ABSTRACT
Tumors of the umbilical cord are rare anomalies and should be considered when using prenatal ultrasound for detection of cystic lesions. Differential diagnosis of umbilical cord tumors should comprise umbilical cord teratoma, hemangioma and angiomyxoma. It can also be an umbilical cord polyp, umbilical cord cyst, hernia into the cord and omphalocele, which are mostly isolated findings, except omphalocele. Angiomyxoma is a rare tumor of the umbilical cord and is associated with incresaed perinatal morbidity and mortality. We present a 22-year-old woman with a large umbilical cord tumor who underwent a caesarean section. As in our case, neither chromosomal aberrations nor elevated alphafetoprotein were found after amniocentesis or chordocentesis. Macroscopical and microscopical pathological examinations of the mass after delivery revealed an angiomyxoma with cystic degenerations in myxoid stroma.
