[Keloid of the external ear].

Keloid formation is an unpredictable complication to normal scar tissue development. The etiology is unknown, although an individual predisposition may be present. There is a regional propensity for the head, neck and upper torso. The treatment is difficult, and this should be taken into consideration when cosmetic procedures are being contemplated. This type of surgery should be avoided in individuals with previous keloid formation. Four cases of keloid formation, two after ear lobe piercing and two after otoplasty are presented and a satisfying outcome of surgical revision with ensuing steroid medication is reported.
