Prolapsed Umbilical Meckel's Diverticulum Mimicking Umbilical Granuloma: A Rare Differential of a Common Problem

Umbilical lesions in children represent a wide spectrum of congenital or acquired anomalies. Congenital anomalies are mainly because of failed obliteration of the omphalomesenteric duct while acquired pathologies are either because of delayed umbilical cord separation causing umbilical granuloma or result from umbilical stump infection producing omphalitis with persistent discharge. Meckel's diverticulum is considered the most common gastrointestinal congenital anomaly resulting from obliteration failure of the omphalomesenteric duct while umbilical granuloma is a common acquired umbilical lesion seen in daily practice. Prolapsed Meckel's diverticulum mimicking an umbilical granuloma is rare; we report a case where it was misdiagnosed and mistreated as an umbilical granuloma based on its appearance.
