Kaposi's Sarcoma, Unspecified: What You Need to Know

Kaposi's sarcoma (KS) is a type of cancer that affects the cells that line the lymph or blood vessels. KS can appear as red, purple, or brown lesions on the skin, mucous membranes, or internal organs. Unspecified KS refers to a subtype that does not fit into any of the other categories.

While KS can affect anyone, it is most commonly seen in people with weakened immune systems, such as those with HIV/AIDS. However, it can also occur in people who have had organ transplants or are taking immunosuppressive drugs.

KS is caused by the human herpesvirus 8 (HHV-8), also known as Kaposi's sarcoma-associated herpesvirus (KSHV). The virus is transmitted through sexual contact, blood transfusions, or organ transplants. However, not everyone who is infected with HHV-8 will develop KS.

Signs and Symptoms

KS can affect different parts of the body and can present with different symptoms. The most common symptom is the appearance of skin lesions that are red, purple, or brown in color. These lesions may be flat or raised and can be painless or itchy. KS can also affect the internal organs, such as the lungs, liver, and digestive system, and can cause symptoms such as difficulty breathing, abdominal pain, and vomiting.

Treatment Options

The treatment for KS depends on the extent and location of the lesions as well as the person's overall health. If the lesions are small and localized, they may be removed surgically or treated with radiation therapy. If the lesions are more widespread, chemotherapy may be necessary. In people with HIV/AIDS, treatment for the virus itself is also important.


There is no surefire way to prevent KS, but there are some steps you can take to reduce your risk of contracting HHV-8. These include practicing safe sex, not sharing needles, and avoiding blood transfusions and organ transplants from high-risk donors.

  1. Practice safe sex.
  2. Avoid sharing needles.
  3. Avoid blood transfusions and organ transplants from high-risk donors.
