Kaposi’s Sarcoma

Kaposi’s Sarcoma is a malignant tumor that is often associated with AIDS (Acquired Immune Deficiency Syndrome). Before the AIDS epidemic, Kaposi’s sarcoma was not common and usually developed slowly in elderly Italian and Jewish men, and rarely, in elderly women.

In people with AIDS, Kaposi’s sarcoma is caused by an interaction between:

  • HIV, the virus that causes AIDS
  • A weakened immune system, and
  • A human herpes virus called HHV-8.

In people with AIDS, Kaposi’s sarcoma can develop rapidly and involve the skin, lungs, intestinal tract, and other organs. The tumors on the skin are bluish-red or purple.
