Dermatologists may see patients with actual or suspected local anaesthetic (LA) allergy who require an urgent dermatological procedure to be performed without time for formal allergy testing. We report a case of shave biopsy and subsequent excision biopsy of an atypical naevus performed using tumescent analgesia with 0.9% saline containing benzyl alcohol preservative. The tumescence itself and the benzyl alcohol present in the 0.9% saline solution provided sufficient analgesia for excision. This technique may be an option for managing urgent procedures in patients suspected or known to have allergy to LA.
