title: Umbilical and periumbilical dermatoses.
abstract: The umbilicus may be the site of congenital and acquired malformations and may harbor clinical clues to the diagnosis of potentially fatal inherited disorders, primary skin conditions, and a variety of infectious diseases. Both benign and malignant tumors may involve the umbilicus, and some are unique to this site. Finally, cutaneous signs localized to this anatomic location may be found in diverse systemic diseases.
