Abstract:
Topical medications are frequently neglected as the potential cause of systemic drug reactions. In this case report, a patient with a maculopapular eruption attributed to a drug hypersensitivity reaction was submitted to skin patch tests in order to clarify the drug implicated. Incidentally, a positive reaction to cinchocaine was observed. With the ulterior confirmation of the application of an antihemorrhoidal ointment containing cinchocaine, which was omitted during the initial anamnesis, the diagnosis of systemic contact dermatitis to cinchocaine was made.
