General Overview Of Intralesional Cryotherapy In Managing Keloids

Abstract

Background: Keloid is a dermal fibro-proliferative disorder that occurs due to abnormal wound healing and excessive
deposition of collagen. It presents as a raised scar which is sometimes confused with a more common type of scars
called hypertrophic scars. The incidence of keloids is highest among darker-pigmented persons of African, Asian and
Hispanic descent with an age range from 10-30 years old. Keloids are slightly more common in females, likely due to
more cosmetic procedures like ear piercing. Intralesional cryotherapy is a relatively new technique in the treatment of
skin lesions which freezes the lesion from the centre outwards. It has been proved to be a safe and effective modality,
with few adverse effects.
