The three groups of samples were not consistent in morphology, representing the morphological changes of the disease from normal skin to inflammatory tissue, and finally forming keloids (A) H&E staining of group N. Magnification, ×100. (B) H&E staining of group I. Magnification, ×100. (C) H&E staining of group K. Magnification, ×100. The deep purple cells indicated by the red arrow are inflammatory cells.
