Dermatofibroma
A dermatofibroma is a common benign skin growth that typically appears as a small, firm bump on the skin. Dermatofibromas often develop on the arms or legs but can occur anywhere on the body. They are usually brownish or reddish in color and may feel like a hard nodule under the skin.
The exact cause of dermatofibromas is not fully understood, but they are thought to develop in response to minor trauma or injury to the skin, such as insect bites, scratches, or shaving. Dermatofibromas consist of fibrous tissue and collagen and are typically harmless. They are more common in adults and may persist for years without causing any symptoms.
While dermatofibromas are usually benign, they can sometimes be confused with other skin conditions, such as melanoma or other types of skin cancer. It’s essential to have any new or changing skin growths evaluated by a healthcare professional, such as a dermatologist, for proper diagnosis and management.
In most cases, dermatofibromas do not require treatment unless they cause symptoms such as itching, pain, or irritation. If necessary, dermatofibromas can be removed surgically for cosmetic reasons or if they are causing discomfort. However, removal is not typically necessary unless the diagnosis is uncertain or the lesion is bothersome to the individual.
