Drug-induced hypersensitivity syndrome in an ANA-negative, anti-dsDNA-negative systemic lupus erythematosus patient

A 50-year-old female presented with rash and multi-organ toxicity after intake of several antibiotics. This unmasked an elderly-onset, non-drug-induced seronegative systemic lupus erythematosus (SLE)which was confirmed by lupus band test (LBT)and skin biopsy staining. This patient presented with the rare combination of drug-induced hypersensitivity syndrome (DIHS)and SLE.
