Umbilical granuloma

Major points
• Pink papule or nodule within the umbilical stump
that bleeds easily (Figure 2.8)
• Develops at the site of the umbilical cord remnant
after it falls off
• Clinically resembles a pyogenic granuloma
Pathogenesis
• Inadequate healing at umbilical stump with
subsequent endothelial cell proliferation and
inflammation (granulation tissue)
• Not true granuloma
Diagnosis
• Clinical findings
• Histology: endothelial cell proliferation without
atypia
Illustrated Manual of Pediatric Dermatology 14
Differential diagnosis
• Omphalomesenteric duct cyst/umbilical polyp
• Patent urachus
Treatment
• Silver nitrate application
• Cryocautery, ligature and excision have been
reported to be successful
Prognosis
• Can resolve spontaneously but usually requires
treatment
• Persistence indicates the presence of an umbilical
remnant
