Case in brief
A 47-year-old male with HIV and disseminated tuberculosis experienced recurrent maculopapular eruptions with mucosal involvement after exposure to multiple medications, including fluoroquinolones and rifampicin. Drug rechallenge confirmed these agents as culprits. The patient was effectively treated with systemic corticosteroids, intravenous immunoglobulin, and a careful reintroduction of non-culprit anti-tubercular drugs.
Diagnostic / clinical pearl
Clinicians should be cautious when reintroducing fluoroquinolones and rifampicin in immunocompromised patients, as they may provoke severe cutaneous reactions.
