Primary Outcome Measures:
  • Determine the prevalence different phenotypes of keloid in participants. [ Time Frame: Two years ] [ Designated as safety issue: No ]
    Prevalence of different phenotypes of keloid will be measured in the study population and reported. Prevalence of familial keloid in the study population will also be determined and reported. Data will be analyzed to determine the distribution of keloid among different ethic groups. Data will be analyzed to report the percentage of patients who have had one or more treatments and the percentage of patients who have had successful treatments.

Estimated Enrollment: 10000
