Hemangioma

What is a Hemangioma?

A hemangioma is a benign (non-cancerous) growth of blood vessels in the skin or internal organs. They often appear as red or purple raised lesions and are sometimes called “strawberry marks.”

Hemangiomas are most common in infants, but can occur at any age. Most are harmless and may regress over time.

Causes

Primary Causes

• Abnormal growth of blood vessels during development.
• Genetic and embryological factors → exact cause is not fully understood.
• More common in premature infants or low birth weight babies.

Contributing Factors

• Female infants are more frequently affected.
• Multiple hemangiomas may indicate systemic involvement (rare).

Symptoms / Appearance

• Bright red, raised lesions on the skin (superficial hemangiomas).
• Bluish or deep lesions under the skin (deep hemangiomas).
• Size ranges from a few millimeters to several centimeters.
• Usually painless and do not affect function, unless near vital structures.
• May bleed if injured.
• Some hemangiomas grow rapidly in the first few months and then slowly shrink.

Treatments

Observation / Monitoring

• Many hemangiomas shrink and resolve on their own by age 5–10.
• Regular monitoring is sufficient for small, non-problematic hemangiomas.

Medical Treatments

• Beta-blockers (propranolol or topical timolol) → reduce size and redness.
• Corticosteroids → rarely used for rapid growth or functional problems.
• Laser therapy → for superficial lesions or cosmetic concerns.
• Surgery → for large, complicated, or persistent hemangiomas affecting function.

Supportive Care

• Protect from trauma or injury to prevent bleeding or ulceration.
• Gentle skin care for affected areas.

Prevention

• Hemangiomas are largely not preventable as they result from vascular developmental factors.
• Early medical consultation if lesions grow rapidly, ulcerate, or interfere with function.
• Monitor for signs of complications in multiple or large hemangiomas.

FAQs

Q1. Are hemangiomas cancerous?
No, hemangiomas are benign and rarely pose a serious health risk.

Q2. Do hemangiomas go away on their own?
Many shrink or disappear naturally over several years, especially in children.

Q3. When is treatment needed?
If hemangiomas affect vision, breathing, feeding, or cause ulceration, or for cosmetic reasons in older children or adults.

Q4. Can hemangiomas bleed?
Yes, if injured or ulcerated, though bleeding is usually minor.

Q5. Are adults at risk of hemangiomas?
Most hemangiomas appear in infancy, but adults can develop vascular lesions that resemble hemangiomas, which should be evaluated by a dermatologist.
