-Définition
Une cicatrice chéloïde est le résultat d’un processus cicatriciel bien spécifique au niveau du derme.
Alors qu’une cicatrice reste relativement plane en temps normal, la cicatrice chéloïde se développe
en relief. Au début, on constate le développement d’une petite boule dure de coloration brun-rouge.
Ce nodule se développe, s’épaissit et s’élargit. La cicatrice chéloïde peut s’étendre sur quelques
millimètres à plusieurs centimètres.
