SU18.3 | Surgical Swelling Examination — Summary & Reflection

KEY TAKEAWAYS

The clinical examination of a surgical swelling is a reproducible skill performed in a fixed order so that nothing is missed. Begin by determining the anatomical plane and tissue of origin, then inspect (site, size, shape, surface, overlying skin, number, visible movement) and palpate (temperature, tenderness, edge, consistency) before eliciting the special signs: fluctuation (fluid, tested in two planes), transillumination (clear fluid), expansile pulsation (aneurysm — never incise), reducibility with a cough impulse (hernia), and plane and fixity. Percuss and auscultate where relevant, and always examine the regional lymph nodes. Interpret the signs together through the congenital/traumatic/inflammatory/neoplastic sieve to form a ranked differential — fluctuant + tender = abscess; soft, mobile, slip-sign = lipoma; transilluminant = clear-fluid cyst; hard, fixed + matted nodes = malignancy; reducible groin lump with cough impulse = hernia. Investigations (ultrasound first, then FNAC or excision biopsy, with CT/MRI for deep/malignant lesions) follow the examination, and the treatment plan flows from the working diagnosis.

REFLECT

Recall the last lump you examined — in a clinic, on a ward, or in a simulated long case — or imagine the neck swelling from the hook in front of you now. Did you follow a fixed sequence, or did you reach out and prod at random? Could you, next time, move cleanly through inspection and palpation, deliberately test for fluctuation in two planes and for transillumination, check for an expansile pulsation before even thinking of a needle, and remember to examine the draining nodes? Reflect on one discipline you will build — measuring rather than estimating size, or never finishing a swelling examination without the regional nodes — so that the structured routine becomes automatic and your description, differential and plan are clear enough for any colleague to follow.
