Lymphangioma - Causes, Symptoms, and Treatment

What Is Lymphangioma?

Lymphangioma is a benign, uncommon lump that develops in the lymphatic system.

The lymphatic system is similar to a drainage system in the body. It circulates a clear fluid known as lymph, which helps combat germs and prevents excess fluid from building up in the tissues. In lymphangioma, these vessels (small tubes) do not develop properly. Instead of flowing smoothly, the fluid accumulates in small sacs, which appear as soft masses under the skin.

Lymphangioma is often present at birth, so it is considered a congenital issue. Although it is not cancer, the bumps can become large and compress the surrounding areas of the body. Occasionally, this leads to problems with breathing, eating, or appearance. Lymphangioma occurs in 1 in 4,000 births. Most children are diagnosed with lymphangioma (known as pediatric lymphangioma) at birth or in infancy. Small, unnoticed ones, in some cases, may persist into adulthood.

What Are the Symptoms of Lymphangioma?

Parents usually notice lymphangioma symptoms as lumps on their child's face, neck, or armpit within the first two years of life. The symptoms vary based on the location of the lump and how large it gets. Some are extremely small and harmless, but others may be serious.

Some of the common symptoms are:

• Soft swelling or lumps under the skin.

• Skin appears bluish or transparent above the lump.

• Swelling could occur rapidly, particularly after an infection.

• Difficulty breathing or swallowing if the lump is on the neck or close to the airway.

• Pain or pressure from larger lumps.

• Redness, tenderness, or fever if the lump becomes infected.

What Are the Three Types of Lymphangioma?

Lymphangiomas are classified into three categories:

Capillary lymphangioma:

• Appear flat or slightly elevated on the skin, almost like a birthmark.

• Small, painless, and not serious.

Cavernous lymphangioma:

• Composed of larger lymph vessels.

• Feel soft and spongy on the skin.

• Tend to spread into surrounding tissues, which makes surgery more difficult.

• May suddenly enlarge after an infection.

Cystic lymphangioma:

• The most common and serious form.

• Composed of large fluid-filled pouches.

• Typically appear in the armpit, groin, or neck.

• If extremely large, they may block the airway and cause breathing or swallowing difficulties in infants.

• Usually requires early intervention.

What Causes Lymphangioma?

There is no absolute cause or reason known for lymphangioma. Some of the possible causes are listed below:

• Birth defect (congenital) - Most occur before birth because the lymph vessels fail to connect properly.

• Genetic association - Occasionally seen in infants with genetic conditions such as Turner syndrome or Down syndrome (a genetic disorder).

• Rare later-onset cases - Very rarely, lymphangiomas can occur after trauma, infection, or surgery that damages lymph vessels.

• Growth triggers - When bleeding or infection occurs within the cyst, the swelling may suddenly increase.

Why Does Lymphangioma Occur?

It should be noted that lymphangioma does not usually occur due to family history and is not inherited. In most children, it occurs by chance during development in the womb. Doctors believe this happens when small parts of the lymph system become cut off and do not join the main channels. Since fluid has no way to escape, it collects and forms cysts or lumps. Although research is ongoing, it is widely considered a developmental issue, not caused by anything parents did or did not do during pregnancy.

How Is Lymphangioma Treated?

Lymphangioma treatment varies with the size, type, and location of the lump. 90 percent of lymhangioma are diagnosed before the age of two. Some require no treatment at all, while others need medical attention.

1. Observation - If the lump is small and harmless, doctors may simply monitor it with routine visits to check for growth or complications.

2. Surgery - Doctors may remove the lump surgically. Surgery works best when the lump is in a fixed location, though it may be difficult if it spreads into vital tissues. Risks include scarring, recurrence, or nerve damage.

3. Laser therapy - Used for small surface lumps, particularly effective for capillary-type lymphangioma.

4. Medications - Antibiotics are prescribed if an infection occurs. Painkillers may be given if the child experiences pain from lymphangioma.

5. Sclerotherapy - Sclerotherapy is one of the most effective and patient-suitable treatments for lymphangioma because surgery can be challenging when the malformation involves vital structures such as nerves, vessels, or the airway. It is a minimal procedure done under ultrasound or fluoroscopy guidance to properly place the sclerosant into the cysts. It is employed to treat enlarged or abnormal blood vessels and lymphatic malformations.

The treatment entails injecting a chemical solution known as a sclerosant into the cyst or affected vessel itself. The solution irritates the lining of the vessel or cyst, causing it to collapse, adhere to itself, and finally be absorbed by the body. Through repeated treatments, the treated cyst or vessel becomes smaller, and the symptoms resolve. Multiple sessions may be necessary for definitive resolution, depending on the size and number of cysts.

How Can I Prevent Lymphangioma?

Unfortunately, lymphangioma cannot be prevented, as it develops during fetal growth.

However, sometimes doctors can detect it early:

• Pregnancy ultrasound - May reveal large cystic hygromas (fluid-filled sacs) before birth.

• Genetic counseling - Recommended in families with certain genetic conditions.

• Early medical visits - If parents notice swelling or lumps, early consultation helps in timely treatment.

• Lifestyle- Lifestyle or dietary changes cannot prevent it. The best approach is early detection and management. There is a 10 to 27 percent recurrence rate.

Conclusion

Lymphangioma is an uncommon growth of the lymphatic system. It is not cancer, but it can cause problems depending on its size and location. Most cases occur in children, with symptoms like soft lumps, swelling, and sometimes breathing or swallowing difficulties.

Modern treatments such as surgery, sclerotherapy, and laser therapy are effective.

Key Takeaways From iCliniq
