Lichenoid drug eruptions often have polymorphic, atypical presentations. In the case presented in our article, the patient also had violaceous papules and plaques on her palms and upper back. These lesions lacked the characteristic changes of lichen planus and raised the differential diagnosis of drug-induced subacute lupus erythematous (angiotensin-converting enzyme inhibitors are commonly responsible), lupus erythematosus/lichen planus overlap syndrome, interstitial granulomatous drug reaction, and interstitial granulomatous dermatitis due to a drug (angiotensin-converting enzyme inhibitors are commonly implicated).
