TL;DR: Assessments can make the murine LTx model a more useful tool for further mechanistic studies of CLAD pathogenesis, and grading of pathologic changes demonstrated variable severity of airway fibrosis, PF, acute rejection, vascular fibrosis and epithelial changes, similar to those seen in human CLAD.

TL;DR: The International Association for the Study of Lung Cancer Pathology Committee conducted a global survey for pathologists from January to May 2019, comprising multiple questions on preanalytical, analytical, and postanalytical conditions.

TL;DR: OS was longer for patients with TP53 and KRAS wild-type NSCLC who received chemotherapy for any stage compared with patients with KRAS, TP53 mutation, or double mutant tumors, but there was no significant difference in DFS/PFS.

TL;DR: Clinical presentations and histology of surgical biopsy-proven nonspecific interstitial pneumonia in 6 patients with clinical and radiologic progression, resulting in the need for rebiopsy or lung transplantation are described.

TL;DR: The steps involved in processing pathology specimens as they pertain to cross-contamination are reviewed; an approach covering how to troubleshoot and prevent tissue contaminants in a systematic and practical manner is shared; some examples from the authors' own experiences are presented; and their experience is compared to what is reported in the literature.
