An angiomyxoma involving the whole length of the umbilical cord. Prenatal diagnosis by ultrasonography.

The discovery of an umbilical cord angiomyxoma or hemangioma is a rare event. Heifetz and Rueda-pedraya have found 19 pathologic descriptions of this tumor published in the world literature since the beginning of this century.1 Improvement and wide use of ultrasound techniques in antenatal care have made the prenatal diagnosis of this lesion possible.2 This report describes an unusually extended angiomyxoma with progressive shortening of the umbilical cord associated with raised maternal serum alpha-fetoprotein and superficial angiomas of the infant's skin. The lesion was followed by ultrasound from 20 weeks gestation until delivery.
