What Is Cutaneoussquamous Cell Carcinoma

How Dangerous is Squamous Cell Carcinoma?

Cutaneous squamous cell carcinoma is a common type of keratinocytecancer, or non-melanomaskin cancer. It is derived from cells within the epidermis that make keratin the horny protein that makes up skin, hair and nails.

Cutaneous SCC is an invasive disease, referring to cancer cells that have grown beyond the epidermis. SCC can sometimes metastasise and may prove fatal.

Intraepidermal carcinoma and mucosal SCC are considered elsewhere.

How Fast Does Squamous Cell Carcinoma Spread

Squamous cell carcinoma rarely metastasizes , and when spreading does occur, it typically happens slowly. Indeed, most squamous cell carcinoma cases are diagnosed before the cancer has progressed beyond the upper layer of skin. There are various types of squamous cell carcinoma and some tend to spread more quickly than others.

Squamous Cell Carcinoma Screening

Diagnosis and management of Squamous Cell Carcinoma is best performed via a Full Body Scan. In the first incidence, this process includes

  • Digitally Mapping a patients entire body for any suspicious skin damage or lesion
  • Followed by a detailed Dermoscopic Examination by a trained skin cancer Specialist
  • Recording and combining all images and skin metrics into the patient record

Our expert Doctors at Bondi Junction Skin Cancer Clinic will then clearly identify and diagnose any skin cancers. Having a digital molemap or a baseline of all your skins sun damage for all family members with

  • any suspicious sun damage,
  • those with a large number of moles, or
  • have been diagnosed with melanoma is recommended.

Any changes can be more easily spotted and understood.

What Are The Clinical Features Of Cutaneous Squamous Cell Carcinoma

Cutaneous SCCs present as enlarging scaly or crusted lumps. They usually arise within pre-existing actinic keratosis or intraepidermal carcinoma.

  • They grow over weeks to months
  • They may ulcerate
  • They are often tender or painful
  • Located on sun-exposed sites, particularly the face, lips, ears, hands, forearms and lower legs
  • Size varies from a few millimetres to several centimetres in diameter.

What Are The Risk Factors For Squamous Cell Carcinoma

How to check your skin for skin cancer

Squamous cell carcinoma is mainly caused by cumulative ultraviolet exposure from the sun, according to Dr. Leffell.

Daily year-round exposure to the suns UV light and intense exposure in the summer months add to the damage that causes this type of cancer, he says. People at the highest risk for squamous cell carcinoma tend to have light or fair-colored skin blue, green or gray eyes a history of sun exposure and a tendency to sunburn quickly. Squamous cell carcinoma occurs four times more frequently in men than in women.

Although squamous cell carcinoma can be more aggressive than basal cell cancer, the risk of this type of cancer spreading is lowas long as the cancer is treated early, Dr. Leffell says. He notes that the lesions must be treated with respect because they may grow rapidly and invade deeply. While it is more difficult to treat squamous cell carcinoma that has metastasized, up to half of cases can be cured.

In a small percentage of cases, squamous cell carcinoma can grow along the tiny nerves in the skin. In this very serious condition, the squamous cell carcinoma of the face or scalp can travel along the nerves and spread to the brain.

Squamous Cell Carcinoma Prevention

Anyone who has had one Squamous Cell Carcinoma has an increased chance of developing another, especially in the same skin area or nearby. That is usually because the skin has already suffered irreversible sun damage.

Thus, it is crucial to pay particular attention to any previously treated site, and any changes noted should be shown immediately to your Doctor at the Bondi Junction Skin Cancer Clinic.

Squamous Cell Carcinomas on the nose, ears, and lips are especially prone to recurrence.

Even if no suspicious signs are noticed, regularly scheduled follow-up visits including total-body skin exams are an essential part of post-treatment care every 6 months.

To prevent Squamous Cell Carcinoma make sure you follow the recommendations below:

Basal Cell Carcinoma Stages

There are certain features that are considered to make the cancer at higher risk for spreading or recurrence, and these may also be used to stage basal cell carcinomas. These include:

  • Greater than 2 mm in thickness
  • Invasion into the lower dermis or subcutis layers of the skin
  • Invasion into the tiny nerves in the skin
  • Location on the ear or on a hair-bearing lip

After the TNM components and risk factors have been established, the cancer is given a stage. For basal cell carcinoma staging, the factors are grouped and labeled 0 to 4. The characteristics and stages of basal cell carcinoma are:

Stage 0: Also called carcinoma in situ, cancer discovered in this stage is only present in the epidermis and has not spread deeper to the dermis.

Stage 1 basal cell carcinoma: The cancer is less than 2 centimeters, about 4/5 of an inch across, has not spread to nearby lymph nodes or organs, and has one or fewer high-risk features.

Stage 2 basal cell carcinoma: The cancer is larger than 2 centimeters across, and has not spread to nearby organs or lymph nodes, or a tumor of any size with 2 or more high-risk features.

Stage 3 basal cell carcinoma: The cancer has spread into facial bones or 1 nearby lymph node, but not to other organs.

Stage 4 basal cell carcinoma: The cancer can be any size and has spread to 1 or more lymph nodes which are larger than 3 cm and may have spread to bones or other organs in the body.

Squamous Cell Carcinoma Treatment

Can Basal Cell Carcinoma Spread?

Squamous cell carcinoma can usually be treated with minor surgery that can be done in a doctors office or hospital clinic. Depending on the size and location of the SCC, your doctor may choose different techniques to remove it.

For small skin cancers:

  • Curettage and electrodessication : removing the top layer of the skin cancer then using an electronic needle to kill cancer cells
  • Laser therapy: an intense light destroys the growth
  • : a photosensitizing solution applied to your skin then activated with a light or daylight, or sometimes with intense pulsed light
  • Cryosurgery: freezing of the spot using liquid nitrogen

For larger skin cancers:

  • Excision: cutting out the cancer spot and some healthy skin around it, then stitching up the wound
  • Mohs surgery: excision and then inspecting the excised skin using a microscope this requires stitching up the wound

How Is Squamous Cell Carcinoma Of The Skin Treated When It Spreads

When this cancer spreads beyond the skin, it travels to the lymph nodes or other organs. Once it spreads, a patient has advanced cancer.

If youve been diagnosed with advanced SCC, you will be cared for by a team of medical professionals. This team will include oncologists . Your treatment plan may include one or more of the following:

Surgery: When surgery can remove the cancer and youre healthy enough to have surgery, this is often the preferred treatment. After surgery, another treatment, such as radiation therapy or chemotherapy, is often given. Adding another treatment helps to kill cancer cells.

Radiation therapy: Radiation can target cancer cells in the skin, lymph nodes, or other areas of the body. When a patient has advanced SCC, radiation therapy is often used along with another treatment.

Immunotherapy: This type of treatment helps strengthen your immune system so that it can fight the cancer. Drugs called immunotherapy medications are given for this purpose.

The U.S. Food and Drug Administration has approved one immunotherapy medication for the treatment of advanced SCC of the skin. Its called cemiplimab-rwlc.

In the clinical trials that led the FDA to approve cemiplimab-rwlc, about half the patients who had advanced SCC of the skin had their tumors shrink. In many patients who had tumor shrinkage, the shrinking lasted 6 months or longer. A few patients had their tumors disappear completely.


Pembrolizumab is also given by IV infusion.

What Makes Yale Medicines Approach To Squamous Cell Carcinoma Unique

Simple, small cancers can often be treated very well by a local dermatologist, according to Dr. Leffell. We rarely see the small cancers. We get referred to the cases that need special attention.

Dr. Leffell emphasizes that at Yale Medicine, the patient always comes first. We like to have a discussion with the patient about what happens after the skin cancer is removed, he says. We talk about what’s involved with plastic surgery and what’s involved with letting the area heal naturally. We prefer to take a minimalist approach and let the patient decide what they want us to do and how they want to let their skin heal.

If the decision is made to repair the wound using plastic surgery, we do that immediately in the office setting, Dr. Leffell says. Alternatively, allowing the wound to heal naturally is often a great option, and does not rule out doing plastic surgery down the road if needed, though that is very rarely the case.

Is There A Cure For Squamous Cell Carcinoma

Most squamous cell skin cancers are found and treated at an early stage, when they can be removed or destroyed with local treatment methods. Small squamous cell cancers can usually be cured with these treatments.

Many doctors will order a PET or CT scan once a squamous cell carcinoma diagnosis has been reached to ensure the cancer has not spread to other parts of the body and is contained within the layers of the skin. Your doctor may also test your lymph nodes near the tumor site.

Evaluation By The General Practitioner

Squamous Cell Carcinoma

Hayes Martin stated that an adult patient who presents with a palpable lateral neck mass, whether solid or cystic, should be considered to have a metastatic lymph node until proven otherwise .

In the typical patient with NCUP, the lymph nodes, located in the upper part of the neck, are clearly abnormal in size, shape or consistency. The palpable mass may be firm or, if cystic, may have a tense or soft consistency. On careful questioning, the patient may have symptoms referable to a head and neck primary tumor, such as a sore throat when swallowing, ear pain, new nasal obstruction, voice change, etc. They also may have a history of tobacco and alcohol abuse or 10 or more lifetime sexual partners. The absence of suspicious history or symptoms does not, however, rule out cancer.

If a patient has a clinical presentation and imaging typical of lymphoma, with widespread adenopathy, sometimes exhibiting splenic, liver, bone marrow or lung involvement, and sometimes with type B constitutional symptoms , this represents an appropriate clinical scenario for open cervical lymph node biopsy . If not, it would be preferable to presume carcinoma initially and avoid open or even core biopsy as an initial test.

Ultrasound-guided FNA of the neck mass for cytology is also appropriate prior to referral, but core needle biopsy should be deferred until after evaluation by the specialist and complete head and neck physical examination including fiberoptic nasopharyngo-laryngoscopy .

What Is Squamous Cell Lung Carcinoma

Squamous cell carcinoma is a type of NSCLC, which itself makes up around 84 percent of all lung cancer cases. Other types of NSCLC include adenocarcinomas and large cell carcinomas.

The main difference between each subtype of NSCLC is the lung cells that are cancerous. In squamous cell carcinomas, cancer forms in squamous cells, which are flat, thin cells that look similar to fish scales when viewed under a microscope. Squamous cell tumors tend to form in the central part of the lung or in one of the bronchi . They tend to be centrally located on X-rays.

Squamous cell carcinomas are strongly associated with cigarette smoking. Other risk factorsinclude:

  • Exposure to secondhand smoke, radon, asbestos, diesel, and mineral dust
  • Older age
  • Family history

Squamous Cell Carcinoma – Mayo Clinic

If a primary site is not identified on clinical examination, the next step will be FNA of the neck mass for cytological examination, preferably under ultrasound guidance . For patients with solid masses that harbor squamous cell carcinoma, FNA will be positive in 80% or more and repeated FNA can yield an additional increment. With cystic neck masses the percentage is lower, but still, if ultrasound assisted and directed toward the most solid parts of the lesion, in the majority of patients with a suspicious neck mass, the FNA will correctly diagnose malignancy if present.

In those cases which are not squamous cell carcinomas, and in particular when a primary below the clavicles is suspected, sophisticated diagnostic approaches, including immunocytochemistry or immunohistochemistry and molecular techniques are available to help direct a search for a primary site, based on the biopsy, and this is covered in more detail later.

The possibility of applying additional cytopathological and molecular techniques to the cytologic aspirate, to provide an estimate regarding the risk of malignancy relative to a benign branchial cleft cyst, is an area that is open for further study. If a few non-diagnostic cells are encountered, IHC or in-situ hybridization Epstein Barr Virus , P53 mutations , cytokeratin and other markers can be performed, depending on the viral prevalence in the region and level of suspicion.

How Is Metastatic Squamous Cell Carcinoma Treated

Each patients ideal course of metastatic squamous cell carcinoma treatment will vary according to the location of the primary cancer, how far it has spread, the overall health of the patient and several other factors. Many treatment plans include a combination of surgery to remove skin lesions and affected lymph nodes, as well as chemotherapy and radiation therapy to help shrink or destroy cancer cells that have traveled to other parts of the body.

Moffitt Cancer Centers Cutaneous Oncology Program offers a full spectrum of diagnostics and leading-edge treatment options to patients with squamous cell carcinoma of any stage. To speak with a Moffitt oncologist specializing in skin cancer, submit a new patient registration form online or call .


General Prognosis After Treatment

An individuals prognosis depends on the type and stage of cancer, as well as their age and general health at the time of diagnosis. The majority of Squamous Cell Carcinoma cancers are successfully treated.

When small Squamous Cell Carcinomas are removed, the scars are usually cosmetically quite acceptable. If the tumours are very large, a skin graft or flap may be used to repair the wound in order to achieve the best cosmetic result and facilitate healing.

How Serious Is My Cancer

If you have skin cancer, the doctor will want to find out how far it has spread. This is called staging.

Basal and squamous cell skin cancers don’t spread as often as some other types of cancer, so the exact stage might not be too important. Still, your doctor might want to find out the stage of your cancer to help decide what type of treatment is best for you.

The stage describes the growth or spread of the cancer through the skin. It also tells if the cancer has spread to other parts of your body that are close by or farther away.

Your cancer can be stage 0, 1, 2, 3, or 4. The lower the number, the less the cancer has spread. A higher number, like stage 4, means a more serious cancer that has spread beyond the skin. Be sure to ask the doctor about the cancer stage and what it means for you.

Other things can also help you and your doctor decide how to treat your cancer, such as:

  • Where the cancer is on your body
  • How fast the cancer has been growing
  • If the cancer is causing symptoms, such as being painful or itchy
  • If the cancer is in a place that was already treated with radiation
  • If you have a weakened immune system

Skin Cancer: Causes, Symptoms, Treatment, and Prevention

Thats because individuals who were diagnosed and treated for a squamous cell skin lesion have an increased risk of developing a second lesion in the same location or a nearby skin area. Most recurrent lesions develop within two years after the completion of treatment to remove or destroy the initial cancer.
