title: Fixed drug eruption induced by lidocaine and patch testing.
abstract: Fixed drug eruption (FDE) is a peculiar drug-induced cutaneous reaction, that characteristically reappears at the same site when the etiologic drug is readministered. We present a case of a 27-year old male who was referred to us after two episodes of erythema on the palms, soles, and genital areas with posterior desquamation after receiving local anesthetics. Skin tests with lidocaine, mepivacaine and bupivacaine were negative. Eight hours after challenge with lidocaine the lesions reoccurred. Patch tests with lidocaine on healthy skin and residual lesions were negative, but 48 hours later the lesions reappeared on the same areas as before. Challenge with mepivacaine and bupivacaine were negative.
