Abstract:
Background: We report a case of a 25-year-old female who presented with fever, rash
and general malaise.
Case Presentation: She was initially diagnosed and treated for peri-/myocarditis, but she deteriorated
quickly with the development of extensive bilateral consolidations for which she was mechanically
ventilated. Two weeks before admission, she took isotretinoin for less than a week for
disfiguring acne. Diagnosis of drug-induced acute eosinophilic pneumoniae (EP) was made after
excluding other causes of AEP. Even before starting steroid treatment, the patient improved significantly,
which was in alignment with the elimination of the active metabolite of isotretinoin.
Conclusion: The presented case underlines the importance of performing a thorough history and
consider recently started drugs as the cause of eosinophilic pneumoniae, even if they have not yet
been described as a known trigger of drug-induced EP.
