Abstract

We herein describe the first case of desquamative interstitial pneumonia (DIP) induced by waterproofing spray, which was proven by a surgical lung biopsy. A 45-year-old male smoker heavily used a waterproofing spray gas, and presented with chills and fever that was followed by progressive dyspnea. Because steroid pulse therapy did not improve his symptoms, he was referred to our hospital. High-resolution chest CT showed diffuse pan-lobular ground-glass opacities in both lungs. A video-assisted thoracoscopic lung biopsy revealed a DIP pattern. Acute short-time exposure to waterproofing spray can thus be a potential cause of DIP.
