OverviewKaposi's sarcoma was once a rare malignancy of the blood vessels but is now associated with AIDS. It is more frequently associated with AIDS in homosexual men than AIDS in IV drug users. Recent research has suggested that this malignancy may be caused by a newly discovered herpes virus. The malignancy results in purplish, grape-like lesions in the skin, gastrointestinal tract, and other organs.
