Lymphadenopathy refers to the enlargement of lymph nodes, and it is commonly observed in the neck region of children. This condition is usually caused by infections, inflammatory reactions, or, in rare cases, malignancy (cancer). Approximately 90% of pediatric lymphadenopathies are associated with infections and resolve spontaneously after the infection subsides. These cases rarely require intervention.

Symptoms

The most common finding is a swelling on one or both sides of the neck, which may or may not be painful. Other accompanying symptoms may include:

• Fever

• Fatigue

• Pain while swallowing

• Sore throat

Clinical Evaluation

During physical examination, certain features of the lymph nodes help determine the underlying cause:

• Tender vs. non-tender

• Soft vs. firm consistency

• Mobile vs. fixed to surrounding tissues

• Well-defined vs. irregular borders

Tender, soft, mobile, and well-circumscribed lymph nodes are generally benign. After a detailed history and physical exam, if the lymphadenopathy persists for an extended period or is suspected to be malignant, ultrasound imaging is recommended.

If ultrasonography does not clearly confirm a benign diagnosis, surgical excision and pathological examination of the lymph node are necessary to rule out malignancy.

Although the vast majority of pediatric lymphadenopathies are benign, some malignant conditions may present only with lymph node enlargement. Therefore, if you notice a swelling in your child’s neck, it is essential to consult a pediatrician or pediatric surgeon without delay.

Lymphadenopathies usually respond well to treatment. However, accurate diagnosis of the underlying cause and appropriate treatment are critical. Early detection and management can significantly reduce the risk of complications and help maintain the child’s overall health.
