What is a hypertrophic scar?

A hypertrophic scar represents excessive collagen deposition at a site of wound healing. Typically, the scars are initially red, raised, firm, and often pruritic. With time, they flatten and become white. Hypertrophic scars do not extend beyond the limits of the original trauma. Scars, including hypertrophic scars, are not usually considered to be neoplasms because they are reactive and eventually regress with time.
