Hemangiomas are benign (non-cancerous) growths formed by an abnormal buildup of blood vessels in the skin or internal organs. Often referred to as "strawberry marks" due to their red appearance, these vascular tumors are most commonly seen in infants. Though typically harmless and self-resolving, hemangiomas can sometimes cause complications that require medical attention.
Hemangiomas can be classified into several types based on their location and structure:
Superficial (Capillary) Hemangiomas: These are found on the skin’s surface, appearing bright red and raised. They are most common in infants and often resemble strawberries.
Deep (Cavernous) Hemangiomas: These lie beneath the skin and appear bluish due to the depth of the blood vessels. They can grow larger and may affect underlying tissues.
Mixed Hemangiomas: These involve both superficial and deep components, combining features of both types.
Internal Hemangiomas: These form inside the body, such as in the liver, brain, or intestines, and are usually detected through imaging scans.
Most hemangiomas are discovered shortly after birth. They typically go through three stages:
Proliferative Phase: Rapid growth occurs during the first few months of life.
Plateau Phase: Growth slows down and stabilizes.
Involution Phase: The hemangioma gradually shrinks and fades over several years.
Common signs and symptoms include:
Bright red or bluish lump on the skin.
Swelling or raised surface.
Rapid increase in size during infancy.
Ulceration or bleeding (in some cases).
Vision or breathing issues if located near eyes, nose, or throat.
The exact cause of hemangiomas is unknown. However, several factors are thought to contribute:
Genetic Factors: A family history of vascular anomalies can increase the risk.
Premature Birth: Hemangiomas are more common in babies born before full term.
Female Gender: Girls are more likely to develop hemangiomas than boys.
Low Birth Weight: Infants with lower birth weights are at higher risk.
These tumors are not caused by maternal actions during pregnancy and are not contagious.
There is no definitive way to prevent hemangiomas, as their development is mostly due to uncontrollable biological factors. However, early detection and monitoring can prevent complications. Parents should:
Observe any skin changes in newborns.
Report rapidly growing marks to a pediatrician.
Avoid skin irritation or trauma around the hemangioma site.
While most hemangiomas are harmless, certain precautions can minimize risks:
Protect the Area: Use soft clothing to avoid friction and reduce the risk of bleeding or ulceration.
Keep Clean: Maintain hygiene to prevent infection, especially in ulcerated hemangiomas.
Avoid Self-Treatment: Refrain from applying over-the-counter creams without medical advice.
Most hemangiomas resolve on their own without intervention. However, treatment may be necessary if they cause pain, interfere with vital functions, or leave scars.
Common treatments include:
Beta-Blockers (e.g., Propranolol): The most effective treatment, helping shrink the tumor.
Topical Treatments: Timolol gel may be applied for small superficial hemangiomas.
Laser Therapy: Used for residual redness or to treat ulcerated hemangiomas.
Surgery: Rarely needed, reserved for very large or problematic lesions.
Corticosteroids: Sometimes used if beta-blockers are not effective or suitable.
Immediate medical attention is advised if:
The hemangioma grows rapidly.
It ulcerates, bleeds, or becomes infected.
It obstructs vision, breathing, feeding, or hearing.
It causes significant cosmetic concern or emotional distress.
Pediatricians or dermatologists typically handle such cases, and early evaluation can prevent long-term issues.
In conclusion, hemangiomas are usually a harmless childhood condition, but careful observation and appropriate care are essential. With medical advances, even problematic hemangiomas can be effectively managed, ensuring a healthy and scar-free future for affected children.
