A solitary pulmonary nodule due to Mycobacterium gordonae

Mycobacterium gordonae is rarely pathogenic in humans. In this case it was cultured from the tissue of a resected pulmonary nodule in an immunocompetent patient. One year after completing 12 months of chemotherapy, the patient remains disease free. Atypical mycobacterium should be considered in the differential diagnosis of solitary pulmonary nodules.
