SKIN CONDITIONS
Dermatofibroma
A benign, scar-like lump that can follow an injury, insect bite or minor skin damage, though the cause is often unknown.
- Common, non-cancerous skin growth
- Usually raised and firm
- Can appear anywhere but most common on the legs
- Treatment is not usually required
What does a dermatofibroma look like?
Dermatofibromas are usually small, ranging from 0.5 to 1.5 cm in diameter. They appear as firm, raised nodules that are either skin-coloured or may have a brownish colour. When pinched, the skin over a dermatofibroma may pucker. This is known as the “dimple sign”. Most commonly, they are pale in the middle and pigmented around the edge, although in people with darker skin types they are often pigmented throughout.

When is treatment needed?
A confirmed dermatofibroma is benign and can usually be left alone. Removal may be considered if it is uncomfortable, repeatedly irritated or bothers you.
At Spot Check Clinic, removal is by surgical excision. This leaves a scar, which may be more noticeable than the original lump. Your doctor will discuss that trade-off before you decide.
Arrange an assessment
A skin surgery assessment covers diagnosis, whether removal is appropriate, healing and the likely scar. A new or changing lump should be examined rather than assumed to be a dermatofibroma.
Considering dermatofibroma removal?
Discuss diagnosis, surgical removal and the likely scar with a doctor.
