Drug Rash with Eosinophilia and Systemic Symptoms to antituberculosis treatment.

Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) syndrome reflects a serious hypersensitivity reaction to drugs. This syndrome is an uncommon adverse reaction due to antituberculosis drugs and is sometimes difficult to identify the culprit agent. We report a case of a 45-year-old woman who received combined antituberculosis drugs (RHZE) for lymph node tuberculosis. Clinical manifestations included fever, dyspnea, rash, hypereosinophilia and visceral involvement (liver involvment). After symptom resolution and biology normalization, anti-tuberculosis drugs were reintroduced successively one after another. Systemic symptoms reappeared with the four anti-tuberculosis drugs. The clinical outcome was favorable with second line antituberculosis treatment.
