What is it?
The keloid is a proliferative lesion, formed by fibrous scar tissue, secondary to skin trauma. There is an individual predisposition for its appearance, being more common in people of African ascent.
The acne of the trunk can lead to keloid lesions (keloid acne) and also a type of folliculitis occurring in the neck (keloid folliculitis).
Characteristics and symptoms
The keloid is a tumor with a smooth surface and hard consistency. At first, its color is usually pink or red, evolving, later, to normal or darkened skin color. The anterior chest and shoulders are frequent location of keloids.
It differs from hypertrophic scars, in which scar tissue is not increased beyond the location of the trauma and tends to reduce over time.
In the photos below, it is noticed that the keloid has changed and increased in size but color became less reddish and more similar to normal skin.
Even minor trauma, such as an ear hole (photo below), may lead to keloids.
The treatment of keloid is sometimes difficult and often they relapse. The surgical removal should always be accompanied by other treatments, such as infiltration of corticosteroids, compression or radiation. Cryotherapy with liquid nitrogen prior to infiltration, sometimes can help achieving better results.
The combination of treatment techniques increase the chance of cure and should be determined according to each case.
