What should be done about a hemangioma in the subcutaneous tissue at the back of a toddler's head?

Hemangiomas under the scalp at the back of the head in infants can be managed through close observation, topical medications, laser therapy, local injections, or minimally invasive interventional procedures. Due to the sensitive location, care must be taken to avoid damaging the scalp or skull; therefore, gentle and less invasive treatments are preferred. If the hemangioma grows rapidly, ulcerates with bleeding, or compresses surrounding tissues, prompt medical attention is recommended.

1. Close observation: For small, asymptomatic subcutaneous hemangiomas, regular monitoring and recording of size and texture changes are sufficient. Most such hemangiomas spontaneously regress between ages 1 and 5. Avoiding early intervention helps prevent irritation to the infant’s delicate scalp and reduces unnecessary medical procedures.

2. Topical medications: For superficial, slow-growing subcutaneous hemangiomas, apply pediatric-specific medicated creams as directed by a physician. The medication penetrates through the scalp to inhibit abnormal blood vessel proliferation. This method is simple, has minimal side effects, and does not interfere with the infant’s daily activities.

3. Laser therapy: For subcutaneous hemangiomas that are bright red and growing quickly, low-energy lasers can be used to destroy abnormal blood vessels and promote lesion shrinkage. Treatment should avoid areas where the skull is thin. Post-procedure scalp care is essential to prevent infection.

4. Local injection: For medium-sized hemangiomas that have not invaded the skull, low-concentration medication can be precisely injected into the lesion to reduce its size. Dosage must be strictly controlled during injection to minimize risks of damage to scalp nerves and subcutaneous tissues.

5. Minimally invasive intervention: For large hemangiomas affecting head appearance or compressing subcutaneous structures, a minimally invasive catheter is used to deliver embolic agents into the abnormal vessels, cutting off blood supply and inducing regression. This approach involves minimal trauma and allows for quicker recovery.

In daily care, choose soft, breathable pillows for infants to avoid friction on the hemangioma at the back of the head. When cleaning the scalp, gently wipe with lukewarm water, keep the area dry, and minimize physical contact to prevent discomfort.
