Swollen Glands (Cervical Lymphadenitis)

Overview

Cervical lymphadenitis refers to inflammation and enlargement of the lymph nodes located in the neck (cervical region). Lymph nodes are small, bean‑shaped structures that filter lymph fluid and trap bacteria, viruses, and other foreign particles. When they become infected or irritated, they swell and may become tender.

While any age group can develop cervical lymphadenitis, it is most common in:

• Children aged 2–10 years (about 70 % of cases are pediatric) <sup>[1]</sup>
• Young adults with compromised immune systems

Worldwide, swollen neck glands account for roughly 5–10 % of all pediatric primary‑care visits in the United States and Europe <sup>[2]</sup>. In low‑resource settings, the condition can be more severe due to delayed treatment of underlying infections.

Symptoms

The clinical picture varies from mild, self‑limiting swelling to painful, fluctuant masses that suggest abscess formation. Common symptoms include:

• Enlarged lymph nodes – usually 0.5–2 cm, may feel rubbery or hard.
• Pain or tenderness – especially when touched or with neck movement.
• Redness or warmth over the node (sign of inflammation).
• Fever – low‑grade (≤38 °C) in viral causes; higher fevers (>38.5 °C) suggest bacterial infection.
• Headache, malaise, and fatigue – non‑specific systemic symptoms.
• Difficulty swallowing or sore throat – when nodes are near the tonsillar area.
• Skin changes – in severe cases the overlying skin may become ulcerated.
• Fluctuance – a soft, fluid‑filled “wave” on palpation indicating an abscess.
• Unexplained weight loss or night sweats – warrant evaluation for malignancy or chronic infection.

Causes and Risk Factors

Infectious Causes

• Staphylococcus aureus and Streptococcus pyogenes – most common bacterial culprits.
• Upper‑respiratory viruses (e.g., adenovirus, EBV, CMV, rhinovirus).
• Cat‑scratch disease (Bartonella henselae).
• Tuberculosis (Mycobacterium tuberculosis) – especially in endemic areas.
• Fungal infections (Histoplasma, Coccidioides) in immunocompromised hosts.

Non‑infectious Causes

• Autoimmune diseases – e.g., systemic lupus erythematosus, Kawasaki disease.
• Malignancies – lymphoma, metastatic squamous cell carcinoma.
• Drug reactions – certain immunizations or medications may trigger reactive lymphadenitis.

Risk Factors

• Recent upper‑respiratory infection or dental/oral trauma.
• Immunosuppression (HIV, chemotherapy, organ transplant, chronic steroids).
• Close contact with cats (cat‑scratch disease) or pets with skin infections.
• Living in or travel to regions with high TB or endemic fungal disease prevalence.
• Poor oral hygiene or recent dental procedures.

Diagnosis

Diagnosis combines a thorough history, physical examination, and targeted investigations.

Clinical Assessment

1. History – onset, duration, associated fever, recent infections, travel, cat exposure, immunization status.
2. Physical exam – size, consistency, mobility, tenderness, overlying skin changes, presence of fluctuation.

Laboratory Tests

• Complete blood count (CBC) – leukocytosis suggests bacterial infection; lymphocytosis may point to viral etiology.
• Inflammatory markers (CRP, ESR) – elevated in most infectious causes.
• Throat or wound cultures – when a specific source is suspected.
• Serology for EBV, CMV, Bartonella, HIV, or TB (Quantiferon‑TB Gold).

Imaging

• Ultrasound – first‑line; differentiates solid from cystic nodes, identifies abscesses.
• Contrast‑enhanced CT or MRI – used when deep neck space infection, airway compromise, or malignancy is suspected.

Procedural Diagnosis

• Fine‑needle aspiration (FNA) – obtains cellular material for cytology, culture, and Ziehl‑Neelsen staining (TB).
• Excisional biopsy – indicated when lymphoma or persistent unexplained enlargement is a concern.

Treatment Options

Treatment is tailored to the underlying cause, severity, and patient factors.

1. Empiric Antibiotics (Bacterial Lymphadenitis)

• First‑line: Clindamycin 300 mg PO q6h or Amoxicillin‑clavulanate 875/125 mg PO q12h for 7–10 days.
• Consider MRSA‑active agents (e.g., trimethoprim‑sulfamethoxazole, doxycycline) if community‑associated MRSA is prevalent.
• Intravenous therapy (e.g., cefazolin, vancomycin) if the patient is ill‑appearing, has an abscess, or cannot take oral meds.

2. Antiviral or Antifungal Therapy

• EBV – usually supportive; antivirals rarely indicated.
• TB – standard 6‑month regimen (isoniazid, rifampin, pyrazinamide, ethambutol) per CDC guidelines <sup>[3]</sup>.
• Fungal – itraconazole or fluconazole based on species and susceptibility.

3. Drainage of Abscesses

If an abscess forms (fluctuant, >2 cm, or causing airway compromise), it should be aspirated or surgically incised and drained under sterile conditions. Post‑procedure antibiotics are continued for 7–10 days.

4. Supportive Care

• Analgesics – acetaminophen or ibuprofen for pain and fever.
• Warm compresses – 15 min, 3–4 times daily, may speed resolution of small, non‑purulent nodes.
• Hydration and rest.

5. Management of Underlying Conditions

Autoimmune or malignant causes require disease‑specific therapy (e.g., immunosuppressants, chemotherapy, radiation). Referral to a specialist (infectious disease, hematology/oncology, otolaryngology) is essential.

Living with Swollen Glands (Cervical Lymphadenitis)

Most patients recover fully with appropriate treatment, but some may experience lingering discomfort or anxiety about recurrence. Practical tips for daily life include:

• Monitor size and pain – keep a simple diary; note any increase >5 mm or new tenderness.
• Maintain oral hygiene – brush twice daily, floss, and schedule regular dental check‑ups.
• Stay up‑to‑date on vaccinations – especially influenza, COVID‑19, and tetanus.
• Warm salt‑water gargles (½ tsp salt in 8 oz warm water) 3–4 times daily can soothe sore throats that often accompany cervical lymphadenitis.
• Avoid tight collars or necklaces that may compress swollen nodes.
• Exercise gently – low‑impact activities (walking, stretching) promote circulation without stressing the neck.
• Stress management – chronic stress can blunt immune response; consider mindfulness or yoga.

Prevention

Because many cases are triggered by infections, prevention focuses on reducing exposure to pathogens and supporting immune health.

• Practice good hand hygiene (wash ≥20 seconds, especially after coughing or handling pets).
• Cover coughs and sneezes with a tissue or elbow.
• Avoid sharing utensils, toothbrushes, or lip products.
• Promptly treat dental caries, gum disease, and oral infections.
• For cat owners: wash hands after handling cats; keep cats’ claws trimmed to lower cat‑scratch risk.
• Ensure children receive routine immunizations (MMR, DTaP, Varicella, etc.).
• Maintain a balanced diet rich in vitamins A, C, D, zinc, and omega‑3 fatty acids to support immune function.
• Quit smoking and limit alcohol, both of which impair mucosal immunity.

Complications

When left untreated or poorly managed, cervical lymphadenitis can lead to serious sequelae:

• Deep neck space infection – spread to retropharyngeal, parapharyngeal, or mediastinal spaces; can cause airway obstruction.
• Abscess formation – may require surgical drainage and can erode surrounding structures.
• Septicemia – systemic infection, more common in immunocompromised patients.
• Chronic lymphadenopathy – persistent enlarged nodes that may need biopsy to rule out malignancy.
• Scarring or fibrosis – can cause restricted neck movement.
