Cervical Lymphadenopathy in Children

This guideline applies to children up to their 16^th birthday.

It applies solely to patients with suspected cervical lymphadenopathy. In patients with a strongly suspected or confirmed diagnosis of a congenital neck abnormality, please follow the Congenital neck lumps in Children guideline.

Introduction

Neck lumps are common in children and have a broad differential diagnosis, typically categorised into congenital, reactive (infective or inflammatory) and neoplastic.

Although the majority are due to benign self-limiting disease, they usually generate a lot of parental anxiety. Palpable cervical (and sometimes inguinal) lymph nodes are common in young children and often persist for a long time.

Overview of local referral pathways for cervical lymphadenopathy in children

If penicillin allergy, avoid flucloxacillin and use an alternative antibiotic.

Red Flag Features

Patient Age < 6 months
Rapid progressive growth
Associated B symptoms
- fever, night sweats, weight loss etc
Hepatosplenomegaly
Firm/rubbery consistency.
Skin tethering or ulceration
Supraclavicular fossa
=/>3cm
Petechiae/ unexplained bruising or pallor
Known family TB contact

Investigations

If red flag features, consider blood tests and initiate early discussion with the Paediatric Consultant on-call:

FBC with film
LDH
C-Reactive Protein (CRP)
EBV CMV Toxoplasmosis serology

If there are red flag features or suspected abscess formation see referral process below.

Management

In a well child with no red flag features, base initial management on whether there are signs of infection.

Infection suspected:

Prescribe Flucloxacillin for 7-10 days (use alternative antibiotic if penicillin allergic).
Review at 48-72hr – if no improvement, or concerned about abscess formation, contact same-day paediatric first on-call.
Review at the end of the antibiotic course – if lump has resolved, reassure and provide patient information. If it is persistent, arrange neck ultrasound.

No signs of infection:

Lump <2 cm : Reassure and provide patient information. Consider re-review of nodes between 1.5cm-2cm and discuss if enlarging or any worrying features.
Lump > 2cm: Review at 6 weeks:
- Resolved – reassure and provide patient information. Small, morphologically normal lymph nodes may persist and remain palpable for many months due to a lack of subcutaneous fat, superficial site and relative size of the neck.
- > 2cm in absence of red flag features – arrange neck ultrasound.
- Persistent with red flag features – consider blood tests and initiate early discussion/referral with the Paediatric Consultant on-call.

Palpable, cervical (and inguinal) lymph nodes are very common in young children and often persist for a long time.

Advice and Guidance

If benign congenital mass demonstrated on neck ultrasound, seeking ENT Advice and Guidance is an option. See the Congenital neck lumps in Children guideline for further information.
