title: [Pneumocystis jiroveci infection associated with organizing pneumonia in a kidney transplant patient].
abstract: The authors report the association of organizing pneumonia (OP) and a Pneumocystis jiroveci infection in a woman who benefited from a kidney transplant 13 years before and was under corticoids, cyclosporine and mycophenolate mofetil. The diagnosis was based on progressive dyspnoea with fever with an alteration in the general state associated with diffuse micronodular pneumopathy suggesting bronchiolitis. The conformation was obtained by the analysis of the alveolar bronchial washings and the histological examination of the distal biopsies revealing endo-alveolar vegetant fibromas. Transbronchial biopsies may be used for the diagnosis and thereby, avoid an invasive surgical pulmonary biopsy. The aetiology of OP may be related to the immunosuppressant treatment or infection by Pneumocystis jiroveci. The evolution in this case was favourable with trimethoprime and sulfamethoxazole associated with a transient increase in the corticoid treatment. This association is rarely described in patients undergoing solid organ transplants.
