Desquamative Interstitial Pneumonia Complicated with IgG4-related Lung Disease
نویسندگان
چکیده
As an idiopathic interstitial pneumonia, desquamative interstitial pneumonia (DIP) is an uncommon form of interstitial lung disease and is considered to be a smoking- or dust inhalation-related interstitial pneumonia in the majority of cases. However, the details regarding immunoglobulin G4 (IgG4)-related lung disease remain unclear and controversial. We herein report the first case of DIP complicated with IgG4-related lung disease. Even if a patient has a smoking history, we emphasize the importance of exploring the association between DIP and IgG4-related lung disease to clarify the pathogenesis of these two disorders.

IgG4-related lung disease is commonly associated with autoimmune pancreatitis. Recently, isolated IgG4-related interstitial lung disease (ILD) without other organ involvement has newly been reported in two cases with clinical features of nonspecific interstitial pneumonitis (NSIP).We report the first case of an isolated IgG4-related ILD in a 78-year-old man with dry cough and dyspnea, whose cli...

Recently, great attention has been drawn to IgG4-related diseases such as autoimmune pancreatitis (AIP) sclerosing sialadenitis, retroperitoneum fibrosis, sclerosing cholangitis. IgG4-related diseases are characterized by high serum IgG4 concentrations, sclerosing inflammation with numerous IgG4-positive plasma cells, and steroid sensitivity irrespective of their organs of origin. In this repor...

Desquamative interstitial pneumonia (DIP) is a rare pattern of diffuse parenchymal lung disease known as one of the idiopathic interstitial pneumonias and is considered to be a smoking- or dust inhalation-related interstitial pneumonia in the majority of cases. This report presents the first case of DIP in which the pulmonary manifestation preceded the onset of rheumatoid arthritis. This case a...
متن کاملRespiratory bronchiolitis associated with interstitial lung disease and desquamative interstitial pneumonia.
This article explores issues of the diagnosis and management of respiratory bronchiolitis, respiratory bronchiolitis-associated interstitial lung disease, and desquamative interstitial pneumonia. These three diseases have common and overlapping features and sometimes are viewed as a continuum of smoking-induced disease, rather than as distinct and separate entities.
متن کاملDesquamative alveolar disease (desquamative interstitial pneumonia): case report.
Desquamative interstitial pneumonia is a disease characterized by massive alveolar cell proliferation and desquamation with sparse interstitial involvement. The reported case shows an unusually widespread radiographic reticulo-nodular image and abundant alveolar cells in the sputum. Functional studies reveal the expected diffusion defect with practically normal mechanical properties of the lung...
