Dermatofibromas: What You Need to Know
At Aspen Dermatology, we are dedicated to providing high-quality care for all your dermatological needs. One common condition we treat is dermatofibromas, which are typically benign skin growths. Though they are generally harmless, understanding their causes, symptoms, and treatment options can help you maintain your skin health.
What is a Dermatofibroma?
A dermatofibroma is a non-cancerous, raised skin growth that usually appears on the arms, legs, or upper body. These growths are made up of fibrous tissue and may range in color from brown to pink, often resembling a small mole. Dermatofibromas are more common in adults, particularly women, and usually occur in people aged 20 to 40.
Symptoms of Dermatofibromas
Dermatofibromas are generally not painful, but some people may experience mild itching or tenderness around the growth. Key characteristics include:
- Size and Shape: Dermatofibromas are typically small, around 1-2 cm in diameter, and have a round or oval shape.
- Color: They can appear brown, pink, red, or purple.
- Texture: These growths are firm to the touch and may feel like a small, raised bump on the skin.
- Location: They most commonly develop on the legs, arms, or torso.
While dermatofibromas are usually not a cause for concern, any significant changes in their appearance or the development of new growths should be evaluated by a dermatologist.
Causes of Dermatofibromas
The exact cause of dermatofibromas is unknown, but they are thought to form as a result of trauma or injury to the skin, such as a bug bite, abrasion, or cut. This triggers the body’s wound healing process, leading to the growth of fibrous tissue. Genetics may also play a role in some cases.
Diagnosis
Diagnosing a dermatofibroma is typically straightforward. During an office visit, a dermatologist will examine the growth and may ask about your medical history and any potential skin injuries. In some cases, a skin biopsy may be performed to confirm the diagnosis and rule out other conditions.
Treatment Options for Dermatofibromas
In most cases, dermatofibromas do not require treatment unless they are causing discomfort or cosmetic concerns. If removal is necessary, treatment options include:
- Excision: The most common and effective way to remove a dermatofibroma is through a minor surgical procedure. Your dermatologist will make a small incision and remove the growth.
- Corticosteroid Injections: For smaller or flatter dermatofibromas, corticosteroid injections may help reduce inflammation and flatten the growth.
- Cryotherapy: Freezing the dermatofibroma with liquid nitrogen may shrink it or cause it to fall off, though it may not always be as effective as excision.
At Aspen Dermatology, our team of experienced dermatologists will work with you to determine the best course of treatment based on the size, location, and symptoms of your dermatofibroma.
Should I Be Concerned?
While dermatofibromas are generally benign, it’s important to monitor your skin and keep an eye out for any changes. If you notice any of the following, contact us immediately:
- Rapid growth of the dermatofibroma.
- Bleeding or ulceration.
- Change in color or shape.
- Pain or discomfort that doesn’t resolve.
These signs may indicate that the growth is something more serious and requires further evaluation.
