A review of all cases of nocardiosis in a large hospital in South Florida over the last 6 years was conducted. There were 25 cases of nocardiosis and 76% of them were also infected with HIV. Of the HIV infected patients, all of them had CD4 counts less than 100 cells/mm(3) and most cases were localized in the lungs.

An 86-year-old woman with a 6-year history of bronchiectasis and recurrent pneumonia in the right lung presented to our hospital several weeks' bloody sputum. Imaging studies showed ground-glass infiltrative opacities lung, Nocardia species were repeatedly isolated on sputum culture testing. Genetic testing identified wallacei, which was resistant sulfamethoxazole/trimethoprim. Therefore, patie...

Ectopic adrenocorticotropic hormone (ACTH) syndrome (EAS) associated with nocardiosis is rare, and little information is available regarding its clinical characteristics. In this study, the case of a 35-year-old male patient who showed significant cushingoid features and had a cough with yellow phlegm for 1 month is described. Pulmonary computed tomography (CT) scanning and 18F-fluorodeoxygluco...

BACKGROUND Nocardiosis primarily occurs in the setting of immunocompromising conditions. However, it may also occur in immunocompetent patients. We described computed tomography features of pulmonary nocardiosis and compared immunocompetent and immunocompromised patients. MATERIAL/METHODS CT images of 25 patients (Mean age of 39.5 years; 76% male) with pulmonary nocardiosis proved by bronchoa...

Nocardiosis is a rare bacterial infection of either the lungs (pulmonary) or body (systemic) that usually affects immunocompromised individuals. It is caused by Gram-positive, aerobic actinomycetes of the Nocardia genus. Multiple high-density sheet shadows in both lungs along with nodules or cavities are the most common presentations of nocardiosis, whereas a large pulmonary mass is considered ...

Nocardiosis is an infrequent but serious pulmonary infection caused by Gram-positive aerobic actinomycetes. In this paper, we report on a 48-year-old patient with pleuropulmonary nocardiosis and cirrhosis due to chronic hepatitis C virus infection treated with triple antiviral treatment complicated by prolonged neutropenia.
