Abstract
Cutaneous drug reactions are adverse reactions to medications that may present with different clinical features, ranging from localized to generalized lesions. In this report we describe a case of an unusual drug reaction, resembling the morphology of Sweet syndrome lesions. The patient had a psychiatric illness and was using thioridazine hydrochloride for one year. He developed infiltrated and grouped erythematous lesions on the elbows and knees three days after commencing multiple drugs (promethazine, haloperidol, mirtazapine and levomepromazine). After suspension of these four drugs and after the use of glucocorticoids, the patient had significant clinical improvement.
