In this post we shall discuss about Keloid formation and treatment
Keloid is a defect in maturation and stabilization of collagen fibrils as normal collagen bundles are absent
It is common in females
Mostly seen in black people
Genetically predisposed and very rare in Caucasians
Keloid grows even after 6 months. It extends into adjacent normal skin. It is brownish black/pinkish black in color, painful, itchy and hyperaesthetic.
Keloids can be associated ot Ehlers Danlos Syndrome or Scleroderma
Spontaneous keloid is formed when an unnoticed trauma heals without scar formation.
Some keloids don’t grow after an initial growth
Keloid contains proliferating immature blood vessels and type III thick collagen stroma and immature fibroblasts.
Keloids are common over sternum along with upper arm, chest wall, front of lower neck

Treatment
Excision and skin grafting can be done
Vit. E/ palm oil massage
Intrakeloidal triamcinolone injection once in 7-10 days followed by excision. The usual sequence is Steroid injection – Excision – Steroid Injection
Methotrexate and Vit. A
Compression dressings with silicone gel sheets
Laser therapy
Intra lesional excision retaining the scar margin could prevent recurrence. It is preferred over only excision.
