[Nocardiosis in a renal transplant recipient]

We report a unilateral pulmonary nocardiosis in a 51 years old male that received a renal allograft. The clinical picture appeared 68 days after transplantation and the culture of a bronchoalveolar lavage showed the presence of Nocardia asteroides. Cyclos-porine and azathioprine were discontinued and trimethoprim-sulphamethoxazole was started with a good clinical response. Afterwards, azathioprine was restarted and the patient is asymptomatic at the present moment.
