Dermatofibromas, also known as benign fibrous histiocytomas, are common skin growths that can appear on various parts of the body. While these growths may raise concern for those unfamiliar with them, they are entirely benign and not a form of skin cancer. At MySkinDoc, we aim to empower patients with knowledge and provide guidance on managing dermatological conditions. In this article, we’ll explore what dermatofibromas are, what they look like, and the available treatment options.
What Is a Dermatofibroma?
A dermatofibroma is a small, firm, and benign growth that develops in the dermis, the thick layer of living tissue beneath the outermost layer of skin. These growths are made up of a mixture of fibroblasts (cells that produce connective tissue) and histiocytes (a type of immune cell). Dermatofibromas are often the result of minor skin injuries such as insect bites, folliculitis, or trauma, though the exact cause isn’t always identifiable.
They are most commonly found on the legs but can occur anywhere on the body. Dermatofibromas are more frequently seen in adults, particularly women, and
rarely appear in children.
What Do Dermatofibromas Look Like?
Dermatofibromas have distinct characteristics that make them relatively easy to identify:
Size and Shape: They are typically small, ranging from 0.5 cm to 1.5 cm in diameter, and have a rounded or oval shape.
Color: These growths often appear tan, brown, or reddish-brown. The coloration may vary slightly depending on an individual’s skin tone.
Texture: Dermatofibromas feel firm to the touch and may be slightly raised above the skin surface. Occasionally, they have a dimpled center that becomes more noticeable when the skin is pinched (“dimple sign”).
Symptoms: While dermatofibromas are usually painless, they can occasionally be tender, itchy, or sensitive, especially if irritated by clothing or shaving.
Is a Dermatofibroma Skin Cancer?
One of the most common concerns among patients is whether a dermatofibroma is cancerous. The reassuring answer is no – dermatofibromas are benign and pose no risk of becoming skin cancer. However, because they can sometimes resemble other skin conditions, including malignant ones, it’s essential to have any new or unusual skin growth evaluated by a healthcare professional. At MySkinDoc, our team can assess your skin via a remote or in-person consultation to provide an accurate diagnosis and peace of mind.
How Are Dermatofibromas Diagnosed?
Diagnosing a dermatofibroma typically involves a visual examination by a dermatologist. Some common methods include:
Clinical Examination: A dermatologist will inspect the growth, noting its size, shape, color, and texture. The “dimple sign” is a helpful diagnostic clue.
Dermatoscopy: This tool allows for magnified examination of the lesion’s structure, helping to differentiate it from other skin conditions.
Biopsy (if necessary): In rare cases, if there is any doubt about the diagnosis, a small sample of the tissue may be taken for microscopic examination. This is especially important for lesions that display unusual characteristics or rapid growth.
What Are the Treatment Options for Dermatofibromas?
In most cases, dermatofibromas do not require treatment, as they are benign and typically cause no significant symptoms. However, treatment may be considered for cosmetic reasons or if the growth causes discomfort. Options include:
Surgical Excision:
This is the most definitive treatment and involves removing the dermatofibroma along with its surrounding tissue.
Surgical removal may leave a scar, so this option is usually reserved for cases where the lesion is particularly bothersome.
Cryotherapy:
Cryotherapy involves freezing the lesion with liquid nitrogen. This method can reduce the size of the dermatofibroma but may not completely remove it.
Steroid Injections:
Corticosteroid injections can help flatten and soften the dermatofibroma, reducing its prominence. This is often used for symptomatic relief rather than complete removal.
Laser Therapy:
Certain types of lasers can improve the cosmetic appearance of dermatofibromas, particularly if discoloration is a concern. However, this treatment does not remove the lesion entirely.
Self-Care Tips for Managing Dermatofibromas
While dermatofibromas are harmless, there are steps you can take to prevent irritation or discomfort:
Avoid Irritants: Be cautious with clothing or shaving around the affected area to prevent irritation.
Moisturize: Keeping the skin hydrated may reduce any associated itchiness.
Monitor Changes: Regularly check the growth for any changes in size, shape, or color. While rare, any changes should be assessed by a dermatologist.
When to See a Dermatologist
Although dermatofibromas are benign, it’s crucial to consult a dermatologist if:
The lesion grows rapidly or changes in appearance.
You notice new symptoms such as pain, bleeding, or ulceration.
You are uncertain about the diagnosis or have concerns about the cosmetic impact of the growth.
At MySkinDoc, we offer professional assessments through remote consultations, allowing you to receive expert advice without leaving the comfort of your home.

However, it’s understandable that their appearance or associated symptoms may cause concern for some individuals.
