Cutaneous nocardiosis in chronic renal insufficiency: Diagnostic and therapeutic considerations.

Nocardiosis remains a rare and often underdiagnosed bacterial infection, particularly in immunocompromised individuals. The case report by Zhang et al highlights the diagnostic and therapeutic challenges in managing Nocardia brasiliensis skin infection in a 93-year-old patient with chronic renal insufficiency. This editorial explores the importance of timely diagnosis, microbiological confirmation, and tailored antibiotic therapy. Emphasis is placed on the role of immune status evaluation, drug concentration monitoring, and the necessity of long-term antimicrobial therapy. Improved clinician awareness and adherence to evidence-based management protocols are essential to achieving better outcomes in nocardiosis cases.
