Diffuse alveolar hemorrhage complicating acute exacerbation of IPF.

An 83-year-old man with a history of interstitial lung disease (ILD) presented with a 1-week history of progressive dyspnea. Computed tomography of the chest revealed right lung-predominant, diffuse, ground glass opacities superimposed upon reticular opacities. Despite methylprednisolone pulse therapy under a diagnosis of acute exacerbation (AE) of ILD, lung involvement and renal dysfunction worsened and disseminated intravascular coagulation developed.

Miliary lung metastases from non-small cell lung cancer with Exon 20 insertion: A dismal prognostic entity: A case report.

Miliary lung metastases have been reported to be frequently observed in nοn-small cell lung cancer (NSCLC) with major EGFR mutations, which consist of exon 19 deletion and exon 21 L858R. However, it remains undetermined whether NSCLC with minor EGFR mutations possesses characteristics similar to those with major EGFR mutations. In the present study, two cases of miliary lung metastases from NSCLC with exon 20 insertion were reported.
