Hypertrophic vs Keloid the classification is mainly academic. Keloids expand beyond the wound. Hypertrophic can go away with time where Keloids are permanent unless treated.
Keloid:
Pink to purple and shiny
Extends beyond the boundary of the wound
Rounded
Can be painful
Hypertrophic:
Red to pink, can also be hypopigmented – without pigment.
Does not extend beyond the wound.
Get’s better with time
Nodular or non uniform structure
See how they can be confused and hard to classify, often a derm is needed with a trained eye to look at the wound super close.
They can reoccur in many patient types even with treatment as the body makes excess tissue in these people.
Goto a Dr with Skill treating them (ask how many have you treated, and B&A pics, also treatment methods).
