The histological scoring system consists of two categories: capsule and surrounding tissue [30].

Parameter	Score
		4	3	2	1
Capsule localization		Capsule on two sides present	Capsule on one (lower) side present	Capsule on one (upper/dermis) side present	No capsule present
Capsule formation		Dense	Loose fibroadipose or loose adipose	Loose fibroelastic	No capsule present
Capsule cellular features	Fibroblast thickness	More than 30 layers	10–30 layers	0–10 layers	0 layer
	Fibroblast contacting surface			No	Yes
	Acute/chronic inflammatory process			Chronic	Acute
	The severity of the inflammatory process	Severe	Moderate	Mild	None
Inflammatory cell location	Inflammatory cells location	End and middle	Middle	End	None
	Macrophages contacting surface			No	Yes
