Keloid is a form of scarring. It may appear on skin as red, raised formation of fibrous scar tissue, caused by excessive collagen formation in the skin layer (dermis) during the process of connective tissue repair, after any trauma or injury to skin.
Some people have a tendency to have keloid formation after any kind of skin injury.
Keloids results from skin injuries such as:
- Surgical cuts
- Scratch marks
- Vaccination sites
- Ear piercing
Signs and Symptoms:
Keloids look like:
- Dome shaped raised and shiny appearance.
- Pink to red in color
- Sometime pain or tenderness
- Clinical examination- The diagnosis is made by just looking at the lesion and enquiring about the history of skin injuries.
- Skin biopsy- It may be required to differentiate with other skin tumors.
Conventional treatment for Keloid:
- Surgical removal- It is more risky as it causes formation of recurrence of Keloid at the site of surgical incision.
- Laser treatment- It is more beneficial and safe. It is not very painful. It helps in regression of the Keloid by suppressing the proliferation of Keloid fibroblast.
- Corticosteroid injections- It is used as a first line of treatment where injection is given at the site of the Keloid. It helps in flattening the Keloid.
- Radiation- It is used after surgical removal of the Keloid. It is safe and effective and helps in reducing the recurrence of Keloids resulting from surgical excision.
- Cryotherapy- Liquid nitrogen is used to flatten the Keloid.
