The main advantage of treating moles with a laser is that it avoids scarring. Removing moles with a scalpel regardless of size and number, always leads to scars.

By using a laser you get a better aesthetic opportunity. Because laser light is absorbed by the pigment in the nevus. Consequently Nevus heating occurs and this in turn leads to vaporization and nevus removal without damaging neighboring tissue.

The Helios II Laser treatment is the most accurate to date for this treatment.
Patient satisfaction is high.

Recurrences are well accepted and easy to correct. Therefore, the lasers generate more efficient results when trying to remove moles due to aesthetic reasons.

After 20 years of using various laser technologies, I found that the HELIOS II frequency doubled Q-switched Nd:YAG Laser with Q-switch 1064nm , free running 1064nm and Q-switched 532 nm modes is the ideal tool to remove moles and Nevus of Ota quickly and safely Leaves no scars and gives very satisfactory aesthetic results.

Nevus are benign skin lesions in their vast majority, however prior to any laser treatment, one must perform a clinical evaluation, anatomopathologic and Videoscopic. The majority of moles can be removed with laser in a single session and the patient can continue with their normal life immediately, without carrying any occlusive dressing.

Most moles are completely benign and do not have any risk of malignancy, but it must be surgically removed and sent for histo pathological study all nevi that:
• Has colors and irregular borders.
• Grows quickly.
• Bleeds.
• Frequently swells.
• It is located on a friction zone such as the base of the foot.
• Are very dark and found in hard to access áreas such as scalp, peri anal, etc.
• Big size Nevus.

Melanocytic nevus.
Melanocytic nevus are common benign skin lesions that are found in almost all of the population.
They might be flat or elevated , asymptomatic, with well defined edges, regular color and frequently small in diameter (<6 mm in diameter).

Initially, the nevus cells are located between the epidermis and the dermis ( dermal- epidermal junction ) and are called junctional nevus or Union. At that moment flat lesions are dark brown or black in color. As time passes, the groups of melanocytes ( teak ) proliferate and extend into the dermis , which are called compound melanocytic nevus. The color of melanocytic nevus varies with the location of the related pigment (melanin).
If the majority of pigmented cells are found in the epidermis ( skin surface area ) the will be brown color , while if it is located on the epidermis and superficial dermis will be black , or dark brown, and if nevus melanocytes ( nevus cells ) are located in the deep dermis , the lesion assumes a bluish color (blue nevus).

The number of melanocytic nevus that develops a person throughout his life is variable and is influenced by genetic and environmental factors (especially skin that has been exposed to sun).

The melanocytic nevus are dynamic blooms that change throughout life . They tend to darken with sun exposure or during pregnancy and in adulthood tend to gradually lose their pigmentation and may even disappear in old age.

Types of melanocytic nevus.
A) BIRTH melanocytic nevus.
They may be of varying size, ranging from a few millimeters up to large part of the body surface. They split in congenital melanocytic nevus which are empirically small , mid-size and giant . Described an increased risk of developing malignant melanoma especially in melanocytic nevus.

B) ACQUIRED melanocytic nevus.
These are lesions of size, color , variable number . They are well defined and regular in coloring. They may be flat or raised. They tend to be more abundant in areas exposed to the sun.

C ) ATYPICAL nevus.
Atypical nevus are moles with irregular borders , diffuse colored and/or large in size. These patients require periodic dermoscopic and clinical controls. Preventive surgery is paramount. Whenever possible these injuries should be removed surgically and sent to a dermatopathologist to perform a proper diagnosis.

Tips.
• Photoprotection.
• Self Exploration.
• Regular dermatological controls.
