What is metaplasia of the cervix?
What is metaplasia of the cervix?
Squamous metaplasia in the cervix refers to the physiological replacement of the everted columnar epithelium on the ectocervix by a newly formed squamous epithelium from the subcolumnar reserve cells. The region of the cervix where squamous metaplasia occurs is referred to as the transformation zone.
Can squamous metaplasia become cancer?
Endocervical squamous metaplasia There is no risk of malignant transformation for squamous metaplasia. Nevertheless, the metaplastic change within the endocervix may increase the risk for human papilloma virus infection (Hwang et al., 2012), which is a risk factor for cervical cancer.
Is cervical metaplasia precancerous?
Process of Cervical Changes The Pap test is taken from this area because this where dysplasia (pre-cancer) and cancer most often arise. Two common changes in cells are metaplasia and dysplasia. Metaplasia – Metaplasia is generally described as a process of cell growth or cell repair that is benign (not cancerous).
What is tubal metaplasia?
Introduction. Tubal (or ciliated cell) metaplasia of the endometrium is characterized by ciliated columnar cells with bland round nuclei and eosinophilic cytoplasm, similar to the cells normally seen lining the fallopian tube [1.
Is metaplasia normal?
Metaplasia can also occur as a normal physiologic response. An example of physiologic metaplasia is the squamous metaplasia that occurs in the uterine cervix during the menstrual cycle as the squamocolumnar junction migrates across the transformation zone (Fig. 1-13).
Is squamous metaplasia of cervix precancerous?
Squamous metaplasia is a benign non-cancerous change (metaplasia) of surfacing lining cells (epithelium) to a squamous morphology.
Can metaplasia be cured?
Currently, the most effective treatment is to remove the H. pylori infection completely. This removal is done in combination with the use of antioxidant agents. Studies have shown this to be an effective way of trying to reverse intestinal metaplasia.
What are the causes of metaplasia?
Metaplasia is the replacement of one differentiated somatic cell type with another differentiated somatic cell type in the same tissue. Typically, metaplasia is triggered by environmental stimuli, which may act in concert with the deleterious effects of microorganisms and inflammation.
Is Tubal metaplasia bad?
Long-term outcome. Atypical tubal metaplasia is worrisome in endometrial biopsy and curettage specimens, as it displays a superficial resemblance to invasive or intraepithelial serous carcinoma. Uterine serous carcinoma is well known for exhibiting aggressive behavior.
What is Tubal metaplasia of the uterine cervix?
Eleven cases of tubal metaplasia of the uterine cervix are presented. These are characterized histologically by architecturally normal endocervical glands containing ciliated or clear cells, nonciliated cells, and intercalary or peg cells, resembling normal tubal mucosa. Transitions from normal to c …
Can tubal metaplasia be reversed with endometrial biopsy?
Endometrial biopsy 3/3/15 results – tubal metaplasia and scant sample, so d&c hysteropscopy 04/14/15 results show no tubal metaplasia can it reverse? Can: Metaplasia is reversible by definition. However it is more likely that the scant sample on biopsy was insufficient for a definitive diagnosis.
How serious is leukoplakia of the cervix?
Before carrying out IVF, leukoplakia is preliminarily subjected to treatment without fail. If the disease is not treated, the consequences of leukoplakia of the cervix can be serious: first of all, the appearance of atypical cells, which is the beginning of malignancy of the process.
Is metaplasia of the endometrium reversible?
Can: Metaplasia is reversible by definition. However it is more likely that the scant sample on biopsy was insufficient for a definitive diagnosis. Insignificant find: Tubal metaplasia is an insignificant finding in endometrial tissue.
