PATHOLOGY

Detailed explanation-1: -People infected with human immunodeficiency virus (HIV)-the virus that causes AIDS-have the highest risk of Kaposi’s sarcoma. The immune system damage caused by HIV allows cells harboring HHV-8 to multiply. Through unknown mechanisms, the characteristic lesions form.

Detailed explanation-2: -Kaposi’s sarcoma is caused by a virus called the human herpesvirus 8 (HHV-8), also known as the Kaposi’s sarcoma-associated herpesvirus (KSHV). This virus is thought to be spread during sex, through saliva, or from a mother to her baby during birth.

Detailed explanation-3: -Kaposi sarcoma is a disease in which cancer cells are found in the skin or mucous membranes that line the gastrointestinal (GI) tract, from mouth to anus, including the stomach and intestines. These tumors appear as purple patches or nodules on the skin and/or mucous membranes and can spread to lymph nodes and lungs.
