How does it look like ?
They are voluminous, sometimes painful and can itch. The specificity of these scars is that they extend well beyond the initial incision area.
Zones and risk factors ?
Their localization are common in the face, the neck, the ears, the shoulders, the thorax, and the anatomical areas where the skin is thick.
Patients with a dark skin phototype are particularly at risk. A genetic anomaly could also be at the origin of these complications.
When does it come to light ?
They appear later than hypertrophic scars up to one year after the onset of the initial lesion and they do not regress spontaneously. They often are resistant to treatments, even to surgical removals and may reappear again after.
What to do ?
In case of keloid history, a strategy of prevention is recommended (pressure therapy, injection of corticosteroids in the scar, compressive dressings, silicones, lasers etc.).
It may even question the risk and benefits of an aesthetic surgery.
