Abstract
|
|
|
Lymphocytic interstitial pneumonia (LIP) is a rare disorder characterized by a diffuse infiltration of the alveolar space, interstitium by lymphocytes, plasma cells, and reticuloendothelial cells. Although its etiology is unknown, LIP has been associated with autoimmune disorders and with viral infections. Because it¡¯s clinical and radiographic features are nonspecific, a confirmatory diagnosis is performed by open lung biopsy. A 59-year-old female presented dry cough, which had been present for 1 month. On initial findings of multifocal consolidation at the right middle lobe on both lower lobes in chest radiography, the first diagnosis of cryptogenic organizing pneumonia was suggested. On open lung biopsy, LIP was diagnosed. The patient had no autoimmune disease, viral infection or monoclonal gammopathy. After 3 months of corticosteroid treatment, the patient experienced improved symptoms, reduced abnormalities on chest radiography, and improved pulmonary function testing.
