Kaposi’s Sarcoma is a type of tumor of the skin that is caused by a virus referred to as “Human herpesvirus 8“. This virus is also referred to as Kaposi’s sarcoma-associated virus.
Kaposi’s Sarcoma is a cancer that arises from lymphatic endothelium rather than a true sarcoma. The first appearance is very similar to a bruise or several bruises.
It has been identified in patients and was initially categorized in 1872. The virus was identified in 1994. It is also seen and is well known in HIV Patients.
Transmission of the virus occurs by contact and sexual activity.
