Juvenile Classic Kaposi's Sarcoma: a Report of Two Cases, One with Family History

Two cases of juvenile classic Kaposi's sarcoma (KS), one with family history, are described, and the natural history of KS is briefly reviewed. Case 1a was a child whose disease ran an aggressive course and did not respond to therapy. Case 1b was the mother of the child: She had a relapsed localized form that was treated by surgery and chemotherapy, and she has been disease free since 1990. The second juvenile case was a 4-year-old boy with a localized form that relapsed but was successfully treated by surgery, chemotherapy, and radiation therapy. He has been free of disease since 1986. Family history in juvenile KS has not previously been reported unrelated to acquired immunodeficiency syndrome in a Western country.
