ABSTRACT

Idiopathic lymphocytic interstitial pneumonia (LIP) is a rare benign lymphoproliferative lung disease that is characterized by the infiltration of lymphocytes, plasma cells, and other lymphoreticular cells along the interstitium and alveolar septa, which lead to serious consequences. It may be accompanied by other diseases or can be idiopathic. This study presents a patient with complaints of cough and shortness of breath who was diagnosed with idiopathic LIP on the basis of radiographic and lung biopsy findings.
