Hepatic teratomas in children.

This report describes a hepatic teratoma in a newborn child. Microscopic examination showed a predominantly immature teratoma containing tissue representative of all three germ layers. No evidence of malignant tissue was found in the tumor, and no clinical evidence of metastasis was found in the child. A markedly elevated serum alpha fetoprotein was documented. A review of the literature on hepatic teratomas in children is also presented.
