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 Nocardia. 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.
