A 40-year-old woman undergoing prednisolone and cyclosporine therapy for subcutaneous panniculitic T-cell lymphoma complained of a cough for a few weeks. A chest X-ray revealed bilateral diffuse granular shadows. Additionally, the patient was discovered to have multiple subcutaneous abscesses. Gram-stained smears of sputum and pus from the abscess showing branched gram-positive rods led to a diagnosis of pulmonary nocardiosis with dissemination to the lungs and subcutaneous tissues. Combination therapy consisting of sulfamethoxazole/trimethoprim and panipenem/betamipron produced rapid improvement of radiographic abnormalities. It is suggested that pulmonary nocardiosis should be considered in the differential diagnosis of diffuse granular shadows on chest X-rays, especially in immunocompromised patients.(Internal Medicine 41: 986-989, 2002)
