Understanding Hemangiomas: What Parents Should Know

Hemangiomas are common, usually harmless growths made up of extra blood vessels. Though it's possible to develop a hemangioma at any age, they most commonly appear in newborns or infants. Understandably, seeing a new mark on your baby’s skin can feel surprising or even a little worrying. With the right information and support, you can feel confident caring for your child and knowing when to seek guidance.

What Is a Hemangioma?

Hemangiomas occur when clusters of blood vessels grow and bunch together. Approximately 10% of all infants are born with one or develop one within their first year of life.

What Does a Hemangioma Look Like?

Hemangiomas often show up as:

• Bright red, deep purple or brown marks on the skin
• Flat spots that later become more noticeable
• Slightly raised, soft patches

Some hemangiomas grow on the skin's surface and are bright red, often called cherry hemangiomas, while others develop deeper and can look almost bluish. While each one is unique, your child's pediatrician or a dermatologist can easily identify most with a simple exam.

Hemangiomas can form anywhere on your baby's body, including the arms, legs or torso. In many cases, they're not a cause for concern and may grow for a short time after birth and shrink gradually on their own, often leaving minimal or no lasting changes.

It’s completely natural to feel concerned, especially if a hemangioma is more visible, like on the face. The good news is that many fade over time, and with the right care and guidance, you can feel confident knowing your child will be supported every step of the way. Even if it seems minor, having your pediatrician take a look can offer reassurance and help you understand what to expect.

Types of Hemangiomas

While the exact cause isn’t fully understood, it's thought that hemangiomas develop from extra blood vessel growth during pregnancy, and include three primary types:

Infantile Hemangioma

An infantile hemangioma is the most common type. This type usually appears within the first few weeks of life, often grows rapidly during the first months and slowly shrinks over several years. Most infantile hemangiomas require little to no treatment and resolve on their own.

Congenital Hemangioma

A congenital hemangioma is present at birth. Some shrink quickly within the first year, while others may stay the same size. Because they behave differently, your child’s pediatrician may recommend monitoring or treatment if it does not shrink or causes functional issues, such as difficulty breathing or eating.

Internal Hemangioma

Hemangiomas may also develop internally, most commonly as spots on the liver called hepatic hemangiomas. They can also grow in the brain, intestines or bones.

It's important to remember that, while they're technically considered tumors, hemangiomas are benign (noncancerous) and can be left untreated in most cases.

Hemangioma Removal Options

If treatment is needed, whether for functional or aesthetic reasons, hemangioma removal options may include:

• Laser therapy to improve appearance
• Medications to slow or shrink growth
• Minor in-office procedures in select cases

Your child’s healthcare provider will suggest the best options available based on the size, location and symptoms your child experiences. While there isn’t a way to prevent hemangiomas, many resolve naturally or respond well to treatment when needed. The goal is always to protect your child’s health while minimizing long-term effects.

When to See a Doctor

While most hemangiomas are harmless, it’s important to seek care if you notice:

• A hemangioma near the eye, nose or mouth
• Bleeding, ulceration or signs of infection
• Concerns about function or development
• Rapid growth or changes in appearance

A quick evaluation can bring peace of mind and ensure your child gets the right care if needed.
