title: Case-based discussion: Lymphocytic interstitial pneumonia a rare presentation in an immunocompetent adult male.
abstract: Lymphocytic interstitial pneumonia (LIP) is a rare form of interstitial lung disease usually associated with other systemic diseases; however, idiopathic cases are being reported. As per recent ATS/ERS 2013 guidelines, diagnostic criteria of clinical, radiological and histopathological for LIP is same as 2002 except some cystic changes on HRCT chest. Many cases diagnosed in the past as LIP now turn out to be NSIP; therefore as per new ATS/ERS classification whenever anybody report a case of LIP, NSIP should always be kept in mind as differential diagnosis. Here we present a case of LIP in an immunocompetent adult male presented with history of persistent dry cough and breathlessness on exertion, confirmed on HRCT chest and histopathologically, treated successfully with steroids.
