What Causes Lipoma Disease?

Lipoma Disease Causes, Risk Factors & How to Manage It

Discovering a lump of soft tissue under the skin may raise some concern and curiosity. These bumps can appear unexpectedly on many people's necks, shoulders, backs, or arms.

Nevertheless, it is crucial to be aware of their presence to maintain well-being and proper monitoring or treatment in case of necessity. The subsequent sections will delve into the causes of their development, their presentation, and the holistic options regarding their care and management.

What is Lipoma Disease?

Lipoma is a benign tumour that is common and composed of mature fat cells. These soft, mobile growths normally develop immediately beneath the skin, are slow-growing, and are often painless. Although they are mostly harmless, it is relevant to know their causes, diagnosis, and management to have peace of mind and be able to take good care of oneself.

What are the Causes of Lipoma Disease?

The exact cause of lipoma formation remains unclear, but several risk factors are well-established:

1. Genetic Predisposition
   
   
   • Lipomas tend to occur in families; hereditary disorders such as familial multiple lipomatosis indicate an autosomal pattern.
   • A significant number of lipomas, though not a majority, have chromosomal abnormalities. The most common finding is a rearrangement of chromosome 12q13-15, which involves the HMGA2 gene.
2. Age and Gender
   
   
   • Most lipomas occur between the ages of 40 and 60, but they may happen at any age.
   • It is slightly more prevalent in men, but women may get lipomas as well.
3. Associated Medical Conditions
   
   
   • There is an association between lipomas and obesity, high cholesterol, and diabetes.
   • Multiple lipomas may be seen in some genetic disorders, including Cowden syndrome, Gardner syndrome, Madelung disease, and Dercum disease.
4. Other Factors
   
   
   • Trauma has occasionally been implicated in lipoma formation, though evidence is limited.
   • Physical inactivity and alcoholism (observed in Madelung disease) are lifestyle factors that may increase risk.

What are the symptoms of lipoma disease?

Lipomas typically present with:

• Soft, doughy lump just under the skin.
• Moves easily when pressed (not fixed to deeper tissues).
• Slow-growing, typically over months or even years.
• Size range is usually 1–5 cm, but larger "giant lipomas" over 10 cm can occur.
• Location: Common on shoulders, back, neck, arms, and thighs; occasionally deeper in muscles or organs.
• Pain: Usually painless unless pressing on nerves or containing blood vessels (angiolipoma subtype).

 When it Might Be Painful

• If the lipoma contains many blood vessels (angiolipoma)
• If it presses on nearby nerves or tissues
• If it grows in a tight or sensitive area

Most people only have one lipoma, but some may develop several.

What is the diagnosis of lipoma disease?

The following methods can diagnose lipomas:

• Physical examination is typically sufficient to identify a lipoma. A doctor will feel the lump to check if it’s soft, movable, and painless, which are classic signs of a lipoma.
• Imaging(ultrasound, CT, MRI) is used to exclude liposarcoma when lipomas are large, deep, fast‑growing, or painful.
• Biopsy may be performed if cancer is suspected or the diagnosis is unclear.

What are the treatment options for lipoma disease?

Lipomas are usually harmless, but getting any new or growing lump checked out is always smart.

Observation

• Most lipomas do not require intervention, especially if asymptomatic.

Surgical Excision

• Complete removal, including the capsule, is the preferred option to minimise recurrence.
• Typically done under local anaesthesia with same-day discharge.

Minimal Excision Extraction

• A technique that combines a small incision with squeezing out the lipoma, leaving less scarring, but it is not always suitable for larger or deeper ones.

Liposuction

• Used for larger lipomas or multiple growths; results in fewer scars but may have a higher chance of recurrence due to incomplete removal.

Steroid or Lipotropic Injections

• Injectables like steroids or phosphatidylcholine can shrink lipomas, though outcomes vary. Side effects include skin discolouration or fat breakdown.

What is the prevention & care of lipoma disease?

While lipomas can’t always be prevented, some lifestyle choices may help reduce your risk or manage existing ones:

• Healthy lifestyle: Normal weight, regular exercise, and management of metabolic disorders may reduce risk.
• Regular monitoring: Report any growth in size, pain, or firmness to your doctor promptly.

What are the risks and complications of lipoma disease?

Here’s a breakdown of the risks and potential complications you should be aware of:

• Recurrence: 1–2% after excision; rates may be higher with liposuction.
• Nerve compression: If a lipoma grows near a nerve, it can press on it and cause pain, tingling, or numbness.
• Restricted movement: Large or deep lipomas, especially near joints or muscles, can limit mobility or cause discomfort during movement.
• Surgical complications include infection, scarring, bleeding, and nerve injury in sensitive locations.
• Risk of misdiagnosis: A lump that seems like a lipoma could be a liposarcoma, a cancerous tumour in sporadic cases. Warning signs include rapid growth, firmness, or pain.
