RESUMO
We herein describe the case of a 63-year-old man who died from relapsed epidermal growth factor receptor gene (EGFR) exon 19 deletion lung adenocarcinoma treated with erlotinib. According to the autopsy results, he was confirmed to have small cell carcinoma without the EGFR T790M mutation in his pancreas and left kidney metastatic specimens, while the adenocarcinoma metastatic lesion in his right kidney had the EGFR T790M mutation; both retained the somatic EGFR exon 19 deletion. We herein report an autopsy case of resistance to an EGFR tyrosine kinase inhibitor via small cell carcinoma transformation and the EGFRT790M mutation in separate metastatic organs.

Acute lung injury during pregnancy results in morbidity and mortality in both the mother and the fetus. Pneumocystis jirovecii pneumonia (PCP) is a rare disease but may occur in pregnant immune-suppressed women. Here, we describe a case of acute lung injury due to PCP and alveolar hemorrhage in a pregnant woman who was a human T lymphotropic virus type-1 (HTLV-1) carrier. PCP should be considered in the differential diagnosis of pulmonary complications during pregnancy in HTLV-1 endemic areas.
