Dermatofibromas

Dermatofibromas are common, benign skin growths that typically appear as small, firm, raised bumps on the skin. While harmless, they can sometimes be bothersome or uncomfortable due to their location or appearance. At Skin Revision in Beaconsfield, we provide safe and effective treatment options for the removal of Dermatofibromas.

In this post, we’ll explore what Dermatofibromas are, their causes, symptoms, and the necessary treatments for those who wish to remove these common skin lesions.

What is a Dermatofibroma?

Dermatofibromas are non-cancerous growths that usually appear as small, round or oval-shaped lumps on the skin. They range from 5-10mm in diameter and have a firm, button-like feel. These common skin lesions, sometimes referred to as benign Fibrous Histiocytomas, are generally painless, but they may cause discomfort if located in areas prone to friction, such as the legs, arms, or shoulders. These growths are most often seen in adults and are more common in women than men.

While they are generally flesh-coloured, Dermatofibromas may appear pink, brown, or red, depending on the individual’s skin tone. One distinguishing feature is the “dimple sign” — when the growth is pinched, it often dimples inward.

Causes of Dermatofibroma

The exact cause of Dermatofibromas is unknown, but they are thought to develop due to:

1. Insect Bites or Stings: Dermatofibromas may form as a reaction to an insect bite or sting, which can lead to an overproduction of fibrous tissue in the skin.

2. Skin Trauma or Injury: Even minor cuts or abrasions can trigger the growth of a Dermatofibroma, as the body responds by producing excess connective tissue in the area.

3. Genetics: While not directly inherited, a family history of skin growths may make certain individuals more prone to developing dermatofibromas.

4. Immune Response: Some studies suggest that Dermatofibromas may form as a response to inflammation or immune reactions in the skin.

The body may respond to these possible causes above by creating a small overgrowth of fibrous tissue, resulting in the formation of a Dermatofibroma.

Symptoms of Dermatofibroma

Dermatofibromas are usually easy to identify based on their appearance and texture. Common symptoms include:

● Firm, Raised Bumps: These growths are typically round, firm, and slightly raised, with a diameter of 5-10mm.

● Varied Colour: Dermatofibromas are often flesh-coloured but may range from pink to brown, depending on skin tone.

● Itching or Sensitivity: While usually painless, dermatofibromas may cause mild itching or sensitivity, especially if they’re located in areas where clothing rubs against them.

● Dimpling Effect: When pinched, a Dermatofibroma often dimples inward, a unique characteristic known as the “dimple sign.”

Dermatofibromas are generally harmless and do not necessarily require a non-surgical treatment. However, they may cause some discomfort or maybe unsightly to some. Because of these reasons, some people reach out to cosmetic clinics, such as Skin Revision, for a consultation to remove the Dermatofibroma.

Effective Treatments for Dermatofibromas

Most Dermatofibromas are left untreated as they are benign and pose no health risks. However, at Skin Revision, we offer a non-invasive treatment for those who wish to remove the appearance of Dermatofibromas for aesthetic reasons or to improve comfort.

Cryopen Treatment

Medical-grade CryoPen Cryotherapy involves freezing the Dermatofibroma with nitrous oxide at the extremely low temperature of -89 degrees celcius. The extreme cold causes the fibrous tissue to break down and gradually reduce in size. Over time, the treated area may scab over and fall off as the skin heals. Using CryoPen causes no permanent scaring to the area treated.

● Benefits: Non-invasive, quick, and suitable for small to medium Dermatofibromas.

● Downtime: Minimal, with only mild redness or scabbing for a few days after treatment.

Cryotherapy may require a second treatment, depending on the size of the Dermatofibroma.

Topical treatments for Texture and Colour

While topical treatments cannot remove Dermatofibromas, they may help improve skin texture and even out pigmentation post-removal. Retinoid creams or serums with mild exfoliating properties can enhance skin renewal and may reduce residual discolouration. During your consultation with your skin therapist and also post-treatment, you will be advised of any creams or serums that may help quicken up the healing process.

Frequently Asked Questions

Will Dermatofibromas grow back after treatment? Dermatofibromas typically do not grow back once fully removed. However, if the entire lesion is not treated, there may be some regrowth. Any follow-up treatment is quicker and will cost less.

Are Dermatofibromas dangerous? No, Dermatofibromas are benign and not harmful. They are purely cosmetic concerns, though some individuals may seek treatment if they cause discomfort.

Are Dermatofibromas more common in men than women? They are common across all ages groups, but actually they are more common in those aged 20–50 years, and more common with women.

Can they be removed surgically? Yes, although surgery is very uncommon for these benign lesions. There is always the risk of scarring if an individual opts for surgery.

Will Dermatofibromas just disappear on their own and therefore no treatment is needed? It has been known for the lesions to get less itchy over time, get softer and flatten off slightly.

Is there a risk of scarring? Our CryoPen treatment is designed to minimise the risk of scarring. However, as with any skin treatment, there may be minor scarring in some cases. All cases treated at Skin Revision have left no permanent scarring.

Can I get Dermartofibroma removed by my GP or the NHS in the UK? No, currently the NHS are not performing non-surgical treatments for lesions that they regard as cosmetic. This includes Dermatofibromas.

Is the treatment to remove Dermartofibromas painful? Using the CryoPen cryotherapy method, the sensation of pinpoint accurate sprays of nitrous oxide are exceptionally cold and a little prickly. However, the sensations are only on the lesion and only last a few seconds during the treatment process.

How much is the treatment or what is the cost to have the Dermatofibroma treated and removed? Prices will vary across the UK and the world. In 2024 Skin Revision ( a Skin Clinic in Beaconsfield, Bucks UK ) were charging around £125 for the non-surgical treatment. Prices can vary depending on the size. Smaller lesions are often a little cheaper.

Conclusion

Dermatofibromas are harmless, benign skin growths that typically do not require treatment. However, if you find them uncomfortable or unsightly, there are effective options for reducing or removing them. At Skin Revision, the non-invasive CryoPen cryotherapy treatment is used to target and remove Dermatofibromas safely and effectively.
