A dermatofibroma is a common, harmless skin growth.
What is a Dermatofibroma?
A dermatofibroma, also known as a fibrous histiocytoma, is a benign (noncancerous) skin tumor. It's characterized by a firm, subcutaneous nodule, usually less than 1 centimeter in diameter. These nodules are frequently found on the extremities (arms and legs) and affect people of all ages. While the exact cause is unknown, they are more common in women. Dermatofibromas are typically harmless and do not require treatment unless they are symptomatic or cause cosmetic concern.
Several sources describe dermatofibromas as:
- Benign fibrous nodules: They are overgrowths of fibrous tissue in the dermis (the deeper layer of skin). [Source: DermNetNZ, Bad.org.uk]
- Common cutaneous lesions: They are frequently found on the skin. [Source: Medscape, MedicalNewsToday]
- Small, firm bumps: Often resembling moles in appearance. [Source: Cleveland Clinic]
- Usually less than 1 cm in diameter: This is a characteristic size for these growths. [Source: ScienceDirect, Original Reference]
Examples of Dermatofibroma Descriptions:
- A small, firm bump on the leg: This might be a dermatofibroma.
- A nodule less than 1cm on the arm: Could be a dermatofibroma.
- A harmless skin growth: This is a common characteristic of a dermatofibroma.
Although dermatofibromas are typically harmless, it's crucial to consult a dermatologist for proper diagnosis and to rule out other potential skin conditions. Sometimes, they may be associated with other skin lesions, such as sweat duct cysts. [Source: ScienceDirect]
