Case Report: Rare Presentation of Nocardia cyriacigeorgica Pleural Nocardiosis in a Kidney Transplant Patient

This rare case of pleural nocardiosis caused by Nocardia cyriacigeorgica in a kidney transplant recipient highlights diagnostic challenges, as the presentation mimicked malignancy. High clinical suspicion is crucial when standard antimicrobial therapy fails in immunosuppressed patients. Early diagnosis through tissue culture and aggressive treatment with appropriate antibiotics, combined with immunosuppression adjustment, led to successful outcomes. This report adds valuable insights to the limited literature on this emerging pathogen in transplant recipients and emphasizes the importance of considering rare opportunistic infections in the differential diagnosis.
