Signs and Symptoms
If there are signs of Kaposi's sarcoma (KS), a doctor will examine the skin and lymph nodes carefully. Lymph nodes are small, bean-shaped structures that are found throughout the body. They produce and store infection-fighting cells. The doctor also may recommend other tests to see if the patient has other diseases.
KS causes red or purple patches, called lesions, on the skin as well as on mucous membranes. It may spread to other organs in the body, such as the lungs, liver or intestinal tract.
