Micrograph of a clue cell (center), covered in bacteria, as compared to an unremarkable squamous cell at bottom left, and a neutrophil at bottom center. Pap stain Phase contrast microscopy of clue cells in a vaginal swab. Clue cells are epithelial cells of the vagina that get their distinctive stippled appearance by being covered with bacteria ...
ThinPrep pap smear with group of normal cervical cells on left and HPV-infected cells showing features typical of koilocytes: enlarged (x2 or x3) nuclei and hyperchromasia. A koilocyte is a squamous epithelial cell that has undergone a number of structural changes, which occur as a result of infection of the cell by human papillomavirus (HPV). [1]
For example, the most common cancer of the liver parenchyma ("hepato-" = liver), arising from malignant epithelial cells ("carcinoma"), would be called a hepatocarcinoma, while a malignancy arising from primitive liver precursor cells is called a hepatoblastoma.
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]
Squamous-cell carcinoma (SCC), also known as epidermoid carcinoma, comprises a number of different types of cancer that begin in squamous cells. [1] These cells form on the surface of the skin, on the lining of hollow organs in the body, and on the lining of the respiratory and digestive tracts .
D. Squamous cell carcinoma, infiltrating the stroma (middle and left in image), and HSIL (right in image) Epithelial dysplasia , a term becoming increasingly referred to as intraepithelial neoplasia , is the sum of various disturbances of epithelial proliferation and differentiation as seen microscopically.
They are classified according to the specific type of epithelial cells that are affected. [ 1 ] The most common epitheliomas are basal cell carcinoma and squamous cell carcinoma (skin cancers).
Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or lymph with abnormal cells. Cell division is a normal process used by the body for growth and repair. A parent cell divides to form two daughter cells, and these daughter cells are used to build new tissue or to replace cells that have died because of ...
