Background: Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome is a rare, potentially life-threatening hypersensitivity reaction characterized by skin rash, fever, eosinophilia, and multi-organ involvement. Although pulmonary complications are uncommon, they can significantly impact prognosis. Case Presentation: Here, we present a 6-year-old male with antibiotic-induced DRESS syndrome complicated by pleural effusion and pneumonitis. The patient was treated successfully with systemic corticosteroids and intravenous immunoglobulin following multidisciplinary evaluation. Conclusion: Pulmonary involvement in DRESS is frequently mistaken for pneumonia. This case highlights the importance of recognizing pulmonary involvement in DRESS syndrome and differentiating it from bacterial pneumonia, as misdiagnosis may lead to delayed corticosteroid treatment and unnecessary antibiotic use.
