Disseminated Nocardiosis with Lung, Liver and Spleen Abscesses in Sweet Syndrome: A Case Report.

Hepatic abscesses are rarely encountered in disseminated nocardia infections. We report a rare case of idiopathic Sweet syndrome (SS) who responded well to steroid therapy. However, he developed multiple abscesses in the lung, liver and spleen after 6 months of systemic steroid therapy. The culture result from liver abscess and sputum was diagnostic of disseminiated nocardiosis. Intravenous sulfamethoxazole/trimethoprim was given and follow-up computed tomography (CT) scan revealed resolution of abscess. To conclude, nocardiosis should be suspected as a likely cause of lung, liver and spleen abscesses in patients undergoing long-term steroid treatment. A high index of clinical suspicion in patients with defects in cell-mediated immunity and prompt management by appropriate image studies are needed to prevent delay in diagnosis.
