small skin lesions
There are many different small, benign skin lesions. Flat, pigmented lesions are usually treated by classical excision or radiofrequency electric current excision. This invariably produces a scar. Delicate suturing generally yields a linear scar, without stitch marks.
Some people have a lot of small skin lesions. From the aesthetic point of view, a lot of small scars may look even worse. When there is doubt about the medical necessity to remove a pigmented skin lesion, the most careful strategy is to consult a dermatologist (skin specialist). It may be a good policy to carefully follow up the moles and only operate on those that really have to be removed for medical reasons. If there are aesthetic considerations a plastic surgeon may be involved later on.
Many skin lesions are less dark and are raised above the level of the skin. Some can be removed by a shaving technique, in the best case without visible scarring. If there is a scar, it usually looks like a pale spot which is flat or slightly raised or depressed but still less noticeable than a linear scar after classic excision. These skin moles often occur in the face. They grow very slowly while becoming paler. Sometimes thick hairs appear on the surface. They are often considered to be a sign of ageing. Other, benign lesions are more commonly found on the trunk and the limbs. Shaving of these lesions, when necessary followed by permanent hair removal can be performed at the consultation. My favourite technique combines shaving for histological examination and treatment with the CO2 laser. For raised lesions that have a thin connection to the skin surface shaving with a 4 MHz radiofrequency current is an excellent treatment.
Some small skin lesions are the result of scar formation and/or infection. One of the treatment modalities is the abrasion (dermabrasion) of raised scars and/or remnants of grit encapsulated in the skin.
