[Non-specific interstitial pneumonia : a rare clinical entity in adolescents].

: Non-specific Interstitial Pneumonia (NSIP) is an anatomo-clinical entity within the group of Diffuse Infiltrative Pulmonary Diseases (DPID). It is very rarely found in pediatrics. Main symptoms are dry cough and dyspnea. Bronchoalveolar lavage and biology are non specific. The thoracic CT scan suspects the diagnosis, but histological examination of a lung biopsy remains the reference examination and makes the diagnosis highly probable according to the ATS / ERS criteria. An autoimmune assessment should be performed because NSIPs are often associated with connective tissue disease or may even be the first sign of connectivitive tissues diseases. The treatment of the acute phase is mainly based on the administration of corticosteroids and the prognosis is generally good. In this article, we describe the management of NSIP, based on a pediatric clinical case.
