A Case of Nonspecific Interstitial Pneumonia Associated with Systemic Lupus Erythematosus / 결핵

ABSTRACT

Systemic lupus erythematosus frequently has thoracic involvement among connective tissue diseases. One of the pleuropulmonary manifestations is diffuse interstitial lung disease including nonspecific interstitial pneumonia(NSIP). NSIP if a newly classified disease among interstitial lung diseases. Systemic lupus erythematosus has a better prognosis than usual interstitial peumonia(UIP) and responds well to steroids. In this report, a 34 year-old woman who complained of a dry cough, and exertional dyspnea for 2 months is described. The chest X-ray showed fine reticular opacities and a mild honeycomb appearance in both basal lungs. High resolution computed tomography(HRCT) showed bilateral patchy areas of ground-glass attenuation and a mild honeycomb appearance in the subpleural of both the lower and the middle portion of the lung fields. An open lung biopsy showed prominent lymphocytic interstitial inflammation and fibrosis with small are as with a honeycomb appearance. This case was diagnosed as NSIP associated with systemic lupus erythematosus and was managed with oral steroids. Here we report a case of nonspecific interstitial pneumonia associated with systemic lupus erythematosus confirmed by HRCT and an open lung biopsy with a review of the relevant literature.
