Age distribution depends on the type of Kaposi sarcoma.

In the United States and Europe, traditional Kaposi sarcoma has a peak incidence between 40-70 years, with a wide range of up to 89 years.

Young men with KS-AIDS who are homosexual also show a wide age range but tend to be much younger, averaging 20-40 years at age of onset.

For endemic Kaposi sarcoma in Uganda, the incidence in boys and girls was approximately the same in childhood (birth to 14 y), with a small peak in girls younger than 5 years and boys aged 5-9 years. Subsequently, a progressive rise in incidence peaked in women aged 25-29 years and in men aged 35-39 years.
