Familial Multiple Lipomatosis: Signs, Causes, And How To Treat
Familial multiple lipomatosis is a rare genetic disorder that causes the growth of multiple benign fatty lumps under the skin. This condition may run in families and usually appears in adulthood. The exact cause of familial multiple lipomatosis is linked to specific genetic mutations. These mutations can lead to an abnormal growth of fat cells, resulting in the development of lipomas throughout the body. Understanding the genetic basis of this condition is crucial for diagnosis and management. If you suspect you may have familial multiple lipomatosis, consult a healthcare professional for proper evaluation and guidance.
What Are the Symptoms of Familial Multiple Lipomatosis?
These growths, called lipomas, are usually painless but can sometimes be tender. They commonly appear on the shoulders, back, arms, and thighs. In some cases, lipomas can grow in large numbers and affect a person's appearance. Seeking medical evaluation is important for proper diagnosis and management.
- Multiple soft, rubbery lumps under the skin that are painless to the touch are a common symptom of familial multiple lipomatosis.
- Some individuals with familial multiple lipomatosis may notice a gradual increase in the size and number of lipomas over time, particularly in the arms, thighs, and trunk areas.
- In some cases, the presence of multiple lipomas may cause cosmetic concerns due to their visible appearance on the body.
- Occasionally, individuals with familial multiple lipomatosis may experience discomfort or tenderness if a lipoma presses on nearby nerves or tissues.
- Rarely, some people with this condition may develop lipomas in internal organs such as the intestines, leading to symptoms like abdominal pain and digestive issues.

These mutations result in the development of multiple benign fatty tumors, known as lipomas, in different parts of the body. The condition is inherited in an autosomal dominant pattern, meaning a person only needs to inherit one copy of the mutated gene from either parent to develop the disorder.
- Familial multiple lipomatosis can be caused by mutations in the adiponectin receptor 1 (ADIPOR1) gene.
- Another cause of familial multiple lipomatosis is mutations in the peroxisome proliferator-activated receptor gamma (PPARG) gene.
- In some cases, familial multiple lipomatosis is linked to mutations in the phosphatase and tensin homolog (PTEN) gene.
- Genetic variations in the lamin A/C (LMNA) gene have also been identified as a potential cause of familial multiple lipomatosis.
- Familial multiple lipomatosis may result from alterations in the CCAAT/enhancer binding protein alpha (CEBPA) gene.
Types Of Familial Multiple Lipomatosis
Familial multiple lipomatosis can be classified into several types based on the pattern and location of the fatty tissue growth. These types include Dercum's disease, familial multiple lipomatosis type 1 and type 2, and adiposis dolorosa. Each type presents with distinct characteristics and symptoms, such as multiple painful fatty lumps under the skin. Proper diagnosis and management are essential for individuals with familial multiple lipomatosis.
- Madelung's Disease, also known as multiple symmetric lipomatosis, is a rare disorder characterized by the growth of benign fat deposits around the neck, shoulders, and upper arms, resulting in a disfiguring appearance.
- Familial multiple lipomatosis type 1 is an inherited condition that causes the development of multiple lipomas, which are non-cancerous fatty tumors, typically found on the torso and limbs of affected individuals.
- Bannayan-Riley-Ruvalcaba Syndrome is a genetic disorder associated with multiple lipomas, macrocephaly (enlarged head size), intellectual disability, and other features, presenting a complex clinical picture that requires comprehensive management.
- Familial multiple lipomatosis type 2 is another inherited condition that involves the development of multiple lipomas, similar to type 1, but may present with additional features or different patterns of lipoma distribution.
Risk Factors
Familial multiple lipomatosis risk factors include genetics, with a family history of the condition increasing the likelihood of developing it. Age is also a factor, as lipomas tend to appear in adulthood. Additionally, certain genetic syndromes and hormonal imbalances may contribute to the development of multiple lipomas. Maintaining a healthy weight and lifestyle can help reduce the risk.
- Genetics plays a significant role in familial multiple lipomatosis, with a family history of the condition being a major risk factor.
- Being overweight or obese increases the likelihood of developing multiple lipomas, especially in familial cases.
- Certain genetic syndromes, such as Gardner syndrome or adiposis dolorosa, are associated with an increased risk of familial multiple lipomatosis.
- Hormonal imbalances, such as those seen in conditions like Cushing's syndrome or hypothyroidism, can contribute to the development of lipomas in individuals with a genetic predisposition.
- Age is also a risk factor for developing lipomas, with familial multiple lipomatosis typically presenting in adulthood, although cases in children have been reported.

Diagnosis of Familial Multiple Lipomatosis
A genetic test may also be conducted to confirm the presence of specific gene mutations linked to the condition. A healthcare provider will work closely with the patient to accurately diagnose familial multiple lipomatosis and develop a personalized treatment plan.
- Physical Examination: The presence of multiple lipomas in various parts of the body can be identified through a thorough physical examination by a healthcare provider.
- Imaging Studies: Diagnostic methods such as ultrasound, MRI, or CT scans may be performed to visualize the size, location, and number of lipomas present.
- Genetic Testing: Familial multiple lipomatosis can be confirmed through genetic testing to identify any underlying genetic mutations that may be causing the condition.
- Biopsy: In some cases, a biopsy of a suspected lipoma may be recommended to rule out other possible causes and to confirm the diagnosis of familial multiple lipomatosis.
- Family History Assessment: Obtaining a detailed family history can provide valuable information about any relatives who may have similar symptoms, helping to identify a genetic pattern and confirming the likelihood of familial multiple lipomatosis.
Treatment for Familial Multiple Lipomatosis
Treatment for familial multiple lipomatosis focuses on managing symptoms and addressing cosmetic concerns. Surgical removal of bothersome lipomas is a common approach, but recurrence is possible. Liposuction may also be considered. Monitoring for new growths and maintaining a healthy weight are important. Consult with a healthcare provider to discuss the best treatment plan for your specific situation.
- Surgical excision is often considered the primary treatment option for familial multiple lipomatosis, especially for symptomatic or cosmetically bothersome lipomas.
- Liposuction can be a viable alternative for removing multiple lipomas in a less invasive manner, particularly for smaller, more superficial lipomas.
- In cases where surgical intervention is not feasible or preferred, steroid injections may be used to reduce the size and symptoms of lipomas associated with familial multiple lipomatosis.
- Medications like oral retinoids have shown some promise in reducing the growth of lipomas in familial multiple lipomatosis, although further research is needed to establish their efficacy.
- Regular monitoring and surveillance by a healthcare provider are essential for individuals with familial multiple lipomatosis, as the condition tends to be progressive.
