Q: Concerns About Persistent Lymph Nodes in a Toddler: What to Know

Hello： In response to your question, the presence of lumps in the neck or behind the ear typically requires evaluation based on the color, size, changes over time, tenderness, consistency (soft or hard), and precise location of the lumps, which can be very helpful for diagnosis.

Please ask your question?

Hello, my child is currently one and a half years old.
He was hospitalized for a month last year due to fever and bronchitis.
Since being discharged, he has been treated with traditional Chinese medicine.
He has had two hard lymph nodes behind his ears since last year; although they have decreased in size to about 0.5-1 cm, they are still present.
Since his discharge, aside from having occasionally long eyelashes and experiencing eye allergies, he has received vaccinations for German measles, mumps, pneumococcal disease, and Japanese encephalitis, but has not exhibited any other symptoms.
Is this normal? The pediatrician did not express any concerns.
Should I take him for further examinations or pay attention to anything specific? I would greatly appreciate your response.
A worried mother.

Incomplete information may lead to diagnostic errors.
Based on the information provided, the most likely possibility is lymphadenopathy.
If there are two lumps, one on each side, or both on the same side, and if the lumps on opposite sides are symmetrical and feel as hard as bone, it could indicate bone proliferation.
It is advisable to first consult an otolaryngologist for examination, and if necessary, to undergo chest imaging or blood tests.

More Info

When it comes to persistent lymph nodes in toddlers, it is understandable for parents to feel concerned, especially after a history of illness. In your case, your child has had two hard lymph nodes behind the ears that have persisted for some time, although they have decreased in size to about 0.5-1 cm. Here’s what you should know:

Understanding Lymph Nodes in Children
Lymph nodes are small, bean-shaped structures that are part of the lymphatic system, which plays a crucial role in the immune response. In children, it is common to find lymph nodes that are palpable (able to be felt) due to their active immune systems. Lymph nodes can become enlarged in response to infections, inflammation, or other immune responses.

Common Causes of Persistent Lymphadenopathy
1. Infections: Viral infections, such as those causing colds or flu, can lead to temporary lymph node enlargement. In your child's case, the history of bronchitis and fever could have triggered the enlargement of the lymph nodes.
2. Reactive Lymphadenopathy: This is a benign condition where lymph nodes remain enlarged after an infection has resolved. It is common in children and often does not indicate a serious underlying condition.

3. Vaccination Response: Some vaccines can cause lymph nodes to swell as part of the immune response. Since your child has received several vaccinations recently, this could also be a contributing factor.

4. Other Causes: While less common, persistent lymphadenopathy can be associated with other conditions, including autoimmune diseases or malignancies. However, these are rare in children, especially when there are no other concerning symptoms.

When to Seek Further Evaluation
Given that your child has seen a pediatrician and they did not express concern, it is likely that the lymph nodes are benign. However, you should consider further evaluation if:
- The lymph nodes continue to grow or do not decrease in size over time.

- New symptoms develop, such as fever, night sweats, unexplained weight loss, or persistent fatigue.

- The lymph nodes become hard, fixed, or tender to the touch.

Recommendations
1. Monitoring: Keep an eye on the lymph nodes and note any changes in size or consistency. If they remain stable or decrease further, this is a good sign.

2. Follow-Up: If you have ongoing concerns, it may be worthwhile to schedule a follow-up appointment with your pediatrician. They may recommend further tests, such as blood tests or imaging, if they feel it is necessary.

3. General Health: Ensure your child maintains a healthy diet, adequate hydration, and regular check-ups to monitor their overall health and development.

4. Communication: Keep an open line of communication with your pediatrician. If you notice any new symptoms or changes, do not hesitate to reach out for advice.

In conclusion, while persistent lymph nodes can be concerning, they are often benign in children, especially when there are no accompanying symptoms. Regular monitoring and communication with your healthcare provider are key to ensuring your child's health and addressing any concerns that may arise.
