Carcinoma in situ of skin of trunk
Carcinoma in situ of the skin is a type of skin cancer that occurs in the outer layer of the skin. It is also known as in situ squamous cell carcinoma. The trunk is one of the most common locations for this type of cancer to develop.
This type of skin cancer is caused by prolonged exposure to UV radiation from the sun or tanning beds. It typically appears as a red, scaly patch on the skin that may bleed or become crusty. It can also appear as a raised bump or a thickened, scaly area.
Carcinoma in situ of the skin is not invasive, meaning it does not spread to other parts of the body. However, if left untreated, it can develop into invasive skin cancer, which can be life-threatening.
The treatment for carcinoma in situ of the skin typically involves surgical removal of the affected area. This can be done through several methods, including excision, curettage and electrodessication, or Mohs surgery. In some cases, topical medications may be used to treat the affected area.
- Excision: This involves cutting out the affected area of skin and some of the surrounding tissue.
- Curettage and electrodessication: This involves scraping away the affected area of skin and then using an electric current to destroy any remaining cancer cells.
- Mohs surgery: This involves removing layers of skin one at a time until all of the cancer cells have been removed.
After treatment, it is important to protect your skin from further damage by wearing protective clothing and sunscreen, avoiding tanning beds, and staying out of the sun during peak hours.
If you notice any changes in your skin, such as a new growth, a change in the appearance of an existing growth, or a sore that does not heal, it is important to see a dermatologist for evaluation. Early detection and treatment can help prevent the development of invasive skin cancer.
