Diagnosis
Umbilical granuloma can be diagnosed from physical examination. If there is a discharge around the navel and the granulation tissue is large enough to be visible with the open eye, umbilical granuloma is the first to be suspected. Open eye inspection and/or dermoscopy is commonly used to recognize the granular tissue at the site. If the granuloma is not visible with the open eye, gentle pressure on the surrounding site or a surgical tweezer can be used to expose the small granuloma hidden within the umbilical pit. An otoscope may also be used by physicians in order to expose a small, sessile granuloma. Other additional tests are usually not required, but if continued, ultrasonography (US) can be used for initial diagnosis of umbilical lesions. Treatment
Topical
Although there is no singular method of treatment for umbilical granulomas, some treatment options available include common salt, silver nitrate, corticosteroids, and cleaning with alcohol. Home care following treatments include gentle cleaning the navel area with soap and sterile water, followed by open exposure of the belly button to air. Silver nitrate
Silver nitrate is the most common treatment and practiced worldwide. Neonatology textbooks suggest silver nitrate as a first-line treatment option. The application of silver nitrate to granulomas was first noted in early 1800s as a cauterizing agent.Silver nitrate can be used as an antiseptic, an astringent, and as a caustic agent, depending on the indication. Its application requires medical personnel for treatment and may have unfavorable adverse effects if applied improperly.
