چکیده

The pathological and molecular classification of lung cancer has become substantially more complex over the past decade. For diagnostic purposes on small samples, additional stains are frequently required to distinguish between squamous cell carcinoma and adenocarcinoma. Subsequently, for advanced nonsquamous cell nonsmall cell lung carcinoma (NSCLC) patients, predictive analyses on epidermal growth factor receptor, anaplastic lymphoma kinase and ROS1 are required. In NSCLCs negative for these biomarkers, programmed death ligand-1 immunohistochemistry is performed. Small samples (biopsy and cytology) require "tissue" management, which is best achieved by the interaction of all physicians involved.

The role of macrophages in interstitial lung diseases: Number 3 in the Series "Pathology for the clinician" Edited by Peter Dorfmüller and Alberto Cavazza.

The finding of collections of macrophages/histiocytes in lung biopsy and bronchoalveolar lavage is relatively common in routine practice. This morphological feature in itself is pathological, but the exact clinical significance and underlying disease should be evaluated together with clinical data, functional respiratory and laboratory tests and imaging studies.Morphological characteristics of ...

Background and purpose: Several studies have been carried out on re-cut and de-stained sections regarding prostate biopsies and cytologic specimens of squamous cell carcinoma. However, few studies on lung biopsy are done. Due to small size of lung biopsies and for the prevention of lung rebiopsy, in this study P63 staining intensity between re-cut and de-stained slides of patients, specimens ...
