BACKGROUND: Among the first line Anti-Tubercular Drugs (ATDs), ethambutol has been rarely associated to cause drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome.
METHODS: A 34-year-old woman presented in an out-patient department of Dermatology with fever, skin eruptions, eosino- philia, hyperinflated lung fields and deranged liver enzymes after 35 days of the initiation of ATDs. The patient recovered completely after stopping ethambutol and administration of topical and sys- temic corticosteroids.
CONCLUSIONS: Based on the available evidences of de-challenge and re-challenge of suspected drugs, ethambutol was certainly implicated to cause DRESS syndrome.
