Résumé
Some keloids show cystic cavities that give rise to acute inflammatory flares and oozing. These suppurative keloids (SK) have rarely been systematically studied. We conducted a retrospective cohort study to evaluate SK frequency and its risk factors. We also reviewed microbiological analyses as well as the histological features of removed SKs. Between July 1, 2015, and September 30, 2016, all adult patients attending a specialized keloid clinic were asked to participate. Clinical information and microbiological results were extracted from each patient's file. Histological features were observed and interpreted. In this study, we observed an SK rate of 26% for a mean keloid history of 17.2 years. Male gender, African ancestry, and a family history of keloids were significantly associated with suppuration. Microbiological examination revealed commensal skin flora 7/9 (77.8%), Staphylococcus aureus 1/9 (11.1%), and Enterococcus faecalis 1/9 (11.1%). Suppuration is a common complication of keloids occurring in patients with severe keloid disease and may arise from pilosebaceous occlusion and aseptic inflammation.

BACKGROUND
Some keloids show cystic cavities that give rise to acute inflammatory flares and oozing. These suppurative keloids (SK) have rarely been systematically studied. We conducted a retrospective cohort study to evaluate SK frequency and its risk factors. We also reviewed microbiological analyses as well as the histological features of removed SKs.

RESULTS
In this study, we observed an SK rate of 26% for a mean keloid history of 17.2 years. Male gender, African ancestry, and a family history of keloids were significantly associated with suppuration. Microbiological examination revealed commensal skin flora 7/9 (77.8%), Staphylococcus aureus 1/9 (11.1%), and Enterococcus faecalis 1/9 (11.1%).
CONCLUSION
CONCLUSIONS
Suppuration is a common complication of keloids occurring in patients with severe keloid disease and may arise from pilosebaceous occlusion and aseptic inflammation.
