Gastric polyp of the umbilicus in an 8-year-old boy.

A case of unbilical polyp composed of gastric mucosa is reported in a 8-year-old boy. This is an extremely rare lesion probably originating in remnants of the omphalo-enteric duct and mainly diagnosed in the newborn period. Clinically, this polyp should be differentiated from exhuberant proliferation of granulation tissue which represents the granuloma pyogenicum of the umbilical scar.
