Umbilical granulomas commonly occur in the neonatal period. In normal circumstances, the umbilical stump falls off when the umbilical fibromuscular ring closes, 1 – 2 weeks after birth. Partial epithelialization over the stump may result in an overgrowth of granulation tissue. Thought to be due to a subclinical infection, the granuloma may range in size from 1 – 10 mm in diameter. Due to a propensity to infection potentially leading to omphalitis and necrotizing fasciitis, an umbilical granuloma should be treated.
Silver nitrate is often advocated as the first-line treatment for umbilical granulomas. However, along with its antiseptic effect, it is caustic and could damage healthy tissue adjacent to the umbilicus. A systematic review demonstrated that salt treatment was effective in most of 10 studies with no adverse effects.1
Topical application of common salt for umbilical granulomas is simple, effective and inexpensive.2,3
