Mnemonic

Lymph Node Examination

A memory aid for examining lymph nodes and interpreting lymphadenopathy.

Expansion

Site, size, consistency, tenderness, fixation and the drainage area

Expansion

Cervical chain, examined from behind

  1. Submental
  2. Submandibular
  3. Pre-auricular
  4. Post-auricular
  5. Occipital
  6. Superficial cervical, along the sternocleidomastoid
  7. Deep cervical
  8. Posterior triangle
  9. Supraclavicular

Then axillary, epitrochlear, inguinal and popliteal, plus liver and spleen.

What to describe

  • Site and whether localised or generalised
  • Size, in centimetres; over 1 cm is usually significant, over 2 cm more so
  • Consistency: soft, rubbery, hard, fluctuant
  • Tenderness
  • Mobility: mobile, matted or fixed to skin or deep structures
  • Overlying skin change or sinus

Interpretation

Character Suggests
Tender, soft, mobile Infection
Rubbery, mobile, painless Lymphoma
Hard, fixed, painless Carcinoma
Matted, may discharge Tuberculosis

Virchow’s node, a left supraclavicular node, drains the thoracic duct and signals intra-abdominal malignancy, classically gastric. When palpable with a positive Troisier sign it is a genuinely useful physical finding.

Localised lymphadenopathy demands examination of the whole drainage area including the skin, scalp, mouth, ears and the limb distal to it.
