A 6-h-old girl was transferred to the Pediatric Surgery Department of Sisli Children's Hospital due to a giant umbilical cord. Radiologic and laboratory studies were within normal limits. The umbilical mass was excised through an intraumbilical incision and the umbilicus reconstructed. Pathologic investigation demonstrated an umbilical cord hemangioma located near the umbilical end, compressing the cord structures externally. The remaining cord consisted of loose, edematous stroma similar to Wharton's jelly. The patient was discharged from the hospital on the 5th postoperative day and remains healthy 1 year later. Umbilical cord hemangioma should be considered in the etiology of a giant umbilical cord.
