The incidence of second malignancies in subsets of Kaposi's sarcoma.

There is strong evidence linking Kaposi's sarcoma with an increased risk of developing a second primary malignancy. This risk of a second malignancy appears to depend in part on the clinical setting in which Kaposi's sarcoma develops. This paper examines these risks by relating them to specific subsets of Kaposi's sarcoma and to specific types of second malignancies.
