An inflammatory component is commonly seen on Pap smears from pregnant women [35] and does not appear to be a risk for subsequent preterm birth. [36] After childbirth, it is recommended to wait 12 weeks before taking a Pap test because inflammation of the cervix caused by the birth interferes with test interpretation. [37]
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]
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.
The cause of CIN is chronic infection of the cervix with HPV, especially infection with high-risk HPV types 16 or 18. It is thought that the high-risk HPV infections have the ability to inactivate tumor suppressor genes such as the p53 gene and the RB gene, thus allowing the infected cells to grow unchecked and accumulate successive mutations, eventually leading to cancer.
Pap stain. Endometrial adenocarcinoma (carcinoma at left in image) with squamous differentiation evidenced as necrotic “ghost cells” of keratinocytes at right in image, leaving pink keratin as well as clear spaces at the prior locations of the cell nuclei.
IELs have heightened activated status that can lead to inflammatory disease such as IBD, promote cancer development and progression, [12] or become the malignant cells in enteropathy-associated T-cell lymphoma, a lymphoma that is a complication of celiac sprue.
An inflammatory cytokine is a type of cytokine (a signaling molecule) that is secreted from immune cells and certain other cell types that promotes inflammation. Inflammatory cytokines are predominantly produced by T helper cells ( T h ) and macrophages and involved in the upregulation of inflammatory reactions. [ 1 ]
A giant cell (also known as a multinucleated giant cell, or multinucleate giant cell) is a mass formed by the union of several distinct cells (usually histiocytes), often forming a granuloma. [ 1 ] Although there is typically a focus on the pathological aspects of multinucleate giant cells (MGCs), they also play many important physiological roles.
