Thanks for the question. Seborrhoeic keratosis is a benign growth and it usually appears with age.
Seborrhoeic keratosis can be removed by electrosurgical ablation. A local anaesthetic injection is given before the procedure to minimize the pain. For smaller lesions, a numbing cream may be applied before the procedure.
After the lesion is ablated or burnt off, there will be some crusting over the area and the wound may take 1 to 2 weeks to heal. There may be some redness or pigmentation after the wound has healed but this will fade within a 1 to 2 months. The wound generally heals well.
Ablative lasers can also used to ablate the lesion and the outcome is similar to electrosurgical ablation.
Cryotherapy or treatment with liquid nitrogen is also an option. The lesion may develop a blister or scab after the treatment and will 'drop off ' together with the scab. However, the treatment may need to repeated if the lesion still persists after the 1st treatment.
