or „lazy eye.” Hemangiomas around the eye can also cause glaucoma. Hemangiomas in the eye socket can press on the optic nerve. This can cause optic nerve atrophy and lead to vision loss. […] Hemangiomas gradually disappear over time. Half of hemangiomas disappear by age five, and 90 percent (9 out of 10) are gone by age nine.

  Hemangiomas can grow within the blood vessel layer beneath the retina called the choroid. If they are located in the macula (center of vision) or they leak fluid (which causes a retinal detachment or cystic changes in the retina), they can affect visual acuity. […] By lifting the overlying retina, choroidal hemangiomas can cause far-sightedness (hyperopia), distorted vision (metamorphopsia), flashing lights, or blurred vision. Choroidal hemangioma that cause no symptoms at all, are usually found on routine dilated eye examinations (ophthalmoscopy). […] Choroidal hemangioma can be stable and not require treatment. Others can change a patient’s vision by displacing the retina causing hyperopia (far-sightedness), causing degeneration of the overlying retina (cystoid degeneration), or by leaking fluid under and detaching the retina (serous retinal detachment).

  A hemangioma is a noncancerous liver tumor composed of a mass of abnormal blood vessels. […] In the United States, up to about 20% of adults (mostly women) have small hemangiomas that cause no symptoms. […] Hemangiomas that cause symptoms are very rare. Symptoms are more likely if hemangiomas are larger than about 1 inches (4 cm). These tumors may cause abdominal discomfort and bloating and, less often, loss of appetite, nausea, a feeling of being full after eating a small meal, or pain. […] In infants, hemangiomas usually disappear on their own. However, occasionally large hemangiomas cause problems, such as widespread blood clotting and heart failure. These tumors require treatment, which may include medications (such as corticosteroids and other immunotherapy agents), a procedure to block the hemangiomas blood supply (called selective hepatic artery embolization), sometimes surgery to remove the hemangioma, and, rarely, liver transplantation.

  Vertebral hemangiomas are common benign vascular tumors of the spine. They have a prevalence of 10-12% in the general population and account for 2-3% of all spinal tumors. Most are asymptomatic and discovered incidentally on either an MRI or CT scan. […] Only 0.9-1.2 % of all vertebral hemangiomas expand and become symptomatic. Pain and nerve compression of nerves and spinal cord are common symptoms. […] Most vertebral hemangiomas are asymptomatic and cause no symptoms. […] The most common symptoms include: Back pain can occur in patients with vertebral hemangiomas with varying intensity from mild to moderately severe. The pain is thought to be due to bleeding, boney expansion secondary to tumor growth or compression fracture. […] If the vertebral hemangioma grows, it can extend beyond the bone and encroach upon the spinal canal with irritation or compression of spinal nerves and or the spinal cord. This nerve compression can result in numbness in the thoracic region or lower extremities.

  Spinal hemangiomas, most frequently found in the mid and lower back, are one of the most common tumors affecting the spine. While they usually do not cause symptoms, they can lead to considerable discomfort and issues with the nervous system. […] In a small percentage of people, spinal hemangiomas can progress beyond non-symptomatic growths and lead to significant pain and a range of symptoms affecting the back’s nerves. […] While most spinal hemangiomas are asymptomatic and go unnoticed, symptoms arise when the tumor puts pressure on nearby nerves or the spinal cord. […] When symptoms do occur, you may experience: Severe back pain, often worsening with activity; Numbness, weakness, or coordination problems in the arms or legs; Difficulties with bladder or bowel control. […] If left untreated, they can eventually lead to neurological damage, a loss of range of motion, and even paralysis.

  Spinal hemangiomas are benign (noncancerous) tumors that develop from the blood vessels. The vast majority are asymptomatic, but in some cases, they can cause pain and neurological issues. […] When spinal hemangiomas display symptoms, the symptoms tend to be the same as those of other spine conditions. Spinal hemangiomas may cause back pain where they are located. They can also cause pain or discomfort that radiates along a nerve. This is due to the pressure being placed on that nerve or inflammation from the tumor irritating adjacent tissues. This pain can occur along your arms or legs, or in other areas of your body. […] There is also the potential for spinal cord compression, which causes pain, weakness in one or more extremities, and numbness or tingling. If the hemangioma begins to bleed, a hemorrhage can occur, also causing compression of the nerves or spinal cord.

Otherwise they first appear in babies from the ages of 2 weeks to 2 months, growing fairly rapidly for the first month or so, then continuing to grow up until about 5 or 6 months of age. The time period when they are growing is called proliferation. […] About 80 percent of hemangiomas stop growing by about 5 months. After hitting this plateau phase, they stay unchanged for several months, and then begin to slowly disappear over time (called involution). By the time children reach 10 years of age, hemangiomas are usually gone.

  Hemangiomas are the most common type of birthmark or benign tumor of the skin. They are either present at birth or appear shortly after birth and grow rapidly. Most develop on the skin in the head or neck area. […] Infantile hemangiomas follow a specific pattern of growth and involution (shrinking and lightening in color). The emerging stage usually occurs from birth to three months of age, followed by an early and late growth stage, typically from six to 10 months. During the growth phases, the lesions initially expand rapidly and then stabilize. Infantile hemangiomas usually reach the maximum size by five or six months of age. After the first year of life, they slowly shrink and lighten in color, a process called involution. The involution stage may be most rapid between infancy and 4 years of age, but can also progress more gradually over the subsequent five to 10 years of the child’s life.
