Kaposi sarcoma (KS) is a cancer that affects the soft tissues such as skin, mouth (oral cavity), food pipe (esophagus), and anal canal. Generally individuals with low immunity or those who are immunosuppressed are more at risk for KS.
"Classic" KS that was found among older men of Jewish heritage is now rare. In this form, it is slow to grow but in AIDS individuals it progresses rapidly.
Kaposi sarcoma-associated herpes virus (KSHV) causes KS in immunocompromised individuals. Men are much more prone to develop KS than women and it affects them in the age group between the ages of 25 and 59.
Though Kaposiís sarcoma was a common cancer in AIDS, the number of cases has come down during the past few years. The incidence of KS is high among African Americans and low in Asians and Pacific Islanders.Symptoms of Kaposiís Sarcoma

Some such lesions can be treated locally with cryotherapy, laser therapy, radiation or injection with anticancer drugs.
Severe and widespread cases are treated with injectable drugs.
