Treatment of Keloids

For what conditions are cortisone injections used?

Cortisone injections can be used to treat the inflammation of small areas of the body (local injections), or they can be used to treat inflammation that is widespread throughout the body (systemic injections).

What is a keloid?

Keloids can be considered to be "scars that don't know when to stop." A keloid, sometimes referred to as a keloid scar, is a tough heaped-up scar that rises quite abruptly above the rest of the skin. It usually has a smooth top and a pink or purple color. Keloids are irregularly shaped and tend to enlarge progressively. Unlike scars, keloids do not regress over time.

What is the cause of keloids?

Doctors do not understand exactly why keloids form. Alterations in the cellular signals that control proliferation and inflammation may be related to the process of keloid formation, but these changes have not yet been characterized sufficiently to explain this defect in wound healing.

What are keloid risk factors?

Individuals with darkly pigmented skin are 15 times more likely to develop keloids, with those of African, Hispanic, and Asian ethnicities at greatest risk. Keloids are equally common in women and men. Keloids are less common in children and the elderly. Although people with darker skin are more likely to develop them, keloids can occur in people of all skin types. In some cases, the tendency to form keloids seems to run in families. Genetic studies have not as yet delineated the exact genes responsible for this predisposition.

In which area of the body are keloids most likely to appear?

Keloids develop most often on the chest, back, shoulders, and earlobes. They seldom develop on the face (with the exception of the jawline).
