A novel navel presenting as an umbilical polyp and urachal sinus associated with an epigastric cleft: a clue to anterior midline fusion defects.

Umbilical and periumbilical disorders may present with a diverse group of anomalies and reflect the developmental embryological events they result from. A rare occurrence in a newborn of an umbilicus with an umbilical polyp together with an urachal sinus associated with a supraumbilical abnormal skin area known as epigastric cleft is reported herein, to help to elucidate embryological steps of anterior midline fusion defects and urachal remnants.
