Non-infectious umbilical disorders represent a diverse group of congenital, developmental, and acquired conditions affecting the umbilical region of newborns. Although many are benign and self-limiting, accurate recognition is essential to distinguish them from omphalitis and other potentially serious neonatal conditions. This review summarizes the principal non-infectious umbilical disorders in newborns, focusing on their etiology, clinical manifestations, diagnostic approaches, and differential diagnosis. Current clinical literature concerning neonatal umbilical abnormalities was reviewed, with emphasis on congenital umbilical anomalies, umbilical granuloma, umbilical hernia, urachal remnants, and omphalomesenteric duct remnants. Clinical presentation, physical examination findings, and appropriate imaging approaches were considered. Common non-infectious disorders include umbilical granuloma, umbilical hernia, umbilical polyps, urachal anomalies, and persistent omphalomesenteric duct remnants. Clinical manifestations vary from a small moist or reddish umbilical mass to persistent umbilical discharge, reducible abdominal protrusion, bleeding, or drainage of urine or intestinal contents. Diagnosis is primarily clinical, while ultrasonography and other imaging modalities are indicated when congenital anomalies or deeper structural abnormalities are suspected. Differentiation from infectious omphalitis is essential. Early identification and appropriate differential diagnosis of non-infectious umbilical disorders can prevent unnecessary treatment and facilitate timely management of congenital abnormalities.
