Another name for squamous epithelium is "pavement epithelium" because the cells are flat and resemble tiles on a floor.

Yes, squamous cells are flat and scale-like in shape when they are fully mature. These cells can be found in tissues that line surfaces, such as the skin, mouth, and respiratory tract. Squamous cells are important for providing protection and facilitating the exchange of substances across surfaces.

Squamous metaplasia itself is not dangerous, as it is a reversible change where one type of epithelial cell transforms into another type. However, in some cases, it can progress to more serious conditions such as squamous cell carcinoma if left untreated or if there are underlying risk factors present. Regular monitoring and addressing underlying causes can help prevent complications.

Finding 5-10 squamous epithelial cells in a urinalysis is within the normal range and can be considered a common finding due to contamination from the genital area during sample collection. It is important to assess other parameters in the urinalysis to interpret the results accurately. If other findings are normal and there are no associated symptoms, further evaluation may not be necessary.

Squamous cell skin cancer is a type of tumor that affects the skin.
Alternative NamesCancer - skin - squamous cell; Skin cancer - squamous cell; Nonmelanoma skin cancer - squamous cell; NMSC - squamous cell
Causes, incidence, and risk factorsSquamous cell cancer occurs when cells in the skin start to change. The changes may begin in normal skin or in skin that has been injured or inflamed. Most skin cancers occur on skin that is regularly exposed to sunlight or other ultraviolet radiation. Skin cancer is most often seen in people over age 50.
Squamous cell carcinoma in situ (also called Bowen's disease) is the earliest form of squamous cell cancer. The cancer has not yet invaded surrounding tissue. It appears as large reddish patches (often larger than 1 inch) that are scaly and crusted.
Actinic keratosis is a precancerous skin lesion. In rare cases it may become a squamous cell cancer.
Risks for squamous cell skin cancer include:
- Having light-colored skin, blue or green eyes, or blond or red hair
- Long-term, daily sun exposure (such as in people who work outside)
- Many severe sunburns early in life
- Older age
- A large number of x-rays
- Arsenic
- Chemical exposure
Squamous cell cancer spreads faster than basal cell cancer, but still may be relatively slow-growing. Rarely, it can spread (metastasize) to other locations, including internal organs.
SymptomsThe main symptom of squamous cell skin cancer is a growing bump that may have a rough, scaly surface and flat reddish patches.
The bump is usually located on the face, ears, neck, hands, or arms, but may occur on other areas.
A sore that does not heal can be a sign of squamous cell cancer. Any change in an existing wart, mole, or other skin lesion could be a sign of skin cancer.
Signs and testsYour doctor will check your skin and look at the size, shape, color, and texture of any suspicious areas.
If skin cancer is a possibility, a piece of skin will be removed from the area and examined under a microscope. This is called a skin biopsy. A biopsy must be done to confirm the diagnosis of basal cell carcinoma or other skin cancers.
There are many types of skin biopsies. The exact procedure depends on the location of the suspected skin cancer.
TreatmentSee also: Actinic keratosis for treatment information
Skin cancer has a high cure rate if it is treated early. Treatment depends on how big the tumor is, its location, and how far it has spread (metastasis).
- Excision refers to cutting out the tumor and using stitches to place the skin back together.
- Curettage and electrodesiccation scrapes away the cancer and uses electricity to kill any remaining cancer cells. It is used to treat cancers that are not very large or deep.
- Mohs surgery involves cutting out a layer of the skin cancer and immediately looking at it under a microscope to check if any cancer has been left behind. More layers are removed until the skin sample is free of cancer. Mohs surgery is more likely to be used for skin cancers on the nose, ears, and other areas of the face.
- Cryosurgery freezes and kills the cancer cells.
- Radiation may be used if the cancer has spread to organs or lymph nodes, or for squamous cell cancers that cannot be treated with surgery.
- Skin creams and the medications imiquimod or 5-fluorouracil may be used to treat actinic keratosis and superficial (not very deep) squamous cell carcinoma.
- Photodynamic therapy, a special type of light treatment, may be used to treat Bowen's disease (BD).
Most (95%) of squamous cell tumors can be cured if they are removed promptly. New tumors may develop, however. If you have had squamous cell cancer, have your skin regularly examined by your health care provider.
The outlook depends on a number of factors, including the type of cancer and how quickly it was diagnosed. Squamous cell carcinoma only rarely spreads to other parts of the body.
Some squamous cell skin cancers may be more difficult to treat or can spread. This risk may depend on:
- The size or shape of the cancer
- What the cancer appears like when biopsy results are examined under a microscope
- Where the skin cancer is located
- Your other health problems
- Local spread of the tumor
- Spread to other locations, including the internal organs
Call for an appointment with your health care provider if you see the sore change in:
- Appearance
- Color
- Size
- Texture
Also call if you have pain, inflammation, bleeding, or itching of an existing skin sore.
PreventionReduce your sun exposure. Protect your skin from the sun by wearing hats, long-sleeved shirts, long skirts, or pants.
Sunlight is most intense between 10 a.m. and 4 p.m., so try to limit exposure during these hours.
Use high-quality sunscreens, preferably with sun protection factor (SPF) ratings of at least 30 that protect against both UVA and UVB sunlight. Apply the sunscreen at least 30 minutes before going outside and reapply frequently. Use a sunscreen throughout the year, even during the winter. Use a waterproof formula.
Other important facts to help avoid too much sun exposure:
- Avoid surfaces that reflect light, such as water, sand, concrete, and white-painted areas.
- The dangers are greater closer to the start of summer.
- Skin burns faster at higher altitudes.
- Avoid sun lamps, tanning beds, and tanning salons.
Examine the skinregularly for any new suspicious growths or changes in an existing skin sore. A new growth that forms an ulcer or is slow to heal is suspicious.
Suspicious changes in an existing growth include:
- A change in color, size, texture, or appearance
- Development of pain, inflammation, bleeding, or itching

I'll start by breaking down the terminology. Carcinoma is a cancer derived from epithelial cells, which are the lining cells that make up the skin, lining of the gastrointestinal tract, lining of the respiratory tract, etc. Squamous cell is a particular type of epithelial cell that is flat; there are only certain places in the body that have this type of epithelial cell. Well differentiated means the cells, while cancerous, are still typical in shape, size and intracellular characteristics for the type of cell they developed from.
Putting everything back together, this is a cancer derived from the cells of either the skin or a body cavity lining that is still fairly normal appearing. Interpreting this, I would guess the cancer is associated with the skin and that the cancer is not likely to have metastasized yet.

A squamous intraepithelial lesion is an abnormal growth of squamous cells on the surface of the skin or lining of a body cavity. It can be a precancerous condition that may require further evaluation and treatment to prevent progression to cancer. Types of squamous intraepithelial lesions include squamous cell carcinoma in situ and squamous dysplasia.

No, squamous cell carcinoma is a type of cancer that arises from squamous cells in the skin or lining of organs, while squamous proliferation with verrucous features refers to an overgrowth of squamous cells in a verrucous or wart-like pattern without evidence of cancer. While they both involve squamous cells, they are distinct entities with different implications for diagnosis and management.

The word squamous refers to the shape of the cell - it means scale shaped and refers to cells that bulge in the middle and taper at the ends. There are many types of cells that are squamous cells. As such, there is no particular protein that is characteristic of squamous cells. They will possess the same set of thousands of basic housekeeping proteins that any cell will possess and supplemented with the dozens or hundreds of proteins that make them a particular kind of squamous cell.
