Unlabelled: A surgical team from Interplast-Germany removed 387 keloids in 302 patients during 4 visits to Goma, Democratic Republic of the Congo, from 2015-2018. Preoperative and postoperative photographs and a thorough anamnesis of keloids were done for all patients. In addition, 18 selected biopsies from 4 types of keloids were histologically examined in Germany.

Methods: Treatment options were tested and keloid recurrence rates were compared with data from questionnaires, photographs, and histology.

Results: Keloids were classified accordingly as follows: (1) fresh nodular (continuously growing) keloids had a 30% recurrence rate after surgery: no common adjuvant therapy but triamcinolone acetonide (TAC) injections on onset, only; (a) earlobe keloids had the lowest recurrence rate after complete excision with negative resection margins; (2) superficial spreading (or butterfly) keloids were treated with TAC injections only; (3) mature (nongrowing or burned-out) keloids had also a low recurrence rate of 4.5%, which were then treated with TAC on onset, only; and (4) multiple keloids comprise various types in different stages.

Conclusions: According to this classification, about 50% of keloids may be removed surgically without risk of recurrence in the examined patient population in Africa, where only TAC injections, but no radiation, are available. Adjuvant TAC or radiation should be started at the onset of recurrence and not generally.
