Case Reports[A case of systemic sclerosis associated with interstitial pneumonia with various autoantibodies: improvement by intravenous cyclophosphamide therapy].
A 41-year-old woman was admitted to Tokyo Women's Medical College Aoyama Hospital in January 1994. She presented cough and dyspnea in September 1991. The diagnosis of interstitial pneumonia was made based on TBLB. ⋯ After the third infusion, respiratory symptoms, pulmonary function test values, findings of chest X-ray and CT scan were improved without adverse drug effects. Intravenous cyclophosphamide therapy seems to be useful in this case. The efficacy of Intravenous cyclophosphamide therapy in the treatment of the interstitial pneumonia associated with systemic sclerosis was discussed.

Lymphoid interstitial pneumonitis (LIP) involves a clinicopathologic pattern of pulmonary disease characterized by diffuse interstitial reactive lymphoid infiltrates. In adults, it occurs most commonly in autoimmune diseases, such as Sjögren's syndrome (0.9% of these patients) and primary biliary cirrhosis, whereas in children it is usually seen in HIV infection. Dysproteinemias (hyper- and hypogammaglobulinemia) are found in more than 60% of patients. ⋯ These patterns may be difficult to differentiate from each other. It appears that LIP sometimes evolves to lymphoma; the frequency of this evolution is probably low but is difficult to assess because low-grade lymphomas may mimic LIP. A relatively high frequency of LIP patients have Epstein-Barr virus DNA in their lungs but not all patients with LIP show this finding, suggesting other possible etiologies.

Comparative Study
Disease progression in usual interstitial pneumonia compared with desquamative interstitial pneumonia. Assessment with serial CT.
To determine the outcome of areas of ground-glass attenuation and assess disease progression on serial high-resolution CT (HRCT) scans of patients with biopsy specimen-proved usual interstitial pneumonia (UIP) and desquamative interstitial pneumonia (DIP). ⋯ In patients with UIP, areas of ground-glass attenuation usually increase in extent or progress to fibrosis despite treatment. Areas of ground-glass attenuation in most patients with DIP remain stable or improve with treatment.
