We discuss, using #kurt’snotes, the WHO system for respiratory cytology including #insufficient #inadequate #nondiagnostic, #benign, #atypical #suspiciousformalignancy #malignant.  We discuss the importance of #maximizingtissue and #preserving tissue for #egfr #ros1 #alk #pdl1 testing.  We discuss when a specimen is #insufficient or #inadequate or #nondiagnostic.  We discuss #normaltissue or #cytohistology including #bronchoepithelial cells, #squamous cells #squamousmetaplasia #gobletcells #alveolar #macrophages #cartilage #chondrocytes #bronchialglands.  We discuss benign lesions like #acuteinflammation from #neutrophils.  We discuss the #differentialdiagnoses including #infection #pneumonia #aspiration #infarction #vasculitis.  We discuss #granulomas and the ddx such as #infection #sarcoidosis #vasculitis #hypersensitivity #pneumonitis #drugreaction.  We discuss #lymphocytic interstitial pneumonia, #bechetdisease #lymphoma #organizingpneumonia.  We discuss eosinophilic inflammation such as #eosinophilic pneumonia #asthma #allergicbronchopulmonary #aspergillosis, #churg-strauss #parasitic disease.  We discuss #histiocytic conditions including #EVALI #amiodarone toxicity.  We discuss #pneumocystis #jirovecii.  We discuss. #alveolar #proteinosis, #curschmannspirals #charcot-ledyden crystals, #ferruginous bodies and #asbestos, #corpora #amylacea #amyloid.  We discuss reactive epithelial changes including #basalcell hyperplasia #reservecells #squamousmetaplasia #type2pneumocyte hyperplasia #chemotherapy #radiationchanges #radiation.  We discuss #nonsmallcellcarcinoma including #adenocarcinoma and use of #ttf1 #napsin.  We discuss #squamouscellcarcinoma, and use of #p40 and #ck5/6.  We discuss #carcinoid tumor and #atypicalcarcinoid as well as use of #synaptophysin #chromogranin #cd56 #insm1 and #ki67.  We discuss #smallcellcarcinoma and #largecellcarcinoma. We discuss briefly #nutcarcinoma #smarca4 #carcinosarcoma #pulmonaryblastoma #adenosquamous carcinoma #pleomorphic carcinoma #lymphomas #sarcomas, #salivarygland carcinomas including #mucoepidermoid carcinoma #adenoid cystic carcinoma #epithelial-myoepithelial carcinoma and #paraganglioma #mesothelioma and #germcell tumors
