Examples of epithelial dysplasia include cervical intraepithelial neoplasia – a disorder commonly detected by an abnormal pap smear) consisting of an increased population of immature (basal-like) cells which are restricted to the mucosal surface, and have not invaded through the basement membrane to the deeper soft tissues.
Non-small-cell lung cancer (NSCLC), or non-small-cell lung carcinoma, is any type of epithelial lung cancer other than small-cell lung cancer (SCLC). NSCLC accounts for about 85% of all lung cancers. [1] [2] [3] As a class, NSCLCs are relatively insensitive to chemotherapy, compared to small-cell carcinoma.
Urine typically contains epithelial cells shed from the urinary tract, and urine cytology evaluates this urinary sediment for the presence of cancerous cells [2] [3] from the lining of the urinary tract, and it is a convenient noninvasive technique for follow-up analysis of patients treated for urinary tract cancers.
Normal squamous cells Dysplastic cells. Dysplasia is any of various types of abnormal growth or development of cells (microscopic scale) or organs (macroscopic scale), and the abnormal histology or anatomical structure(s) resulting from such growth. [1] Dysplasias on a mainly microscopic scale include epithelial dysplasia and fibrous dysplasia ...
This system provides a uniform way to describe abnormal epithelial cells and determine specimen quality, thus providing clear guidance for clinical management. These abnormalities were classified as squamous or glandular and then further classified by the stage of dysplasia: atypical cells, mild, moderate, severe, and carcinoma. [13]
Epithelial cells form the lining of the urinary tract. Three types may occur in urine: squamous epithelial cells, transitional epithelial cells and renal tubular epithelial cells. Some laboratories do not distinguish between the three types of cells and simply report "epithelial cells" in general. [104]
LCC is categorized as a type of NSCLC (non-small-cell lung carcinoma) that originates from epithelial cells of the lung. LCLC is histologically characterized by the presence of large, undifferentiated cells that lack distinctive features of either squamous cell carcinoma or adenocarcinoma (other types of cancers).
One example of pathological irritation is cigarette smoke, which causes the mucus-secreting ciliated pseudostratified columnar respiratory epithelial cells that line the airways to be replaced by stratified squamous epithelium, or a stone in the bile duct that causes the replacement of the secretory columnar epithelium with stratified squamous ...
