Classic KS: Multiple red or purple dermal plaques, nodules,
and tumors. Lesions occur most commonly on the lower limbs, but may also
occur on the upper limbs, trunk, head, neck, and genitalia. Edema is common
and hemorrhage of lesions may occur. Involvement of internal organs may
occur; in fact, the disease may be exclusively visceral with no cutaneous
lesions. The condition is slowly progressive, with death occurring from
generalized disease with cachexia, hemorrhages, or impairment of vital organ
function by tumor growth.
