Objective: To report a case of simultaneous erythema nodosum and erythema multiforme after local lidocaine injection. Case Summary: A 33-year-old female experienced coexisting erythema nodosum and erythema multiforme after lidocaine spray was used for upper gastrointestinal endoscopy. The reaction was exacerbated after localized injection of 2% lidocaine for a skin biopsy. An objective causality assessment revealed that an adverse drug reaction was highly probable. Discussion: Lidocaine is the most frequently used local anesthetic agent. The coexistence of erythema nodosum and erythema multiforme has been reported in lepromatous leprosy, Yersinia enterocolítica and Yersinia pseudotuberculosis gastrointestinal infection (both with diarrhea), histoplasmosis, hepatitis C, and milker's nodule, but not with lidocaine. Conclusions: If clinicians observe similar lesions after lidocaine exposure, they should suspect an adverse drug reaction and exercise caution in the administration of amide anesthetics to patients with a documented history of adverse reaction to lidocaine.
