What is hypertrophic scar

First of all, hypertrophic scar, mostly in the depth of injury and only dermal trauma. The pathological difference between hypertrophic scar and normal scar only lies in the thickening of collagen fibers in the deep part of the scar, which is characterized by irregular arrangement, wave shape or rope shape. Hypertrophic scars often occur after deep burn wound healing. Reticular proliferative scars were also found in the sutures around the skin graft after skin grafting.

Secondly, the most common is any incision after suture scar also belongs to this kind. Hypertrophic scar showed prominent surface, irregular shape, uneven, flush and congestion, solid and tough. There is burning pain and itching.

Finally, hypertrophic scar has its own characteristics, mainly in the early stage of local redness and congestion, its tissue structure is the surface layer is covered by a layer of atrophic epithelial cells, the middle layer is vasodilation, and inflammatory cell infiltration, the bottom layer is less collagen fiber and a large number of connective tissue hyperplasia.
