One hundred ten congenital and neonatal tumors encompassing a 25-year period are described and compared with similar published cases. Forty percent are classified as histologically malignant, and 65% of neonates with malignancies died. The types, frequency, and clinical features of neoplasms encountered in the perinatal period are markedly different from those observed in older children and adolescents. Their biological behavior and response to therapy are also dissimilar. Leukemia was responsible for the largest number of deaths followed by neuroblastoma and brain tumors.
