What Types Of Skin Are Particularly Prone To Squamous Cell Carcinoma In Horses?

Horses with lightly pigmented skin, such as those with a gray hair coat or white faces, are especially prone to developing SCC, and some breeds, such as Clydesdales, may have a genetic predisposition.

What causes squamous cell carcinoma in horses?

Carcinoma is caused by exposure to carcinogens (cancer inducing agents) such as sunburn or smegma (in the case of penile or clitoral forms). There is greater risk in parts of the world where the sun is stronger (nearer the equator).

Which is the considered highest risk site in squamous cell carcinoma?

The sun-exposed head and neck are the most frequent sites for these cancers to arise and in most patients diagnosed with a cutaneous squamous cell carcinoma, local treatment is usually curative.

What is the most common skin tumor in horses?

Sarcoids are the most common type of skin tumor in horses which can occur in horses of any age. It is most common in adult Quarter Horses and other closely related breeds but rare in Standardbreds.

What is the most common cause of squamous cell carcinoma?

The cause of most squamous cell carcinoma (SCC) of the skin is well known. People usually develop this skin cancer because ultraviolet (UV) light has badly damaged their skin. Most UV light comes from: The sun.

What is squamous cell carcinoma and where do they commonly occur?

About 2 out of 10 skin cancers are squamous cell carcinomas (also called squamous cell cancers). These cancers start in the flat cells in the upper (outer) part of the epidermis. These cancers commonly appear on sun-exposed areas of the body such as the face, ears, neck, lips, and backs of the hands.

What feeds squamous cell carcinoma?

Prior studies have shown that malignant cancer cells appear to feed on sugar as their energy source. New findings reveal that squamous cell carcinoma (SqCC) are particularly dependent on sugar consumption compared with other cancer types.

Where is the most common site for squamous cell carcinoma?

Squamous cell carcinoma of the skin most often occurs on sun-exposed skin, such as your scalp, the backs of your hands, your ears or your lips. But it can occur anywhere on your body, including inside your mouth, the bottoms of your feet and on your genitals.

Where does squamous cell carcinoma spread first?

Hanke: The first place SCCs metastasize to is the regional lymph nodes. So if you have a squamous cell carcinoma on your cheek, for example, it would metastasize to the nodes in the neck. But there are treatments for that. Patients can have surgery, radiation and, in some advanced cases, immunotherapy medication.

What is the highest risk factors for basal and squamous cell carcinoma?

Ultraviolet (UV) light exposure
Exposure to ultraviolet (UV) rays is thought to be the major risk factor for most skin cancers. Sunlight is the main source of UV rays. Tanning beds are another source of UV rays.

Is the most common type of skin tumor in horses it is locally invasive but rarely metastatic?

Equally important to cases of SCC seen at UF, yet not metastatic, are sarcoids. These are considered the most common type of skin tumor in horses and can be locally aggressive.

Are grey horses more prone to sarcoids?

There is no clear link between colour or breeds of horses being more susceptible. Sarcoids can appear singly as tiny lumps or in clusters. As they enlarge, the skin may ulcerate and become infected.

What are the most common areas of disease in the horse?

What are five risk factors for basal and squamous cell carcinoma?

These factors increase your BCC risk:

• UV exposure from the sun or indoor tanning.
• History of skin cancer, including squamous cell carcinoma (SCC) or melanoma.
• Age over 50: Most BCCs appear in people over age 50.
• Fair skin: People with fair skin have an increased risk.
• Male gender: Men are more likely to develop BCC.

What is the root of squamous cell carcinoma?

SCCs arise from epithelial tissues that can be classified as stratified squamous epithelium (which includes epithelia of skin, oesophagus and oral cavity) and non-squamous epithelia (which include airway epithelium).

What are the most common subtypes of a squamous cell carcinoma?

The primary types of squamous cell carcinoma are:

• Adenoid/pseudoglandular squamous cell carcinoma.
• Intraepidermal squamous cell carcinoma.
• Large cell keratinizing squamous cell carcinoma.
• Large cell non-keratinizing squamous cell carcinoma.
• Lymphoepithelial carcinoma.
• Papillary squamous cell carcinoma.

Where do carcinomas most often appear?

Basal cell carcinoma usually develops on sun-exposed parts of your body, especially your head and neck. Less often, basal cell carcinoma can develop on parts of your body usually protected from the sun, such as the genitals.

Where are carcinomas most found?

Carcinoma is the most common type of cancer. It begins in the epithelial tissue of the skin, or in the tissue that lines internal organs, such as the liver or kidneys. Carcinomas may spread to other parts of the body, or be confined to the primary location.

What organs does squamous cell carcinoma affect?

If left untreated, squamous cell carcinoma can spread to nearby lymph nodes, bones or distant organs (such as the lungs or liver). Normal squamous tissue usually appears flat. When this tissue develops cancer it can appear as round masses that are can be flat, raised, or ulcerated.

How can you reduce the risk of squamous cell carcinoma?

Preventing Squamous Cell Carcinoma of the Skin

• Checking your skin once a month.
• Seeing a dermatologist annually.
• Using sunscreen. To be effective, sunscreens should be broad spectrum, at least SPF 30 and waterproof.
• Avoid tanning beds.
• Wearing protective clothing.

What prevents squamous cell carcinoma?

You can lower your risk for squamous cell carcinoma and other skin cancers by regularly using sunscreen and minimizing exposure to ultraviolet radiation from the sun, sunlamps and tanning beds.
