Abnormal scarring in susceptible individuals.
More common in darker skin types.
Diagnosis is clinical.
Treatment results are very variable. First-line options include silicone gel, intralesional corticosteroids, and pressure therapy.
Surgery is reserved for patients who do not respond to medical therapy, and must be given with adjuvant pressure therapy, intralesional corticosteroids, or radiation therapy to prevent recurrence.
A keloid is an abnormal form of scarring (a fibroproliferative disorder); it is not associated with maturation, regression, or contraction.
