Key Points

To report the clinical course and conservative management of pronounced localized soft-tissue swelling following an accidental human needlestick injury with a light liquid paraffin-adjuvanted swine vaccine.
Clinical assessment and serial monitoring of a female livestock worker in her 30s presenting to an emergency department 5 hours after accidental puncture to the dorsum of the left hand.
Outpatient surveillance protocol evaluating progressive local inflammatory reaction and screening for compartment syndrome over a 3-day period.
Initial presentation at 5 hours post-injury showed only mild local edema without sensory or vascular signs of compartment syndrome.
Marked inflammatory swelling developed by 27 hours post-injury due to the light liquid paraffin adjuvant, which improved by day 3 without requiring decompressive fasciotomy or surgical debridement.
