Drug eruptions: Great imitators
1Department of Dermatology, National Taiwan University Hospital and National Taiwan University College of Medicine, Taipei, Taiwan.
Abstract:
Drug eruptions are among the great masqueraders that sometimes cause diagnostic challenges in clinical practice. Pharmacologic agents may induce skin changes, sharing the same pathophysiologic mechanisms of specific dermatoses, or inducing drug eruptions with different pathologic mechanisms that have similar clinical presentations. The former conditions are usually called drug-induced skin diseases, whereas the latter conditions are termed "dermatosis-like drug eruptions." Both types are great imitators in dermatologic practice and can be easily misdiagnosed as other diseases or lead to unrecognized causative agents.
