The Diagnostic Challenges of Disseminated Nocardiosis in a Post-Renal Transplant Patient: A Case Report.

Disseminated nocardiosis is a rare, life-threatening infection, often misdiagnosed due to its resemblance to other conditions. We report a case of disseminated nocardiosis in a 62-year-old post-renal transplant patient presenting with pulmonary, hepatic, and pancreatic lesions. Despite multiple negative bacterial cultures, a histopathological examination of the liver revealed necrotizing granulomas with filamentous microorganisms, ultimately identified as . This case highlights diagnostic challenges and the importance of integrating microbiological, pathological, and radiographical findings to manage and diagnose disseminated nocardiosis infections in immunocompromised individuals.
