Benign tumours
Nevus (raised moles)
Dermal melanocytic nevi are benign lesions that appear during the first years of life and acquire volume and colour changes over the years. For diagnosis, assessment by a dermatologist is essential and dermoscopic evaluation is often required, especially to rule out malignancy.

Not all melanocytic nevi are treated in the same way, and this will depend on the subtype (dermal, compound, etc.), the location and the characteristics of the patient. In the case of dermal nevi, the treatment of choice is laser removal, although surgical or electrosurgical treatment may be considered in selected cases. The CO2 laser is the most commonly used for this procedure.
It can be an uncomfortable procedure so local anaesthesia is usually used on the area to be treated just prior to treatment.
Dermal nevi are usually completely removed with the CO2 laser (provided the diagnosis is correct). There is a small risk of recurrence, especially in more immature lesions, which can be re-treated at a later stage.
After CO2 laser nevus removal, a crust may appear, which may take about a week to fall off. It is usually necessary to use repair creams or silicone gel creams, as well as correct daily hygiene and strict photoprotection.
