Picture of Hypertrophic Scar
Hypertrophic scars and keloids are both characterized by excess fibrous tissue at a site of injury in the skin. Hypertrophic scars are confined to the original wound site, whereas keloids, by contrast, extend beyond the original wound site. Both are common and frequently disturb patients greatly, both as an unsightly scar as well as a reminder of previous trauma or surgery. Acne scars result from the loss of underlying collagen and elastic tissue from dermal inflammation associated with acne, particularly cystic acne. Acne scars are also very common and a source of distress to the patient, both for their obvious appearance on the face as well as a reminder of previous acne.
Shown here is a dermal injection of a hypertrophic scar that resulted from a shave biopsy.
