A Rare Etiology of Drug Rash in a Patient Receiving Anti-Tuberculosis Treatment

Abstract

Anti-tuberculosis medications can cause various side effects, including drug rash. When a patient on anti-tuberculosis treatment (ATT) develops rash, we usually stop all medicines, rechallenge the patient with medications individually, and find the offending agent. It should be mentioned that drug rash can be also a manifestation of other diseases. Herein, we report a case of tuberculosis who developed rash while on ATT regimen but was later diagnosed to be concomitantly suffering from leprosy.
