Multifocal, fixed-drug eruption masquerading as recurrent erythema multiforme.

Fixed drug eruptions often have a characteristic appearance, which, when correlated with the clinical history, can be easily identified. However, multifocal fixed drug eruptions, especially the non-pigmenting variety, can present a diagnostic challenge, especially in the absence of a complete medication history. We present such a case, in which the patient was taking two over-the-counter medications, both of which contain uncommon causes of multifocal fixed drug eruptions.
