• Lymph nodes may be enlarged. A biopsy is needed to distinguish KS in nodes from other causes of lymph
node enlargement.
• Mucous membranes are often involved. In the oral cavity, the hard and soft palates are most frequently
affected.
• The membrane covering the eye (conjunctiva) may be involved, or lesions may be seen beneath the white of the
eye (sclera).
• Involvement of internal organs may be suspected by physical examination, but cannot be proven without
further testing. The physician will look for enlargement of the liver or spleen and feel for abnormal masses.
Blood and Other Tests
• Only the form of KS associated with HIV has abnormal blood tests associated with it. None of the tests,
however—including HIV, P-24 antigen or beta-2 microglobulin—is predictive, meaning they do not indicate
that KS is about to occur, its rate of growth or the chances of its responding to treatment.
• Useful information can be obtained from the total lymphocyte count and the "helper/suppressor" ratio.
Imaging
• KS may appear on a chest x-ray but cannot be distinguished from infections or other tumors. A direct view of
the lung (bronchoscopy) may be needed.
