Fibrous Hamartoma of Infancy (FHI) is a rare and benign tumor that is typically seen in children under the age of two. It usually appears as a soft, fleshy lump that can be found anywhere on the body, but most often in the head and neck area. FHI is an uncommon disorder, with an estimated incidence of 1 in 100,000 live births. It is most commonly seen in infants between the ages of one and six months. It typically does not cause any symptoms or discomfort, although some cases may present with pain or swelling due to the size of the mass. Treatment is usually surgical removal of the mass, although some cases may require additional therapies such as chemotherapy or radiation therapy. Fibrous Hamartoma of Infancy (FHI) is a benign tumor of infancy. It is characterized by a collection of fibrous tissue and fat cells that typically occur in the chest or neck area. FHI is usually present at birth, but may not be visible until later in life. It is usually painless and does not cause any symptoms, although it can cause a mass to be seen in the affected area. Treatment for FHI typically includes observation over time, but if the mass becomes large or painful, surgical removal may be necessary.

Causes of Fibrous Hamartoma of Infancy

Fibrous hamartoma of infancy (FHI) is a benign skin lesion that typically appears in newborns and infants. The cause of FHI is unknown, but there are several possible contributing factors that may be associated with the development of the condition:

  • Genetic predisposition: FHI may be caused by a genetic mutation or abnormality that is passed down from parent to child.
  • Environmental exposure: Exposure to certain environmental factors, such as ultraviolet light or toxins, may increase the risk of FHI.
  • Immune system disorders: Certain immune system disorders, such as allergies or autoimmune diseases, may contribute to the development of FHI.
  • Hormone imbalances: Hormonal imbalances can also lead to the development of FHI.

Though it is not known exactly what causes FHI, these potential contributing factors have been identified and should be considered when diagnosing and treating this condition. It is important for patients and their families to discuss any potential causes with their doctor in order to determine the best course of action. With proper care and management, most cases of FHI can be successfully treated.

Fibrous Hamartoma of Infancy Symptoms

Fibrous hamartoma of infancy (FHI) is a benign tumor that mostly affects newborns and infants. It is a soft tissue tumor that can vary in size and usually occurs in the chest, abdomen, neck or arms. The exact cause of FHI is unknown, but it is believed to be caused by an overgrowth of fibrous tissue in the affected area. FHI is not cancerous, but it can interfere with normal growth and development if left untreated.

The most common symptom of FHI is a lump or swelling in the affected area. The lump may be firm and rubbery, or soft and compressible. It may grow slowly over time, or remain unchanged for months or years. Other symptoms may include pain, redness on the skin around the lump and difficulty breathing if the lump is near the chest wall.

Diagnosis of FHI typically begins with a physical exam and imaging tests such as X-rays and ultrasounds to get an idea of where the tumor is located and how large it is. If necessary, a biopsy may be performed to confirm the diagnosis.

Treatment for FHI usually involves surgery to remove the tumor completely. Depending on its size and location, this can be done either through open surgery or laparoscopy (minimally invasive surgery). In some cases, medication may be used in combination with surgery to reduce inflammation or reduce pain associated with FHI. In rare cases where the tumor cannot be removed entirely, radiation therapy may be used to shrink it down.

Most patients with fibrous hamartoma of infancy have no long-term effects from their condition as long as it is treated promptly and appropriately. However, patients should follow up with their doctor periodically to ensure that any tumors are not growing back after treatment or causing any other complications related to their condition.

Diagnosis of Fibrous Hamartoma of Infancy

Fibrous hamartoma of infancy (FHI) is a benign soft tissue tumor that occurs in infants and young children. It is most commonly found in the chest wall, but can also occur in other parts of the body. Diagnosis of FHI can be challenging due to its nonspecific clinical presentation and lack of distinct imaging findings. Here, we will discuss the diagnostic approach for FHI.

Clinical Presentation:

FHI typically presents as a firm, solid, and painless mass in an infant or young child. The mass usually does not change in size or shape over time. It may grow slowly over time, but this is not always the case. It is important to note that FHI can present with different signs and symptoms depending on its location within the body. For example, FHI located in the chest wall may cause respiratory symptoms such as shortness of breath or coughing.

Imaging Studies:

Imaging studies are often used to confirm a diagnosis of FHI and to assess its extent. A chest X-ray may reveal an abnormal mass in the chest wall, while an ultrasound may show a well-defined solid lesion with characteristic echotexture changes and hypoechoic areas within it. Magnetic resonance imaging (MRI) can be used to further characterize the lesion and assess its extent.


A biopsy can provide definitive diagnosis of FHI by confirming the characteristic histologic features on microscopic examination. It can also provide information about the extent of the lesion which is important for planning treatment and follow-up care.


Once a diagnosis has been made, treatment typically consists of surgical excision if feasible. Close follow-up is recommended after surgery to monitor for recurrence or progression to malignancy, which is rare but possible with FHI lesions located outside the chest wall.

In summary, diagnosis of fibrous hamartoma of infancy requires careful clinical evaluation and appropriate imaging studies followed by biopsy if needed for confirmation.

Fibrous Hamartoma of Infancy

Fibrous hamartoma of infancy (FHI) is a rare benign tumor that usually appears in newborns and infants. It is characterized by a lesion composed of mature connective tissue and fibroblasts, with a variable admixture of fat, smooth muscle, and blood vessels. FHI typically grows slowly and can occur anywhere on the body. It is most commonly found on the chest wall, back, or abdomen. Treatment options for FHI vary depending on the size and location of the tumor.


The diagnosis of FHI is made through clinical examination and imaging studies such as MRI or ultrasound. To confirm the diagnosis, a biopsy may be performed to examine a sample of the tissue under a microscope.

Treatment Options

The goal of treatment for FHI is to remove the tumor without causing any damage to surrounding tissues or organs. The primary treatment option for FHI is surgical excision. This involves removing the entire tumor along with a wide margin of healthy tissue around it to ensure that all cancerous cells have been removed. Other methods such as cryotherapy or laser ablation may be used to reduce the size of the tumor prior to surgery if needed. In some cases, observation may be recommended if there are no signs of growth or if there is a risk that surgery could cause more harm than good.

For tumors that cannot be surgically removed or are at risk for recurrence after surgery, chemotherapy may be an option. Chemotherapy drugs are administered intravenously or orally depending on the type and severity of the tumor. Radiation therapy may also be used in some cases to shrink tumors that cannot be surgically removed or reduce their risk for recurrence after surgery.


Once treatment has been completed, it is important to follow up with your doctor regularly for check-ups and imaging tests to monitor for any signs of recurrence or new tumors developing nearby. If any new tumors appear after treatment, they should be evaluated promptly as they could indicate malignancy or other complications requiring further treatment.

Prognosis for Fibrous Hamartoma of Infancy

Fibrous Hamartoma of Infancy (FHI) is a benign tumor that occurs most commonly in infants. While FHI is typically benign and non-cancerous, it can have long-term implications on the health and development of an infant. Fortunately, the prognosis for FHI is generally positive with early diagnosis and proper treatment.

When diagnosed early, FHI can be treated with surgical excision with minimal risk to the patient or long-term complications. In such cases, the prognosis is favorable as full recovery is expected after the tumor has been removed. However, if not detected early enough, surgery may be more complicated and recurrences are more likely to occur.

In addition to surgical removal, other treatments may also be necessary depending on the size and location of the tumor. For example, radiation therapy may be used if the tumor is too large or located in a difficult area to remove surgically. In cases where radiation therapy is necessary, there may be side effects from the treatment that can cause long-term health problems for the patient.

Prognosis for FHI also depends on how quickly it is diagnosed and treated. If it is detected late in infancy or childhood, recurrence rates are higher and there may be more long-term complications associated with it. Early diagnosis and treatment are key to getting a good outcome for this condition as well as reducing any potential risks associated with delayed diagnosis or treatment.

Overall, FHI has a good prognosis when addressed promptly and accurately through surgery or other treatments as necessary. With proper diagnosis and treatment, infants can make a full recovery without any long-term health implications from their condition.

Fibrous Hamartoma of Infancy

Fibrous hamartoma of infancy (FHI) is a rare benign tumor that usually develops in infants and young children. FHI is most commonly found on the trunk, neck, or shoulder of an infant. It usually appears as a firm, rubbery lump that can range in size from a few millimeters to several centimeters. Because FHI is usually harmless and rarely requires treatment, many parents opt to manage it at home.


A diagnosis of FHI can be made by a physical examination by your doctor. In some cases, imaging tests such as X-rays or ultrasound may be used to confirm the diagnosis. If the doctor suspects that the lump may not be FHI, further tests such as a biopsy may be recommended.

Managing at Home

In most cases, FHI does not require any treatment and can be managed at home with careful observation. It is important to watch for any changes in size or shape of the lump, as well as any signs of infection such as redness or swelling around the area. If any of these signs are present, it is important to contact your doctor for further evaluation.

To keep the area clean and dry while managing at home, you can use mild soap and water to gently wash the area daily. Avoid applying any lotions or creams to the area unless instructed by your doctor. If your child experiences discomfort due to rubbing from clothing or other items, you can use over-the-counter ointments to provide relief.

When To See A Doctor

It is important to have regular check-ups with your doctor while managing fibrous hamartoma of infancy at home. Your doctor will monitor changes in size and shape of the lump over time and make sure there are no signs of infection present in the area. In some cases, your doctor may recommend surgery if there are concerns about growth or malignancy of the tumor; however this is rare and usually only recommended if other treatments have failed or if it is causing significant discomfort for your child.

If you notice any sudden changes in size, shape, color or texture of the lump you should contact your doctor immediately for further evaluation. Signs of infection such as redness or swelling around the area should also be reported right away so that appropriate treatment can be given if necessary.
