A dermatofibroma, also known as histiocytoma, is a common benign skin tumor. It occurs more frequently in adults, particularly women. Dermatofibromas can appear on any part of the body but are most commonly found on the legs, arms, and torso.
Symptoms
Dermatofibromas appear as small, firm, round bumps on or in the skin. Their color can range from pink to brown or purple. They are usually painless but can sometimes be tender or itchy. Pressing the bump typically causes it to dimple inward.
Causes
The exact cause of dermatofibromas is unknown. Some studies suggest they may develop following minor skin injuries, such as insect bites or pricks, but this is not definitively proven.
Diagnosis
Your doctor can usually diagnose a dermatofibroma by examining your skin. In some cases, your doctor may recommend an excision or skin biopsy to confirm the diagnosis and rule out other skin conditions.
Treatment
Treatment for dermatofibromas is usually not necessary since they are benign and harmless. However, if the bump is bothersome or causes cosmetic concerns, your doctor may suggest removing it surgically.
Self-Care Tips
While treatment is often unnecessary, you can alleviate any itchiness or tenderness by keeping the area clean and moisturized. Avoid scratching to prevent irritation.
