Conclusion

Delayed hypersensitivity to lidocaine may present as “suture allergy,” as in Case 1. Lidocaine allergy also should be considered in the differential diagnosis of a localized delayed-type hypersensitivity reaction that develops and recurs at sites of surgical procedures.[8] Other clinical presentations are treatment failure, typical contact allergy, and other local skin or dental reactions.

We concur with Mackley and colleagues[6] that if a patient displays patch-test sensitivity to a local anesthetic, further patch and intradermal testing is recommended although the results may be discordant.[13]
