A case of chemical assault in Hong Kong (case report).

•A case report highlighting a unique protocol for the acute management of chemical burns in Hong Kong.•Urgent (<48h) shaving of chemical burns removes residual chemical load and prevents progressive continuing acid corrosion.•Shaving tangentially to lacuna-like or punctate bleeding, optimally preserves healthy and viable tissues.•Delay in surgical interventions had been associated with higher incidences of hypertrophic scarring and need for further reconstructive surgery.•Trying to prove benefit in terms of an RCT is however ethically challenging.
