An umbilical granuloma is a common condition that affects newborns and young infants. In simple terms, it refers to the formation of a small, fleshy lump in the belly button area. Although it may sound concerning, umbilical granulomas are generally harmless and can be easily treated. An umbilical granuloma is an overgrowth of tissue that develops in the belly button (umbilicus) of infants. During pregnancy, the umbilical cord connects the baby to the mother, providing essential nutrients and oxygen. After birth, the umbilical cord is clamped and cut, leaving behind the belly button. In some cases, the healing process of the belly button can be disrupted, resulting in the formation of an umbilical granuloma.

Types

Different types of umbilical granulomas and explain them in simple terms. We will also discuss effective treatment options to help parents and caregivers deal with this condition.

Umbilical Granuloma: An umbilical granuloma is a small, fleshy lump that forms in the belly button. It is typically bright red in color and may ooze a clear or yellowish fluid. Umbilical granulomas are non-dangerous and usually painless. They can be categorized into the following types:

a. Wet Umbilical Granuloma: Also known as a moist granuloma, this type is characterized by the presence of a sticky, wet discharge around the belly button. It often appears as a small, reddish lump with a damp surface. Wet umbilical granulomas are caused by excess moisture and inadequate drying of the umbilical stump.

b. Dry Umbilical Granuloma: In contrast to wet granulomas, dry umbilical granulomas do not have any discharge or moisture. They appear as a firm, dry lump in the belly button. Dry granulomas typically result from improper care or cleaning of the umbilical stump, leading to slow healing and the formation of a hardened mass.

Causes

It is usually harmless but may require medical attention.

Delayed Umbilical Cord Separation: Sometimes, the umbilical cord takes longer to separate from the baby’s belly button, leading to the development of a granuloma.
Umbilical Infection: Infections can occur in the umbilical stump after birth, leading to the formation of a granuloma.
Poor Hygiene: Insufficient cleanliness of the umbilical area can increase the risk of developing a granuloma.
Umbilical Cord Not Cut Properly: If the umbilical cord is not cut correctly during childbirth, it can result in an increased likelihood of developing a granuloma.
Moisture Retention: Excessive moisture in the umbilical area can create an environment suitable for granuloma formation.
Umbilical Trauma: Rough handling of the umbilical stump or accidental injury can trigger the development of a granuloma.
Excessive Tugging: Pulling or tugging at the umbilical stump can cause irritation and contribute to granuloma formation.
Incomplete Healing: If the umbilical stump does not heal completely after birth, it may lead to the formation of a granuloma.
Umbilical Prolapse: In rare cases, the umbilical cord may protrude through the belly button, increasing the risk of granuloma development.
Umbilical Hernia: Umbilical hernias, where abdominal tissues protrude through the belly button, can sometimes lead to granuloma formation.
Umbilical Polyp: A small, benign growth called an umbilical polyp can develop and contribute to granuloma formation.
Prolonged Umbilical Stump Inflammation: Inflammation of the umbilical stump that persists beyond the usual healing period can result in granuloma formation.
Poor Circulation: Insufficient blood flow to the umbilical area can impair healing and increase the risk of developing a granuloma.
Premature Birth: Babies born prematurely may have a higher risk of developing umbilical granulomas due to an underdeveloped umbilical area.
Excessive Umbilical Stump Moisturizing: Overuse of ointments, creams, or oils on the umbilical stump can prevent drying and contribute to granuloma formation.
Umbilical Stump Not Kept Clean and Dry: Failure to keep the umbilical stump clean and dry can impede the healing process and increase the likelihood of granuloma development.
Genetic Factors: Certain genetic predispositions may make some infants more prone to developing umbilical granulomas.
Umbilical Stump Not Protected: If the umbilical stump is exposed to friction or rubbing against clothing, it can delay healing and promote granuloma formation.
Maternal Factors: Maternal health conditions, such as diabetes or obesity, can indirectly contribute to umbilical granuloma development in infants.
Umbilical Stump Contamination: If the umbilical stump comes into contact with contaminated objects or surfaces, it can increase the risk of developing a granuloma.
Umbilical Stump Abnormalities: Structural abnormalities or irregularities in the umbilical stump can hinder proper healing and lead to granuloma formation.
Inadequate Umbilical Stump Care: Improper cleaning or care of the umbilical stump can disrupt the healing process and promote granuloma formation.
Umbilical Stump Not Clamped Correctly: If the umbilical stump is not clamped properly after birth, it can impede healing and contribute to granuloma development.
Umbilical Stump Tied Too Tightly: Tying the umbilical stump too tightly can restrict blood flow and hinder healing, increasing the likelihood of granuloma formation.
Allergic Reactions: In some cases, an allergic reaction to certain substances, such as soaps or lotions, applied to the umbilical area can trigger granuloma formation.
Umbilical Stump Not Kept Elevated: Failure to keep the umbilical stump elevated and exposed to air can impede the healing process and promote granuloma development.
Umbilical Stump Colonization by Bacteria: When harmful bacteria colonize the umbilical stump, it can lead to inflammation and contribute to granuloma formation.
Umbilical Stump Tied with Unsterilized Material: Using unsterilized materials to tie off the umbilical stump can introduce bacteria and increase the risk of granuloma development.
Umbilical Stump Repeatedly Irritated: Repeated irritation of the umbilical stump, such as rubbing or scratching, can prolong healing and result in granuloma formation.
Umbilical Stump Infected with Fungi: In rare cases, fungal infections in the umbilical stump can occur, leading to granuloma formation.

Symptoms

Comprehensive list of symptoms associated with umbilical granuloma,

Persistent Oozing: Umbilical granuloma may result in a persistent discharge of clear or yellowish fluid from the belly button area. This is a common symptom to watch out for.
Redness and Inflammation: The area around the belly button may become red and inflamed. It may appear swollen and feel warm to the touch.
Bleeding: Sometimes, umbilical granulomas can bleed on their own or with slight stimulation. If you notice any bleeding, it is important to seek medical attention.
Foul Odor: An unpleasant odor may emanate from the umbilical area due to the accumulation of discharge. This odor is typically different from the normal smell associated with a healthy belly button.
Moist or Wet Appearance: The granuloma may appear wet or moist due to the constant discharge. This can be an indication that the healing process is not progressing as expected.
Small Red Bump: Initially, the umbilical granuloma may present as a small, reddish bump near the belly button. It may resemble a small blister or pimple.
Excessive Crying: Infants with umbilical granuloma may exhibit signs of discomfort or pain, leading to increased fussiness and crying.
Poor Appetite: Some babies may experience a decreased appetite due to discomfort caused by the umbilical granuloma.
Irritability: The presence of a granuloma can cause irritability in infants, making them more fussy and difficult to soothe.
Tender or Sensitive Belly Button: The area around the belly button may be tender or sensitive to touch. Infants may react with discomfort when it is touched or cleaned.
Crusty or Scaly Surface: Over time, the granuloma may develop a crusty or scaly surface. This can further contribute to irritation and discomfort.
Pus-like Discharge: In some cases, the discharge from the umbilical granuloma may become thicker and resemble pus. This indicates the need for medical attention.
Slow Healing: The granuloma may persist and fail to heal on its own. If you notice that it is not improving or getting worse over time, a medical evaluation is necessary.
Recurrence: After initial treatment, there is a chance of the granuloma reoccurring. This may require additional medical intervention to resolve the issue.
Swelling: The granuloma and the surrounding area may become swollen and puffy, leading to further discomfort for the baby.
Crusting and Drying: The discharge from the granuloma can crust and dry up, causing the surface to harden and potentially crack.
Skin Discoloration: The skin around the umbilical granuloma may appear darker or discolored compared to the surrounding skin.
Discomfort during Diaper Changes: The constant rubbing of the diaper against the granuloma can cause discomfort during diaper changes, leading to increased fussiness.
Slow Navel Cord Separation: In some cases, umbilical granuloma can delay the separation of the navel cord stump. This can be an additional sign to watch for.
Visible Granuloma: The presence of a small, fleshy lump near the belly button is the most visible symptom of umbilical granuloma.

Diagnosis

It occurs when the tissue at the site of the umbilical cord does not heal properly after the cord falls off.

Visual Examination: The first step in diagnosing an umbilical granuloma is a visual examination. A healthcare professional will inspect the belly button area to identify any signs of abnormal growth or discharge.
Medical History: The doctor may ask questions about the baby’s medical history, including any previous umbilical cord-related issues or infections.
Physical Examination: A physical examination involves checking for any tenderness, redness, swelling, or unusual discharge around the umbilical area.
Ultrasound: An ultrasound uses sound waves to create images of the umbilical area. This test helps determine the size, location, and composition of the granuloma.
Blood Tests: Blood tests may be conducted to check for signs of infection or other underlying conditions that could be contributing to the umbilical granuloma.
Swab Culture: A swab culture involves taking a sample of any discharge from the umbilical area. The sample is sent to a laboratory to determine if there is an infection present and to identify the specific bacteria causing it.
X-ray: In some cases, an X-ray may be performed to rule out any other possible conditions that could be causing symptoms similar to umbilical granuloma.
Digital Photography: Digital photography can be used to document the appearance and progress of the umbilical granuloma over time. This visual record helps doctors monitor the condition and assess the effectiveness of treatment.
Biopsy: If the doctor suspects an unusual or persistent granuloma, a small sample of tissue may be removed for further examination under a microscope. This procedure is called a biopsy.
Complete Blood Count (CBC): A complete blood count provides information about the overall health of the patient by measuring the levels of different blood cells, such as red and white blood cells.
C-reactive Protein (CRP) Test: The C-reactive protein test helps determine the presence of inflammation in the body, which could indicate an infection related to the umbilical granuloma.
Erythrocyte Sedimentation Rate (ESR): The ESR test measures the rate at which red blood cells settle in a test tube. It can indicate the presence of inflammation or infection.
Wound Culture: A wound culture involves taking a sample from the umbilical granuloma to identify any bacteria present and determine the most effective antibiotic treatment.
Fungal Culture: In some cases, a fungal culture may be conducted to rule out the presence of fungal infections that could be contributing to the umbilical granuloma.
Skin Scraping: A skin scraping procedure involves gently scraping the surface of the umbilical granuloma to check for fungal elements or other microscopic abnormalities.
Genetic Testing: Genetic testing may be recommended if there is suspicion of an underlying genetic condition that could be causing the umbilical granuloma.
Immunological Testing: Immunological testing helps assess the functioning of the immune system, which can provide valuable insights into the body’s ability to fight off infections and heal properly.
Serologic Tests: Serologic tests involve analyzing blood samples to detect specific antibodies that may be associated with certain infections or autoimmune disorders.
Allergy Testing: If there is a suspicion of allergies contributing to the umbilical granuloma, allergy testing may be performed to identify potential triggers.
Thyroid Function Tests: Thyroid function tests help evaluate the function of the thyroid gland, which plays a crucial role in regulating metabolism and overall growth and development.
Stool Analysis: A stool analysis may be requested to check for any signs of gastrointestinal infections or abnormalities that could be related to the umbilical granuloma.
Urine Analysis: Urine analysis helps assess kidney function and can provide insights into any underlying urinary tract infections that may be contributing to the condition.
Radiographic Studies: Radiographic studies, such as a CT scan or MRI, may be recommended if there is a suspicion of more complex underlying issues or complications.
Allergic Patch Test: An allergic patch test can be used to determine if certain substances are triggering an allergic reaction in the umbilical area.
Thyroid Imaging: Thyroid imaging techniques, such as ultrasound or radioactive iodine scans, may be performed to assess the structure and function of the thyroid gland.
Abdominal CT Scan: An abdominal CT scan provides detailed images of the abdomen, helping to identify any potential abnormalities or complications associated with the umbilical granuloma.
Endoscopy: In some cases, an endoscopy may be performed to examine the gastrointestinal tract for any abnormalities or underlying conditions related to the umbilical granuloma.
Laparoscopy: Laparoscopy involves inserting a small camera through a small incision in the abdomen to examine the internal organs and identify any potential complications or causes of the umbilical granuloma.
Skin Prick Test: A skin prick test can help determine if the umbilical granuloma is caused by an allergic reaction to specific substances.
Exploratory Surgery: Exploratory surgery is considered a last resort when all other diagnostic methods have been exhausted. It involves making an incision in the abdomen to directly visualize and identify any underlying issues causing the umbilical granuloma.

Treatment

While it may look concerning, umbilical granulomas are generally harmless and can be easily treated.

Saline Solution Treatment:

One of the simplest and most widely used treatments for umbilical granuloma is the application of saline solution. A saline solution is a mixture of salt and water that helps cleanse and heal the affected area. To apply this treatment, follow these steps:

Dissolve half a teaspoon of salt in a cup of warm water to create the saline solution.
Soak a clean cotton ball or gauze pad in the solution.
Gently press the soaked cotton ball or pad onto the umbilical granuloma for a few minutes.
Repeat this process two to three times a day for several days until the granuloma dries up and falls off.

Silver Nitrate Treatment:

Another commonly used treatment for umbilical granuloma is the application of silver nitrate. Silver nitrate is a chemical compound that helps cauterize the tissue, leading to the drying and shrinking of the granuloma. Here’s how to administer this treatment:

Visit your healthcare provider or a medical professional who can apply silver nitrate.
They will gently clean the area with saline solution.
Using a silver nitrate stick, they will apply it directly to the granuloma.
This procedure may cause a mild burning or stinging sensation, but it’s generally well-tolerated.
You may need to repeat the treatment once or twice, depending on the size and persistence of the granuloma.

Cryotherapy Treatment:

Cryotherapy involves the use of extremely cold temperatures to freeze and destroy the granuloma tissue. While this treatment option is less commonly used, it can be highly effective. Here’s what you should know:

Consult a healthcare professional who can perform cryotherapy.
They will use a specialized instrument, such as a cryoprobe, to freeze the granuloma.
The extreme cold causes the cells in the granuloma to die and eventually fall off.
Cryotherapy may cause some discomfort or a brief stinging sensation during the procedure.
It usually requires only one session to eliminate the granuloma.

Cauterization Treatment:

Cauterization is a treatment method that involves the controlled application of heat or a chemical agent to remove granuloma tissue. Here’s how it works:

Seek assistance from a healthcare provider experienced in cauterization.
They will clean the area around the granuloma.
Using a heated instrument or a chemical agent, they will carefully apply it to the granuloma to burn or dissolve the tissue.
Local anesthesia or numbing cream may be used to minimize any discomfort.
Cauterization is generally a quick procedure that effectively eliminates the granuloma in one session.
