Hemangioma of the umbilical cord with pseudocyst.

A case of umbilical cord hemangioma with a large cystic mass, diagnosed by ultrasound at 18 weeks of gestation, is reported. A normal female infant was born at 39 weeks of gestation. The umbilical cord was 32 cm long with a cystic mass (10 × 10 × 8 cm). Histopathologic examination of the umbilical cord revealed a hemangioma with myxomatous degeneration, presenting as a large cyst with thinning of the umbilical venous wall. A total of 33 umbilical cord hemangioma cases have been reported in detail, and only seven cases had a pseudocystic degeneration. The associated pathologic findings of umbilical cord hemangioma are reviewed.
