An unusual complication of minor surgery: contact dermatitis caused by injected lidocaine

True allergy to lidocaine is rarely encountered in the clinical setting. With the increasing number of over-the-counter drugs containing topical amides, the incidence of lidocaine-induced contact dermatitis seems to be increasing (1, 2). Herein, we describe the interesting case of a woman with a previous poorly defined severe local reaction to an injectable filler mixed with lidocaine who presented with bullous contact dermatitis induced by subcutaneous injection of lidocaine during minor surgery.
