Hypertrophic scarhttps://en.wikipedia.org/wiki/Hypertrophic_scar
Hypertrophic scar is a cutaneous condition characterized by deposits of excessive amounts of collagen which gives rise to a raised scar. But, the degree is less severe than that observed with keloids. Like keloids, they form most often at the sites of pimples, body piercings, cuts and burns. Mechanical tension on a wound may be the leading cause for hypertrophic scar formation.

Hypertrophic scar are red and thick and may be itchy or painful. The hypertrophic lesion do not extend beyond the boundary of the original wound, but may continue to thicken for up to six months. Hypertrophic scar usually improve over one or two years, but may cause distress due to their appearance or the intensity of the itching. They can also restrict movement if they are located close to a joint.

Ongoing hypertrophic lesions may be treated with corticosteroids injections.

○ Treatment
Hypertrophic scars can improve with 5 to 10 intralesional steroid injections 1 month interval.
#Triamcinolone intralesional injection

Laser treatment may be tried for erythema associated with scarring, but triamcinilone injections can also improve the erythema by flattening the scar.
#Dye laser (e.g. V-beam)

    Hypertrophic scarring represents an undesirable variant in the wound healing process. Another variant of wound healing, the keloid scar, is often used interchangeably with hypertrophic scarring, but this is incorrect. The excess connective tissue deposited in hypertrophic scarring is restricted to the area within the original wound. The excess connective tissue deposited in the keloid, however, extends beyond the area of the original wound.

    Scars are a natural and normal part of healing following an injury to the integumentary system. Ideally, scars should be flat, narrow, and color-matched. Several factors can contribute to poor wound healing. These include but are not limited to infection, poor blood flow, ischemia, and trauma. Proliferative, hyperpigmented, or contracted scars can cause serious problems with both function and emotional well-being.
