Brief summary
Keloid scarring is a severe cosmetic and painful disease of the skin. The gold standard
treatment is yet to be clarified. This randomized clinical pilot study will compare the
effects of two local treatments for preventing keloid recurrence after surgical removal;
steroid and verapamil.

Study hypothesis: Intralesional therapy with the calcium antagonist verapamil has equal
treatment efficacy as steroid injection.
