Patient after surgical excision was developed this scar What do you think the diagnosis?

-Patient after surgical excision was developed this scar What do you think the diagnosis?

It is a keloid(cuz it’s beyond wound line and is itchy)

-What is a keloid?is a type of scar beyond the site of wound. It is a

result of an overgrowth of granulation tissue (collagen type 3) at the site of a healed skin injury which is then slowly replaced by collagen type 1

• What is the difference between keloid and hypertrophic scar?

• Hypertrophic scar: After the skin is injured, the healing process usually leaves a flat scar. Sometimes the scar is hypertrophic, or thickened, but confined to the margin of the wound

-Keloid: Keloids, by contrast, may start some time after the injury and extend beyond the wound site.

What is the sign and symptoms of keloid?-raised and look shiny and dome-shaped-tend to be itchy, tender, or even painful to the

touch.-ranging in color from pink to red.- causing potential cosmetic problems,

• What is the cause?• Doctors do not understand exactly why keloids

form in certain people or situations and not in others. Changes in the cellular signals that control growth and proliferation may be related to the process of keloid formation,

• Location? can develop in any place that an abrasion has

occurred, insect bites, scratching, burns, or other skin trauma.

• Which people are most susceptible to keloids?

• -Keloids are equally common in women and men, although at least in times past more women developed them because of a greater degree of earlobe and body piercing among women.

• -In some cases, the tendency to form keloids seems to run in families.

• Treatment:-silicone sheeting.-Surgery-Dressings — Moistened wound coverings made of

silicone gel-Steroid injections — Steroid injections are best used as

the scar begins to thicken or if the person is a known keloid former.

Compression — Compression bandages applied to the site over several months,

-Cryosurgery -Radiation therapy-Laser therapy
