Synopsis
Distinguish common reactive childhood nodes from patterns needing very urgent lymphoma assessment, recognise mediastinal and abdominal emergencies, investigate in a staged way without false reassurance from ultrasound, and obtain diagnostic tissue safely before steroid exposure.
- Most childhood nodes are reactive, but unexplained lymphadenopathy or splenomegaly warrants consideration of very urgent specialist assessment within 48 hours under NICE NG12.
- Concerning features are supraclavicular location, progressive enlargement, firmness, fixation, generalisation, persistence without infectious trajectory or associated systemic and compressive symptoms.
- Measure and map nodes precisely; document tenderness, mobility, skin change and liver and spleen findings rather than using the vague label 'glands up'.
- First-line tests in a concerning pattern are FBC with film, CRP or ESR, renal and liver profile, LDH and urate, selected infection tests, and chest radiograph when mediastinal disease is possible.
- Ultrasound is first-line imaging for a superficial nodal mass when anatomy or suppuration is uncertain, but reassuring sonographic appearance cannot reliably exclude lymphoma.
- Reference-standard diagnosis is adequate tissue, usually an excisional node biopsy, for architecture, histology, immunophenotyping and molecular studies.
- Avoid empirical corticosteroids before tissue diagnosis unless the paediatric oncology team directs emergency treatment; they can shrink lymphoma and compromise classification.
- Fine-needle aspiration often provides insufficient architecture for childhood lymphoma and should not replace the specialist-planned biopsy.
- Keep a child with orthopnoea upright and obtain anaesthetic, oncology and intensive-care planning before CT sedation or general anaesthesia.
- A short observation plan for likely reactive nodes must specify the review date, expected regression and earlier triggers for growth, systemic symptoms or respiratory change.
Key red flags
Unexplained lymphadenopathy or splenomegaly in a child or young person warrants consideration of very urgent specialist assessment within 48 hours under NICE NG12.
A supraclavicular, hard, fixed, non-tender, progressively enlarging or generalised node pattern is more concerning than small mobile cervical nodes during infection.
Drenching night sweats, unexplained fever, weight loss, pruritus, breathlessness or persistent bone pain increases concern when nodes are unexplained.
Orthopnoea, cough, stridor, facial swelling or venous distension suggests a mediastinal mass and creates positional and anaesthetic danger.
Abdominal mass, distension, early satiety, bowel symptoms or rapidly worsening pain may reflect bulky abdominal lymphoma or tumour lysis risk.
Pallor, petechiae, hepatosplenomegaly, bone pain or additional cytopenias raises acute leukaemia as an urgent alternative or marrow involvement.
Investigation priorities
Identify leukaemia, cytopenias or marrow involvement in unexplained generalised lymphadenopathy.
Confirm anatomy, size and suppuration and guide the next surgical or imaging step.
Management branches
Small mobile nodes accompany a resolving local infection and no red flag is present.
- Treat the identified infection only when bacterial features justify it and avoid empirical repeated antibiotics.
- Record node size and arrange a specific clinical review to confirm regression.
- Bring review forward for growth, persistence, new systemic symptoms, splenomegaly or breathing change.
