Removal of seborrhoeic keratoses (which used to be called ‘senile warts’)
Seborrhoeic keratoses are benign spots on the skin that usually appear from the age of 40. They can cause itching. Seborrhoeic keratoses may be removed by freezing (cryotherapy) or scraping/curettage (excochleation).
Cryotherapy is a treatment in which the seborrhoeic keratoses are frozen. By freezing, the abnormal skin dies off and will subsequently be replaced by healthy skin. After treatment, there will be a scab on the skin that needs to heal. This takes about 1 to 2 weeks. The underlying skin has often a light or pink colour. This is new, healthy skin that will slowly obtain a normal skin tone. This ‘new’ skin must be protected from the sun for four weeks.
Excochleation is a treatment in which the seborrhoeic keratosis scraped off using a sharp knife or spoon-like instrument. As this is superficial treatment, the risk of scars is low.
