Pulmonary nocardiosis in an elderly man

815Diagnosis of Pulmonary Nocardiosis

Background. Pulmonary nocardiosis (PN) is an uncommon infection often seen in immunocompromised patients. Definitive diagnosis depends on identification of the organism by culture in a patient with a clinical presentation suggestive of PN. As Nocardia can grow slowly and other infections can present similarly in the immunocompromised patient, we sought to find the performance of respiratory sam...

Fulminating Pulmonary Nocardiosis.

Pulmonary nocardiosis mimicking tuberculosis

Pulmonary nocardiosis is an infrequent and severe infection due to Nocardia species, microorganisms that may behave both as opportunists and as primary pathogens. Diagnosis of pulmonary nocardiosis is frequently delayed and a high level of suspicion is required in patients with underlying diseases or chronic corticosteroid therapy. Hereby we are presenting a case of pulmonary nocardiosis mimick...

Cutaneous and pulmonary Nocardiosis in a patient with Pemphigus

Pemphigus is a chronic blistering mucocutaneous disease, classified in immunobullous skin diseases. Infections, particularly septicemia due to Staphylococcus aureus and Pseudomonas aeroginosa are the most common and dangerous disorders due to immunosuppressive therapy in this disease. Infection with nocardia is rare, so that only 6 cases have been reported yet. Herein, we report a 56-year-old m...

Pulmonary Mycobacterium intermedium disease in an elderly man with healed pulmonary tuberculosis.

A 76-year-old man with a history of pulmonary tuberculosis was found to be sputum smear positive for acid-fast bacilli. The 16S rRNA sequence identified the culture isolate as Mycobacterium intermedium, the pathogenicity of which has not been confirmed. Chemotherapy with isoniazid, rifampin, and ethambutol resulted in clinical improvement.
