Kaposi's sarcoma
Kaposi's sarcoma is a rare cancer that causes slightly raised spots on the skin that range in color from purple to brown.
It remained a very rare tumor until it started showing up in patients with acquired immunodeficiency syndrome
(AIDS). The cause of Kaposi's sarcoma in AIDS patients appears to be infection with a separate virus in the herpes family.
