KELOID



Keloid behind the ear lobe due to piercing Keloid on the chest




How are keloids formed ?
Normally when there is a wound on the skin due to trauma or infection, it heals with scarring. If the scar tissue continues to grow beyond the margins of the original wound, it forms a keloid.

What is a keloid ?
A keloid is a firm to hard, irregularly shaped, thickened overgrowth with claw like projections. It may be asymptomatic or painful, tender and pruritic (itchy).

Is there a known cause ?
It occurs only in people who are predisposed to it, i.e. have a tendency to form keloids.
Triggering factors are:
  • Trauma which may be due to a needle prick, vaccination, cut with a knife, insect bite etc.
  • Infections like furuncle, abscess, cystic acne etc.
  • Burns and scalds.

How can keloids be treated ?
In the past, modalities like surgical excision and primary suturing, excision and skin grafting have been tried but almost always the keloid recurred.
Cryosurgery with liquid nitrogen followed by intralesional therapy with a combination of steroid & 5 flurouracil has been found to produce very good results. It arrests the growth of the keloid and flattens it. A tailored silastic gel sheet along with a pressure garment has shown to augment the benefits of the above treatment.
The number of sessions of cryotherapy is determined by the thickness of the lesion and the response to the treatment.
Laser ablation with a Co2 Laser or radiosurgery is an alternative to cryotherapy.It could be combined with interferon injections,silastic gel sheet& pressure garment to achieve better results.
Multiple treatments with pulse dye laser is a fast emerging modality of treatment with promising results.

What are the advantages of cryotherapy for keloid ?
  1. It is an office procedure and hospitalization is not required.
  2. Multiple lesions can be treated at the same time.

What are the problems that one comes across in cryotherapy for keloid ?
  • More than one cycle is required depending on the thickness of the lesion.
  • A regular and long term follow up with the treating dermatosurgeon is mandatory for the best result.
  • There may be permanent hypo-pigmentation or depigmentation.
