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.
固定性药疹通常具有特征性表现，结合临床病史，很容易识别。然而，多灶性固定性药疹，尤其是无色素沉着型，可能带来诊断挑战，特别是在缺乏完整用药史的情况下。我们报告这样一例病例，该患者正在服用两种非处方药，这两种药物均含有导致多灶性固定性药疹的罕见病因。
