As the congenital nevus or the facial mole also mimic other skin lesion, it is essential to do a differential diagnosis. Once the causes and diagnosis is confirmed, we then can decide what the best option for remove moles is, such as the laser removal, electrocautery, surgical or cryo.
Medical laser is used for removing flat mole a swell as the raised mole fairly efficiently. However, laser remove the mole by only cauterization, removing only the superficial skin. It may be causing minimum collateral heat damage to the surrounding tissue, and therefore no scar, but will need 2 to 3 treatment.
The mole tends to go deeper into the skin, unless one uses an aggressive laser treatment which may leave a scar may not be the option. The advantage is that it do not require stitching or suture as compared to do surgical excision.
This forms an alternative to the laser cautery. This uses the electric current to burn the moles. The current is set to a level such that it only reach the required layer of the outer skin and in so doing can avoid the possibility of scaring. A total of usually 1 to 3 sessions is required to completely remove a mole.
Here we use a freezing solution to freeze the mole first, then shave it off by a scalpel. The stump is then cauterized. A caution is that if suspected of a melanoma, there should be no freezing done as this causes a freezing artifact of the tissue sample and interfere with the histo-pathological interpretation. Instead a full surgical excisional biopsy should be done. The resulting elliptical skin deficit is sutured and approximated back.
