squamous histo
precursor lesions (met>dys>insutu>)pleomorphic nuclei, keratin pearls, intracell bringe, TTF1- neg
adenocarcinoma
increasing incidence, most common in USA, kiwi smoking association, peripheral tumor
ademon histo
glands, mucin, TFF1 positive
small cell
very aggressive, large central mass, paraneoplastic (SIADH)… SMOKING
Histo small cell
small blue cells, stippled/molding, neuroendocrine, can be TFF1 positive
pleural tumors
usually mets (lung/BC), may cause pleural effusion, primary may be benign
pleural plaque
asbestosis, no clin signif
malignant mesothelioma
asbestos exposure, not smoking
mesothelioma histo
diffuse, rind like, firm/white
oral cavity tumors
