Interstitial pneumonia is a common and major comorbidity affecting the prognosis of patients with systemic sclerosis (SSc). However, there are few reported cases of SSc-rheumatoid arthritis (RA) overlap-associated interstitial pneumonia. We herein report a case in which the clinical behavior and histopathology of interstitial pneumonia with SSc-RA overlap syndrome was followed over a long clini...

A histologic feature of usual interstitial pneumonia is the presence of fibroblastic foci. As some patients with usual interstitial pneumonia and an underlying collagen vascular disease have a better prognosis we hypothesized that they would have fewer fibroblastic foci. Pathologists reviewed surgical lung biopsies from 108 patients with usual interstitial pneumonia (nine with collagen vascular...

Interstitial pneumonias have recently been associated with mutations in the gene encoding surfactant protein C (SFTPC). In particular, SFTPC mutations have been reported in a number of familial forms of pulmonary fibrosis and in infants with interstitial lung diseases. The present study searched for SFTPC mutations in adult patients with sporadic idiopathic interstitial pneumonia. In total, 35 ...

OBJECTIVE The objective of this study was to determine whether the various chronic cystic lung diseases can be differentiated on the basis of the pattern and distribution of abnormalities on high-resolution CT. MATERIALS AND METHODS High-resolution CT scans in 92 patients with chronic cystic lung diseases (18 with pulmonary Langerhans cell histiocytosis, 18 with pulmonary lymphangioleiomyomat...

  This study was carried out at the Razi Institute during 2005-2006 with inspecting 12168 lung tissue of slaughtered sheep and goats at the Ziaran Abattoir. Pneumonia were diagnosed in 282 cases and the affected lung tissue was collected and transferred to the Bacteriology and Pathology Departments for isolating of Pasteurella spp. and interpretation of histopathologic lesions. Pasteurella mult...

Collagen vascular disease is one of the most common causes of chronic infiltrative lung disease. Patterns of lung injury from collagen vascular disease include nonspecific interstitial pneumonia (NSIP), usual interstitial pneumonia, organizing pneumonia, bronchiectasis, obliterative bronchiolitis, and pulmonary arterial hypertension. The prevalence of each entity varies according to the specifi...

In patients with interstitial lung disease (ILD), the diagnosis of idiopathic interstitial pneumonia is usually made after excluding, among other conditions, connective tissue diseases (CTDs). Although in most patients with a CTD and respiratory symptoms, the systemic nature of the disease is obvious, the ILD-related manifestations in CTDs may often dominate the clinical picture or precede syst...

Idiopathic pulmonary fibrosis (IPF), which has the histological pattern of usual interstitial pneumonia (UIP), is a progressive interstitial lung disease with a poor prognosis. Idiopathic interstitial pneumonias with a histological pattern of nonspecific interstitial pneumonia (NSIP) have a better prognosis than UIP, and may present with a clinical picture identical to IPF. The authors hypothes...
