Squamous metaplasia is a benign non-cancerous change (metaplasia) of surfacing lining cells (epithelium) to a squamous morphology.

Likewise, what is cervical squamous metaplasia?

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.

Also Know, are Metaplastic cells cancerous? Metaplasia - Metaplasia is generally described as a process of cell growth or cell repair that is benign (not cancerous). This process normally occurs in unborn babies, during adolescence, and with the first pregnancy.

Also asked, what does squamous metaplasia on a Pap smear mean?

Squamous metaplasia, the process by which mature, non-squamous epithelium is replaced by stratified squamous epithelium, is a well-described phenomenon in the endocervical canal of both women and laboratory animals. In the human cervix, this process has been shown to develop in stages.

Is squamous metaplasia reversible?

Thus, there is metaplasia of normal respiratory laryngeal epithelium to squamous epithelium in response to chronic irritation of smoking. The two forms of cellular transformation that are potentially reversible, but may be steps toward a neoplasm, are: Metaplasia is reversible when the stimulus for it is taken away.

Are squamous metaplastic cells normal?

Squamous Metaplastic Cells
These metabolically active cells are often the site where abnormalities occur. Throughout a woman's lifetime, the transformation zone regresses from the ectocervix and up into the endocervical canal.

What does it mean when endocervical and/or squamous metaplastic cells are present?

Endocervical and metaplastic cells: comparison of endocervical and metaplastic cell number in Papanicolaou smears with and without squamous intraepithelial lesion. CONCLUSION: Women with smears containing endocervical cells are not at greater risk for SIL than those with smears lacking these cells.

What are squamous cells?

Cancer that begins in squamous cells. Squamous cells are thin, flat cells that look like fish scales, and are found in the tissue that forms the surface of the skin, the lining of the hollow organs of the body, and the lining of the respiratory and digestive tracts. Also called epidermoid carcinoma.

What is high grade squamous intraepithelial lesion?

High-grade squamous intraepithelial lesion (HGSIL) is a type of precancerous changes in the cervix. This is when you have a lot of precancerous cells, which look very different from normal cells. These changes involve only cells on the surface of the cervix. “Cervical Cancer: Screening.”

What is squamous cell carcinoma?

Squamous cell carcinoma (SCC) is the second most common form of skin cancer. It's usually found on areas of the body damaged by UV rays from the sun or tanning beds. Sun-exposed skin includes the head, neck, chest, upper back, ears, lips, arms, legs, and hands. SCC is a fairly slow-growing skin cancer.

What is atypical squamous metaplasia?

Atypical squamous metaplastic (ASM) cells are associated with eventual development of high-grade squamous intraepithelial lesions (SILs) in many cases. In other words, atypical immature squamous metaplastic cells are more likely to be associated with SIL compared with atypical mature squamous metaplasia.

What does it mean when Metaplastic cells are present?

Metaplasia (Greek: "change in form") is the transformation of one differentiated cell type to another differentiated cell type. The change from one type of cell to another may be part of a normal maturation process, or caused by some sort of abnormal stimulus.

Are endocervical cells cancerous?

Cervical cell changes
These early cell changes may be precancerous. This means there is a lesion (area of abnormal tissue) that is not cancer but may lead to cancer. Cervical cell changes are often caused by certain types of the human papillomavirus (HPV).

What is the difference between dysplasia and metaplasia?

Metaplasia (Greek: "change in form") is the reversible replacement of one differentiated cell type with another mature differentiated cell type. Metaplasia is not synonymous with dysplasia and is not directly considered carcinogenic.

What does it mean when endocervical component present?

The presence of endocervical component (ECs) on cervical smears is considered essential for determining the adequacy of the Pap smear. The absence of an endocervical component in a negative smear suggests that a repeat Pap smear should be taken.

What can cause inflammation in the cervix?

Cervicitis is an inflammation and irritation of the cervix. Symptoms of cervicitis can be similar to vaginitis, with vaginal discharge, itching or pain with intercourse. Cervicitis can be caused by a sexually transmitted infection. Most common are chlamydia and gonorrhea.

What causes metaplasia?

pylori infection may be a cause of intestinal metaplasia. The exact cause of intestinal metaplasia is still uncertain. Some healthcare professionals believe an H. pylori infection causes intestinal metaplasia, but there is also a range of risk factors that may increase the risk of developing it.

What does inflammation on Pap smear mean?

Inflammation. If inflammation (redness) is present in the cells on the Pap smear, it means that some white blood cells were seen on your Pap smear. If the Pap smear showed that the inflammation is severe, your doctor may want to find the cause, such as an infection.

Does HPV cause inflammation?

Immune evasion is an essential aspect of HPV persistence and is also essential for the development of ICC. Once established, persistent HPV infection leads to changes in the release of proinflammatory cytokines, which in turn may alter the infiltration of immune cells, causing inflammation.

What causes abnormal squamous cells?

Atypical squamous cells of undetermined significance is the most common abnormal finding in a Pap test. It may be a sign of infection with certain types of human papillomavirus (HPV). It may also be a sign of a benign (not cancer) growth, such as a cyst or polyp or, in menopausal women, of low hormone levels.
