Idiopathic interstitial pneumonias are at present classified as one of four types: usual, nonspecific, acute, or desquamative. The acute form has the worst prognosis, followed by the usual and the nonspecific form; it is in desquamative cases that prognosis is best. At high-resolution CT, usual interstitial pneumonia, the most frequent type, manifests as patchy subpleural areas of ground-glass attenuation, irregular linear opacity, and honeycombing, which the nonspecific type, the second most frequent, appears as subpleural patchy areas of ground-glass attenuation with associated areas of irregular linear opacity. Acute interstitial pneumonia demonstrates extensive bilateral airspace consolidation and patchy or diffuse bilateral areas of ground-glass attenuation in middle and lower lung zones.

Idiopathic pulmonary fibrosis (IPF) is strongly associated with lung cancer compared with the general population. However, other types of idiopathic interstitial pneumonia (IIP) are rarely associated with lung cancer. We describe a case of a primary lung cancer associated with IIP other than IPF, which was considered to be nonspecific interstitial pneumonia (NSIP), and NSIP disappeared spontaneously after treating the primary lung cancer.

Diffuse interstitial lung diseases (DILDs) are a heterogeneous group of non-neoplastic, noninfectious disorders resulting from damage to the lung parenchyma, and present with similar clinical features. There has been difficulty in the classification and diagnosis of DILDs because they contain more than 200 diseases. The American Thoracic Society and European Respiratory Society (ATS/ERS) expert meeting have proposed to classify DILDs into 4 categories, (1) known cases, (2) granulomatous diseases, (3) idiopathic interstitial pneumonias (IIPs), and (4) other forms. Among them, IIPs also comprise several different clinicopathological entities; however, it was previously thought to be a single disease, idiopathic pulmonary fibrosis (IPF), and resulted in a lot of confusion. Therefore, the ATS/ERS consensus classification provided a standardized nomenclature and diagnostic criteria of IIPs. IIPs are now classified into seven clinicopathologic entities; IPF, nonspecific interstitial pneumonia (NSIP), cryptogenic organizing pneumonia (COP), acute interstitial pneumonia (AIP), respiratory bronchiolitis-associated interstitial lung disease (RB-ILD), desquamative interstitial pneumonia (DIP), and lymphoid interstitial pneumonia (LIP). Because of these complexities, it is not easy to make the diagnosis of the patients with DILDs. This review will present a brief overview of DILDs and summary of diagnostic approaches with highlights on several specific items. An important thing to emphasize is the diagnosis of DILDs should be multi-disciplinary and the final diagnosis should be rendered only after reviewing all of the clinical, radiological, and pathological data of the patient. The more detailed description and discussion on some common diseases of DILDs will be followed by different authors.

Nonspecific interstitial pneumonia (NSIP) was first described as a new category of idiopathic interstitial pneumonia in 1994. This is a disease with a more insidious onset and has a chronic course. The histological findings are unusual for other idiopathic interstitial pneumonia cases (usual interstitial pneumonia, diffuse interstitial pneumonia, and acute interstitial pneumonia). In contrast to NSIP, acute interstitial pneumonia (AIP) has an acute onset and a fulminant course with the rapid development of respiratory failure. A pathological examination demonstrated characteristic diffuse interstitial fibrosis, hyaline membranes, thrombi, and architectural derangement. Here we report a 48-year-old woman who was diagnosed pathologically NSIP, but with a rapid progressive course similar to AIP.

Usual interstitial pneumonia (UIP) is one type of idiopathic interstitial pneumonia, characterized by its poor prognosis and gradual deterioration of clinical course. So it is important to distinguish UIP from other interstitial pneumonia. Defi nitive histological diagnosis of UIP requires lung biopsy. The criteria for diagnosis of UIP in the absence of a surgical lung biopsy were recently defi ned. We report a case of 75-year-old man who was diagnosed as bronchopneumonia with chief complaint of fever, dyspnea on fi rst visit, then fi nally diagnosed as UIP through the remaining of chest abnormality after treatment.
