Intraepidermal carcinoma refers to a type of skin cancer that starts in the top layer of the skin, known as the epidermis. It is also known as squamous cell carcinoma in situ and is considered a precancerous condition as it has not yet invaded deeper layers of the skin or spread to other parts of the body.
So let us take a deeper look
Intraepidermal carcinoma, also known as squamous cell carcinoma in situ, is a type of skin cancer that originates in the top layer of the skin, called the epidermis. It is considered a precancerous condition as it has not yet invaded deeper layers of the skin or spread to other parts of the body. To provide more in-depth information, let’s dive deeper into this topic.
Intraepidermal carcinoma arises from abnormal growth and replication of squamous cells in the epidermis. These cells are responsible for forming the protective outer layer of the skin. Unlike invasive squamous cell carcinoma, which penetrates deeper layers of the skin and can metastasize, intraepidermal carcinoma is confined to the uppermost layer.
Interestingly, intraepidermal carcinoma is often detected as a result of routine screenings or during the examination of another skin condition. It typically appears as a red, scaly patch or plaque on the skin, which may become thicker and more elevated over time if left untreated. While it is considered precancerous, if not managed promptly, it can progress to invasive squamous cell carcinoma.
Now, let’s gain further insights into this topic by sharing a quote related to skin cancer:

Facts about intraepidermal carcinoma:
- Intraepidermal carcinoma is predominantly caused by excessive and cumulative exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds.
- It most commonly affects older individuals, typically over the age of 60, although it can occur in younger individuals as well.
- Fair-skinned individuals are more prone to developing intraepidermal carcinoma, as they have less melanin, a pigment that provides some natural protection against UV radiation.
- Intraepidermal carcinoma often develops on sun-exposed areas, such as the face, scalp, ears, neck, hands, and forearms.
- Risk factors for developing intraepidermal carcinoma include a history of extensive sun exposure, a weakened immune system, prolonged exposure to arsenic, human papillomavirus (HPV) infection, and a previous history of non-melanoma skin cancer.
To present the information in a visually appealing way, here’s a table listing the key characteristics of intraepidermal carcinoma:
| Intraepidermal Carcinoma |
|---|
| Originates in the top layer of the skin (epidermis) |
| Also known as squamous cell carcinoma in situ |
| Considered a precancerous condition |
| Limited to the epidermis and has not invaded deeper layers |
| Detected through routine screenings or during examination of another skin condition |
| Appears as red, scaly patches or plaques on the skin |
| Can progress to invasive squamous cell carcinoma if left untreated |
| Mainly caused by excessive UV radiation exposure |
| Commonly affects older individuals, particularly those over 60 |
| More prevalent in fair-skinned individuals |
| Often develops on sun-exposed areas |
| Risk factors include extensive sun exposure, weakened immune system, HPV infection, etc. |
Remember, early detection and prompt treatment are crucial in managing intraepidermal carcinoma, as it can help prevent its progression to more invasive forms of cancer. Regular check-ups with a dermatologist and sun protection measures can significantly reduce the risk of developing this condition.

Dr. Iris Zalaudek discusses the progression of actinic keratosis to squamous cell carcinoma, highlighting the red starburst pattern associated with this progression. She also discusses the patterns of intradermal carcinoma arising from actinic keratosis, including the presence of neovascularization, small vessels, ulceration, and the specific variant called Bowens disease. Key features of intradermal carcinoma include dotted or glomerular coiled vessels arranged in a red starburst pattern, yellowish scales, or erosions.

“Intraepidermal” means that the cancerous cells are located in the epidermis from where they originally developed (in situ). Squamous cell carcinoma in situ (SCCIS) is a vitiated, superficial growth of cancerous cells on the skin’s outer layer.
