Kaposi Sarcoma, a form of skin cancer, manifests in the form of lesions or patches on the skin. These spots consist of cancer cells, blood cells, and blood vessels. The development of this skin cancer is attributed to the mutation of the human herpes virus 8 and is classified into five different types. These include:
- Classic KS: This type of Kaposi Sarcoma progresses slowly.
- African KS: Found predominantly in central Africa, this form affects people in the region.
- Immunosuppressive treatment-related KS: Arises unintentionally due to medical treatment and surgery in individuals with weakened immune systems.
- Epidemic KS: Directly linked to the HIV-AIDS virus, this type of Kaposi Sarcoma occurs during an epidemic.
- Non-epidemic gay related KS: Primarily affects homosexual males and is not linked to an epidemic.
There may be overlapping symptoms and signs among these types, with the severity depending on the number and location of the lesions.
Understanding Flat Lesions in Kaposi Sarcoma
Flat lesions are one of the initial indications of the presence of Kaposi Sarcoma, a type of cancer. These lesions have the tendency to develop rapidly, starting from just one lesion and eventually spreading to other areas. In some cases, they can merge with neighboring lesions, forming a larger cancerous skin tumor. It is important to note that any part of the body, including the mouth, nose, and throat, can be affected by these flat lesions.
Flat lesions, also known as nodular lesions, come in various colors such as brown, pink, or reddish-purple. Additionally, they may exhibit a yellow or brown pigment on the surrounding skin area adjacent to the lesion patch.
Raised Lesions in Kaposi Sarcoma
In Kaposi Sarcoma, raised lesions are referred to as infiltrating lesions. Unlike the flat, nodular lesions, these patches have a raised surface. Although they may resemble brown moles, these lesions are actually growing underneath the skin rather than on top of it. They can also be found inside the mouth and nose.
Regular skin checks are crucial, particularly if there are any suspicious-looking moles developing beneath the skin.
