What characteristic symptom is associated with Kaposi Sarcoma in HIV-positive individuals?

Kaposi Sarcoma is a type of cancer that often presents with distinct lesions on the skin, particularly in individuals with HIV/AIDS. The characteristic symptom associated with Kaposi Sarcoma is the presence of purple areas on the skin, known as cutaneous lesions. These lesions can vary in size and may appear as flat spots, nodules, or plaques, and are commonly found on the face, legs, and feet.

These purple lesions result from the proliferation of blood vessels and inflammation, which is a direct consequence of the immunocompromised state seen in HIV-positive individuals. This type of cancer is classified as an AIDS-defining illness, meaning that its development indicates an advanced stage of HIV infection.

While the other symptoms listed may arise due to various other conditions or complications associated with HIV, they are not characteristic of Kaposi Sarcoma. Frequent nosebleeds, severe dental pain, and increased sensitivity to light do not specifically indicate the presence of this type of cancer.
