What is a Lipoma?

A lipoma is a type of growth that occurs under the skin, composed of fat cells. It is a non-cancerous (benign) lump that forms due to an overgrowth of fat cells in the fatty layer of the skin [1]. Lipomas are common and can appear anywhere on the body, but they most often develop on the shoulders, trunk, neck, or armpits [5].

Characteristics of a Lipoma

Lipomas are typically soft, rubbery, and painless lumps that move easily when touched. They can range in size from small to quite large, with some growing up to 10 cm in diameter [9]. The overlying skin may appear normal, but the lipoma itself will be palpable (can be felt) under the skin.

Types of Lipomas

While most lipomas are solitary growths, they can sometimes occur in clusters or as part of a larger condition. However, it's essential to note that lipomas are not cancerous and do not typically require treatment unless they become symptomatic or cause discomfort [7].

Symptoms and Diagnosis

Lipomas may be asymptomatic, but some people may experience pain or discomfort if the growth becomes irritated or inflamed. A diagnosis is usually made through physical examination and medical history. Imaging tests like ultrasound or MRI may also be used to confirm the presence of a lipoma.

Treatment Options

In most cases, lipomas do not require treatment unless they become symptomatic or cause concern. However, if you're experiencing discomfort or pain due to a lipoma, your doctor may recommend removal through surgery [8].

Based on the provided context, here are the signs and symptoms of skin lipoma:

1. Soft and squishy texture: Lipomas feel soft to touch and can be described as "squishy".
2. Small size: They can vary in size from a pea to a few centimeters across.
3. Location: Lipomas are usually located just under the skin, but can develop anywhere on the body.
4. Movement with finger pressure: Lipomas can move slightly under your skin if you apply gentle finger pressure.
5. Non-painful or tender: Most lipomas are not painful or tender to the touch.
6. Dome-shaped appearance: Lipomas are usually shaped like a dome and feel soft and rubbery.
7. Size variation: They can range from small (pea-sized) to larger (grapefruit-sized).

It's essential to note that while lipomas are generally harmless, it's still important to consult with a healthcare provider if you notice any changes or symptoms, such as sudden pain or tenderness.

Treatment Options for Skin Lipomas

According to various medical sources, non-surgical treatment options are now common for lipomas, including:

• Steroid injections: This type of treatment can help shrink a tumor and is often used as an alternative to surgery [6].
• Liposuction: A minimally invasive procedure that uses a needle and syringe to remove the fatty tissue [1].

These non-excisonal treatments are considered effective alternatives to surgical removal, which may result in scarring and bruising.

Other Treatment Options

While not as common, other treatment options for lipomas include:

• Surgical removal: This is still considered a viable option for larger lipomas or those that cause discomfort [2].
• Intralesional lipolysis with deoxycholic acid: A safe and effective therapeutic option for lipomas, which has been shown to be effective in reducing the size of the tumor [7].

Prevention

It's worth noting that lipomas cannot be prevented. However, if you're experiencing discomfort or cosmetic concerns due to a lipoma, there are various treatment options available.

Differential Diagnosis for Skin Lipoma

A skin lipoma, also known as a benign fatty tumor, can be challenging to diagnose due to its similarity in appearance with other masses or tumors. The differential diagnosis for a skin lipoma includes:

• Sebaceous cyst: A common skin lesion that can mimic the appearance of a lipoma [1].
• Abscess: A pocket of pus that can form under the skin, which may be mistaken for a lipoma [1].
• Benign cyst: A fluid-filled sac that can occur in various parts of the body, including the skin [2].
• Dermatofibroma: A small, benign growth that can appear on the skin, often as a result of injury or trauma [2].
• Ganglion cyst: A type of cyst that can form on the tendons or joints, which may be mistaken for a lipoma [3].
• Liposarcoma: A rare and malignant tumor that can occur in the soft tissues, including the skin [4]. However, this is relatively rare and usually occurs in older adults.
• Angiolipoma: A type of benign fatty tumor that can occur in the skin, which may be mistaken for a lipoma [5].
• Hibernoma: A rare benign tumor that can occur in the soft tissues, including the skin [5].

It's essential to note that while these conditions can mimic the appearance of a lipoma, they often have distinct characteristics and symptoms. A proper diagnosis by a healthcare professional is necessary to determine the exact nature of the skin lesion.
