Zusammenfassung
Keloide bilden sich meist nach operativ oder traumatisch entstandenen Wunden. Sie
werden zusätzlich nach Tätowierungen, Piercings und in Folge lang anhaltender, entzündlicher
Erkrankungen der Haut beobachtet. Eine genetische Disposition wird diskutiert. Besonders
gefährdete Regionen sind die vordere Brustregion, die Schulterpartie und die Ohrläppchen.
Bei disponierten Personen können Keloide sogar spontan entstehen. Trotz vieler verschiedener
Therapiekonzepte und Studien zur Behandlung von Keloiden, gestaltet sich deren Therapie
aufgrund der hohen Rezidivrate nach wie vor schwierig. Neben etablierten Techniken
zur Vorbeugung und Behandlung von Keloiden werden heute neuere, weniger etablierte
Verfahren (Farbstofflaser, Imiquimod), zum Teil in Kombination, erfolgreich eingesetzt.
Abstract
Keloids may arise following any insult to the deep dermis or develop after minor injuries
and may even form spontaneously on the mid-chest in the absence of any known injury.
In the majority of cases, keloids develop in wounds at anatomic locations with high
tension, such as anterior chest, shoulders and earlobes. Multiple studies on keloid
formation have been conducted for decades and have led to a plethora of therapeutic
strategies in order to prevent or attenuate excessive scar formation. However, most
therapeutic approaches remain clinically unsatisfactory, mostly due to the high recurrence
rates of keloids. Besides well known therapeutic approaches, today, emerging treatment
strategies including pulsed dye laser and imiquimod crème extend the spectrum of keloid
therapy.
