Abstract

Tumors of umbilical cord, especially angiomyxoma, are extremely rare lesions. To our knowledge, five cases of angiomyxoma have been reported previously in the umbilical cord. Sonography two weeks after the finding of an elevated serum alpha-fetoprotein, detected a mass of the umbilical cord in a 27-year-old multiparous woman at 18(+3) weeks gestation. Previous sonogram was normal (11 weeks gestational age). At 26 weeks, a premature female infant was delivered by induction and a mass was located in the region of placental insertion of the cord. Section through the mass revealed rubbery myxoid appearance. Microcopically, numerous small vascular channels with thin walls were embedded in loose myxoid matrix. A case of angiomyxoma of umbilical cord with elevation of serum alpha-fetoprotein is presented together with a review of the literature. We hope that this case will help define the natural history of primary angiomyxoma of umbilical cord.
