Neck lumps in children
- Approach to a complaint
Most neck lumps in children are swollen lymph glands from infections; a few are present from birth and a small number are tumours.
What it is
A neck lump is a frequent reason for consultation in children. Most are reactive lymph nodes after throat or skin infections and resolve. Congenital masses (thyroglossal duct cyst in the midline, branchial cleft anomalies on the side) are the next group, followed by vascular lesions. Malignancy is rare but must be recognised: leukaemia in young children and Hodgkin lymphoma in adolescents. Position, age, duration and associated symptoms guide the approach.
Key questions in the history
- Age, duration and speed of growth.
- Recent sore throat, dental or skin infection, cat scratch, tuberculosis contact?
- Present since birth or a punctum that drains (congenital)?
- Fever, night sweats, weight loss, bruising or pallor (lymphoma, leukaemia)?
- Does it move with swallowing or tongue protrusion (midline thyroglossal cyst)?
Causes and classification
- Inflammatory: reactive lymphadenopathy, bacterial lymphadenitis and abscess, mycobacterial infection.
- Congenital midline: thyroglossal duct cyst, dermoid cyst.
- Congenital lateral: branchial cleft cyst, sinus or fistula.
- Vascular: infantile haemangioma, vascular and lymphatic malformations.
- Neoplastic: lymphoma, leukaemia, other rare tumours (thyroid, sarcoma).
Step-by-step approach
- Take a history and examine all node areas, liver and spleen; measure the lump and note consistency and mobility.
- If there are signs of infection, treat the cause and review in 2 weeks.
- If low risk (small, mobile, recent infection), observe for 3–4 weeks.
- If it persists or grows: blood count and blood film, chest X-ray and tests by context (EBV serology, tuberculin test or IGRA, HIV).
- Ultrasound is the first imaging test; it is well suited to children and characterises cysts.
- Biopsy, decided by the specialist, if the node persists without explanation or any red flag appears.
Neck lumps in children by position
| Position | Most likely | Clue |
|---|---|---|
| Midline, near hyoid | Thyroglossal duct cyst | Painless, mobile; may become infected |
| Lateral, anterior to sternocleidomastoid | Branchial cleft cyst or sinus | Punctum with discharge, recurrent abscess |
| Along the jugular chain or under the jaw | Reactive node or lymphadenitis | Recent infection, tender |
| Supraclavicular | Lymphoma or other malignancy until proven otherwise | Hard, painless, systemic symptoms |
| Skin or soft tissue, from early infancy | Haemangioma or vascular malformation | Colour change, rapid early growth |
Red flags
- Supraclavicular node at any size.
- Hard, fixed or matted nodes, or a node over 2 cm that keeps growing without infection.
- Fever without cause, night sweats, weight loss, pallor, bruising or enlarged liver or spleen.
- Stridor, difficulty swallowing or breathing (compression).
Next step / Initial management
- First workup: careful exam, blood count with smear, and neck ultrasound when the lump persists or is congenital.
- First-line management: treat clear infections (for example antibiotics for bacterial lymphadenitis) and review; an infected thyroglossal cyst is treated with antibiotics before surgery.
- Refer urgently (within days) to paediatric oncology or surgery a child with red flags, especially a supraclavicular node or systemic symptoms.
- Refer the same day to the emergency service a child with airway compression or an abscess with toxic look.
- Refer on a routine basis to paediatric surgery or otolaryngology congenital cysts and sinuses for elective excision.
Test yourself
Think of the answer, then tap the question to see it.
A 6-year-old has a painless midline neck mass at the level of the hyoid. Most likely diagnosis and treatment?
Thyroglossal duct cyst, the most common congenital neck anomaly; ultrasound, then surgical excision by the Sistrunk operation.
A 10-year-old has a recurrently discharging punctum at the anterior border of the sternocleidomastoid. What is it?
A branchial cleft sinus, most often from the second branchial cleft.
A 15-year-old has a hard, painless supraclavicular node, night sweats and weight loss. Next step?
Urgent referral for biopsy: a supraclavicular node with systemic symptoms in an adolescent suggests lymphoma (Hodgkin).
