Kaposi Sarcoma is a type of skin cancer. Creating lesions, or patches on the skin, these spots are comprised of cancer cells, blood cells, and blood vessels. Classified into five different types, this skin cancer forms because of the mutation of the human herpes virus 8. The five groups are - the slowly developing Classic KS, African KS affecting people in central Africa, the unintentionally formed Immunosuppressive treatment-related KS, from medical treatment and surgery, Epidemic KS, which comes directly from the HIV-AIDS virus, and non-epidemic gay related KS affecting homosexual males. Many symptoms and signs will cross over each other, and the severity depends on how many lesions and where.
Flat skin lesions are some of the very first signs of Kaposi Sarcoma. They can develop quite quickly starting with just one, but then spread and even join with neighboring lesions to form one big cancerous skin tumor. Any part of the body can be affected, even inside the mouth, nose, and throat. The flat lesions know as nodular lesions, can range in color from brown to pink or reddish purple and they may also have a yellow or brown pigment on the skin surrounding the lesion patch.
