Alibert 1816.

Bead scar, scar growth, scar keloid.

Benign, hypertrophic connective tissue proliferation.

Especially young adults.

Increased risk for Africans (compared to Caucasians up to 20-fold higher incidence) and Asians.

After trauma or spontaneously.

Increased collagen synthesis (structural proteins are mainly replaced by collagen type I).

Especially in the face, pre-sternal, and on the upper arms exophytic wash-like, hypertrophic, skin-colored to "ivory-like", roughly palpable, sharply defined, plate- or knot-like bulges with often telangiectasia. Loss of hair, sebaceous glands and skin relief. Unlike a hypertrophic scar, the keloid goes beyond its original boundaries.

  • Kenacort-A® 10 or 40 mg injection suspension
  • Clobetasol (Dermovate® Cream/Ointment) occlusive
  • Compression therapy
  • Cryosurgery: 2 x 15 seconds, goal is the tissue sinking of the keloid and healing ad secundam
  • Laser
  • Surgical removal: high risk of recurrence, possibly combined with brachytherapy and compression
