About Infantile Hemangioma (Strawberry Hemangioma)
The causes of infantile hemangioma involve the abnormal growth of endothelial cells and the formation of abnormal blood vessels. This leads to the development of benign vascular tumors in children. The exact underlying mechanisms are not fully understood, but several factors contribute to its development.
Non-modifiable risk factors for infantile hemangioma are factors that cannot be changed. These include:
- Maternal age: Advanced maternal age has been associated with an increased risk.
- First trimester bleeding: Bleeding during the first trimester of pregnancy has been linked to a higher incidence.
- Preeclampsia: Women with preeclampsia, a condition characterized by high blood pressure during pregnancy, have a higher risk.
- Placental abnormalities: Problems with the placenta during pregnancy can increase the likelihood of developing infantile hemangioma.
- Gender: Girls are more commonly affected than boys.
- Prematurity: Premature babies have a higher risk.
Modifiable risk factors are factors that can be influenced or changed. The modifiable risk factors for infantile hemangioma are not well-defined. However, there is some evidence that suggests certain factors may play a role, including:
- Smoking: Maternal smoking during pregnancy has been associated with an increased risk.
- Medications: Some studies have suggested that certain medications may influence the development of infantile hemangioma, but further research is needed to confirm these findings.
It's important to note that while these risk factors may increase the likelihood of developing infantile hemangioma, they do not guarantee its occurrence. If you have concerns about your child's risk or symptoms, it's best to consult with a healthcare professional for an accurate diagnosis and appropriate management.
The most common symptoms of infantile hemangioma include the appearance of a red mark or lesion on the skin, often referred to as a "strawberry mark". The mark usually appears when the infant is 3 to 6 weeks old. It may grow in size for about 5 months before it stops growing. After this initial growth phase, the hemangioma slowly fades away over several years
In later stages, progression, or higher severity of infantile hemangioma, the following symptoms may occur:
- Residual skin changes such as scarring, discoloration, or extra skin in the area of the lesion
- Multiple lesions may appear in different parts of the body
- In some cases, the hemangioma may involve deeper tissue and appear blue or purple in color
- Complications such as infection, bleeding, pain, or scarring may require treatment
It's important to note that while most infantile hemangiomas are harmless and do not require intervention, some cases may require medical attention. If you notice any concerning symptoms or changes in your child's hemangioma, it's best to consult with a healthcare professional for proper evaluation and guidance.
To diagnose infantile hemangioma (strawberry hemangioma), the following examinations, tests, and procedures are commonly performed:
- Physical exam: Your child's doctor can make a diagnosis during a physical exam by visually inspecting and palpating the hemangioma.
- Biopsy: In some cases, if the mark is deep or close to a major organ, a biopsy (tissue removal) may be recommended to ensure it doesn't go deeper into other tissues.
- CT scan or MRI scan: These imaging tests may be used to determine the depth and extent of the hemangioma.
To determine the stage or severity of infantile hemangioma (Strawberry Hemangioma), additional examinations, tests, and procedures may include:
- Thermography: Thermographic imaging is an alternative tool for clinically monitoring hemangioma extensions. It measures temperature variations induced by the hemangioma accurately.
- Doppler ultrasonography or magnetic resonance imaging: These techniques can estimate depth or confirm difficult assessments of the hemangioma.
It's important to consult with your child's healthcare professional for a proper diagnosis and to discuss which examinations, tests, and procedures are necessary for their specific situation.
The goals of treatment for infantile hemangioma (strawberry hemangioma) are to:
- Inhibit growth and promote regression: Medications like propranolol, a nonselective beta blocker, can be used to inhibit the growth of hemangiomas and promote regression. Propranolol works by reducing blood flow to the tumor and inducing apoptosis (cell death) in the abnormal blood vessels.
- Prevent complications: Early intervention is important to prevent complications such as ulcers, bleeding, infection, and scarring. Topical medications like lauromacrogol and triamcinolone acetonide can be used to treat hemangiomas on the surface of the skin.
- Minimize long-term consequences: Without treatment, approximately half of patients with infantile hemangioma may experience telangiectasia (dilated blood vessels), fibrolipoma (fatty tissue growth), and skin atrophy. Systemic treatments like propranolol can help minimize these long-term effects.
- Individualized approach: The choice of treatment depends on factors such as the size, location, and severity of the hemangioma. Treatment options may include oral medications (propranolol), topical medications (lauromacrogol, triamcinolone acetonide), topical injection, laser therapy, or surgical resection.
It is important to consult with a healthcare professional to determine the most appropriate treatment plan for each individual case. They will consider the specific characteristics of the hemangioma and any potential risks or side effects associated with different treatment options.
