Papular/Linear Keloids of White Skin.
These keloid often develop at a younger age, often in teenagers and among Asians or Caucasians. These keloids are often triggered by acne. Most these patients have other keloid lesions elsewhere on their skin. Some of these patients suffer from mild form of the disorder, and over time develop only few keloid papules, or nodules, on their face as well as their chest, shoulders or upper arms. Some others have more severe form of the disorder and develop numerous skin lesions over time.
Although the genetics of keloid disorder remains unknown, it is quite plausible to hypothesize that the genetics of the disorder is quite variable among different ethnic groups, and always more severe among Africans/African Americans and those with black skin.
