Respiratory nocardiosis remains a diagnostic challenge. The disease is rare in immunocompetent individuals. Early identification and appropriate treatment results in decreased mortality in these patients. Case presentation: Herein we report a case of pulmonary nocardiosis due to Nocardia otitidiscaviarum in a 56 year old diabetic male with COPD. The patient complained of cough for 2 weeks. Respiratory samples (sputum, BAL) were sent for microbiological analysis. On routine staining, gram positive branching filamentous bacteria were seen. Modified Ziehl Neelsen staining confirmed the presence of acid fast bacilli resembling Nocardia. Further analysis by MALDI TOF identified the species to be Nocardia otitidiscavarium. The patient was treated with combination therapy of cotrimoxazole and ciprofloxacin and had a good recovery. Conclusion: Prompt identification and reporting of Nocardia aids in the clinical prognosis of the patients.
