Twelve cases of childhood Kaposi's sarcoma seen at the Uganda Cancer Institute over the last 7 years are reported. The disease presents mainly as generalized lymphadenopathy, with sparsely and anomalously distributed cutaneous nodules, and has a higher proportion of females with the disease than in the adult form. The histology is usually of mixed cell type. If not treated, childhood Kaposi's sarcoma runs a fulminating course, but disease control with chemotherapy is associated with prolonged survival.
