2.The diagnosis should be differentiated with benign lymphoepithelioma, metastasis or infiltrated poorly differentiated squamous cell carcinoma and malignant lymphoma.
4.Neoplasms have rarely been reported in lesions of lupus erythematosus (LE) and have included basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and atypical fibroxanthoma.
12.Wearing sunscreen helps protect against the development of all three types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma.
13.In chronic laryngitis the normal columnar cells undergo dysplasia, which is when they transform into squamous epithelium to adapt to the chronic irritation.
14.Squamous cell cancers arise from squamous cells that undergo genetic mutations that either activate proto-oncogenes or inactivate tumor suppressor genes.
16.A second type of epithelium is non-keratinized stratified squamous epithelium, and it contains cells that don't produce much keratin, making this layer less tough.
18.Well-differentiated tumors with adenocarcinoma or squamous cell carcinoma morphology can be diagnosed by routine light microscopy, without the need for IHC.
19.Non-small-cell lung cancer (NSCLC), which includes adenocarcinoma, squamous cell carcinoma and large cell carcinoma, accounts for 80- 85% of all lung cancers.
