Can Squamous Cell Carcinoma Go Away On Its Own

non keratinizing squamous cell carcinoma

They may go away on their own and come back. You should call your doctor if you notice a change in the color, texture, or appearance of your skin or if you have a sore that does not heal or bleeds. Your doctor can diagnose squamous cell carcinoma by examining the growth and performing a biopsy of the suspected area.

Factors Affecting Squamous Cell Carcinoma Prognosis

There are a handful of factors that can affect a patients prognosis, including:

  • Having a weakened immune system
  • The location of the tumortumors found on the face, scalp, fingers and toes spread more easily, as do tumors that arise in an open wound
  • If the cancer has recurred
  • Larger tumors and those that are growing deep in the skin

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.

Types Of Squamous Cell Carcinoma

There are several types of squamous cell carcinoma. Some are more likely to spread than others, but in general, most share similar characteristics. The primary difference between each subtype is histological .

To determine which type of squamous cell carcinoma a patient has, a pathologist will examine a tissue sample underneath a microscope. By identifying the type of cells that are present in a lesion, an oncologist can tailor a patients treatment plan to achieve the best possible outcome and quality of life.

The primary types of squamous cell carcinoma are:

  • Adenoid/pseudoglandular squamous cell carcinoma
  • Large cell keratinizing squamous cell carcinoma
  • Large cell non-keratinizing squamous cell carcinoma
  • Lymphoepithelial carcinoma
  • Small cell keratinizing squamous cell carcinoma
  • Spindle cell squamous cell carcinoma
  • Verrucous squamous-cell carcinoma

At Moffitt Cancer Center, we diagnose and treat a complete range of skin cancers, including the unique variants of squamous cell carcinoma. Screening, staging and long-term follow-up services are also available as part of our commitment to providing comprehensive care.

Referrals are not required to seek a diagnosis or treatment at Moffitt. If youve been diagnosed with or are concerned that you are showing signs of one of the different types of squamous cell carcinoma, call or submit a new patient registration form online.

Conservative Management Of Unusual Keratinising Squamous Metaplasia Of The Bladder In A 28

Fernando Vázquez Alonso

1Servicio de Urología, Hospital Universitario Virgen de las Nieves, Avenida de las Fuerzas Armadas, No. 2, 18014 Granada, Spain


Keratinizing squamous metaplasia of the bladder is rare and is usually associated with urinary tract infections and chronic irritation. It is considered a precancerous condition of squamous cell carcinoma, especially when more than 50% of the bladder surface is affected. Medical treatment cannot eradicate this lesion. When it is limited to a small area of the bladder, transurethral resection is possible. Annual cystoscopy with multiple biopsies as well as annual upper tract imaging is proposed in the follow up of these patients. We present a preliminary 2-year followup report of a keratinizing squamous metaplasia of the bladder in a 28-year-old female patient with no previous risk factors.

1. Introduction

Keratinizing squamous metaplasia of the bladder is a rare entity which is mostly found in males. Risk of invasive carcinoma, retractile bladder, or obstructive uropathy appears when the lesion persists over time . Treatment and subsequent follow-up management are still controversial.

2. Case Presentation

The cystoscopy revealed a whitish thin plaque clearly differentiated from the normal mucosa of the bladder trigone.
Squamous metaplasia of the bladder covered by a thick keratin layer.

What Is The Difference Between Keratinized And Nonkeratinized Epithelium

The key difference between keratinized and nonkeratinized epithelium is that keratinized epithelium is impervious to water while nonkeratinized epithelium is pervious to water. Moreover, keratinized epithelium is an effective barrier, while nonkeratinized epithelium is a less effective barrier. The surface layer of keratinized epithelium is composed of dead cells which have keratin while the surface layer of nonkeratinized epithelium is composed of living cells and keratin is absent in those cells.

The below infographic details more differences between keratinized and nonkeratinized epithelium in tabular form for side by side comparison.

Pathologic Features And Differential Diagnosis

Squamous Cell Carcinoma Treatment Options

Squamous cell carcinomas are typically large tumors that replace the thyroid extensively. The tumors may show a spectrum of appearances ranging from well differentiated to poorly differentiated. In many cases, the squamous components merge with areas of undifferentiated carcinoma accordingly, some authors placed these tumors in the undifferentiated category. Similar to undifferentiated carcinomas, small foci of well-differentiated PTC or follicular carcinoma may be found within squamous carcinomas. This finding supports the view that some squamous cell carcinomas may arise from metaplastic foci of differentiated thyroid carcinomas, particularly of the papillary type.

Primary squamous cell carcinomas of the thyroid must be distinguished from metastases of squamous cell carcinoma to the thyroid gland and from direct extension of primary squamous cell carcinomas originating from the larynx or trachea.

What Is Nasopharyngeal Cancer

Nasopharyngeal cancer is a type of head and neck cancer. It starts in the nasopharynx, the upper part of the throat behind the nose and near the base of skull. Cancer starts when cells begin to grow out of control. Cells in nearly any part of the body can become cancer, and can spread to other areas.

What Is Invasive Squamous Cell Carcinoma

Invasive squamous cell carcinoma is a type of cancer that occurs in the flat cells that make up the outer layer of skin and the linings of some organs, known as squamous cells. In this case, the word invasive means that the cancerous tumor has penetrated deeply into the skin or organ, as opposed to remaining a surface lesion. For example, in cases of invasive squamous cell carcinoma of the skin, the tumor may have penetrated into the dermis through the epidermis. Depending on the location, size, and severity of the tumor, there are several different courses of treatment that may be pursued.

Squamous cell carcinoma is the second most common type of skin cancer after basal cell carcinoma. Most often it is caused by exposure to UV rays, either through natural sunlight or by indoor tanning. People with fair skin are particularly susceptible. It can also occur in organs as diverse as the prostate, bladder, and larynx, although these are nowhere near as common as squamous cell skin cancer. Exposure to radiation or chemical carcinogens, as well as some inflammatory or scarring disorders, can also increase the risk of squamous cell cancer.

Stage 0 Squamous Cell Carcinoma

This is a very early stage that may or may not develop into SCC depending on whether it is caught in time and treated. This is considered a pre-malignant or pre-cancerous stage and is also known as carcinoma in situ or Bowens disease. It is at this point only present in the upper layer of the skin known as the epidermis and is yet to penetrate to lower layers and spread to deeper areas. Cells have begun to turn cancerous but have not yet spread and affected surrounding areas.6

The features of Non-Keratinizing Squamous Cell Carcinoma of Lung may include:

  • A majority of the tumors originate from the central airways . However, tumors may be present anywhere in the lung
  • The main bronchus or branches of the bronchus is mostly involved
  • The tumor appears as a polypoid mass with peripheral projections. It can grow to large sizes
  • The mass can invade the lung tissues and adjacent structures and result in bronchial lumen occlusion
  • Some tumors arise in the periphery and may exhibit endobronchial growth pattern, invading bronchial wall and lung tissue

Early-stage lung cancer rarely causes any signs and symptoms and initially makes for a difficult diagnosis. Besides, several of the primary symptoms may result from non-malignant disorders too. The overlapping signs and symptoms may result in a delayed diagnosis of lung cancer in some cases.

The common signs and symptoms may include the following:

  • Shortness of breath that gets worse with time difficulty in breathing
  • Cough that may be persistent blood in cough/sputum
  • Chest pain, heaviness in the chest
  • Changes to voice, hoarseness, or loss of voice

Signs and symptoms associated with Non-Keratinizing Squamous Cell Carcinoma of Lung, which may emerge during the later stages of the condition, include:

  • High temperatures and excessive night sweats
  • Sudden weight loss unintentional weight loss changes in appetite
  • The individual is easily tired, resulting in fatigue even with minimal activity
  • Headache

What Are The Similarities Between Keratinized And Nonkeratinized Epithelium

  • Keratinized and nonkeratinized epithelium are two types of epithelia based on the presence and absence of the keratin protein.
  • Both keratinized and nonkeratinized epithelium consists of stratified squamous epithelium.
  • The cells of both epithelia increase in size as they migrate from the basal to the prickle cell layer.
  • Moreover, cell shapes change in both epithelia.
  • The synthesis of tonofilaments also occurs in both epithelia.

Stage Ii Squamous Cell Carcinoma

Once the tumor grows bigger than 2 cm, it moves into the zone of stage II SCC. It has at this stage, spread into the dermis or lower, deeper layers of the skin from the epidermis. However, it is still contained within the skin and does not affect the bone, cartilage or muscle. It may, however, have two or more high-risk features.8

    What Is Metastatic Squamous Cell Carcinoma

    Metastatic squamous cell carcinoma is a form of cancer which can impact the skin, lips, pancreas, and other areas of the body, which has spread beyond the point where it originated. Some areas are more prone to metastasis than others. For instance, pancreatic squamous cell carcinoma is very aggressive, while most cancers which occur on the skin spread slowly or do not spread at all.

    The term metastatic means that the cancer has migrated from its original starting area to another part of the body. This makes it much more difficult to treat, although this depends on where and how far it has spread. Metastatic squamous cell carcinoma usually occurs in the pancreas. Other forms of squamous cell carcinoma are rare or they do not spread as often.

    One of the most common types of squamous cell carcinoma occurs on the skin. This type of cancer very rarely spreads. When it does, it can move into the blood, neck, or lungs. When caught early, this form of cancer has a high cure rate. When it occurs within internal organs, such as the pancreas, it can make early detection difficult.
