Melanocytic nevi or moles are benign tumors formed by a sum of cells named nevus cells. These cells are related to melanin cells, that is, the cells that produce melanin.

Melanocytic nevi are so frequent that are found practically on every human being. 1% of newborns have melanocytic moles. Their frequency and number increase as age increases while they reach their peak during puberty. Their size also grows and their color becomes darker until puberty and during puberty. Moles can occur anywhere on the human body but are more common in body parts exposed to sunlight. So, moles on the buttocks and female breasts are rarely met.

Moles are divided into those that are evident from birth called congenital and those that occur later named acquired.

Congenital moles measure from a few millimeters to several centimeters and may reach the point of covering a large proportion\of the limps or trunk. They may have hair on their surface while their color is usually brown. In extensive cases, such as the previous, there is an increased risk of developing a melanoma even during childhood. Therefore, the possibility of removing moles and covering the void with skin grafts should be considered.


Multiple warts may occur during pregnancy, especially in its second half. Most often they appear on the face, sides of neck, armpits and under breasts. The histological picture of these pregnancy warts is, when examined under the microscope with a special process and XROSI, the same as the one of common warts. Although they are usually small, they can reach sizes up to 5mm. Their development seems to be caused by hormonal disorders during pregnancy, as in most cases they disappear a few months after giving birth. And these warts are in no way cause for concern.


Warts are not malignant tumors. They are always confined on skin and there is no risk of becoming cancer if injured or removed. The only inconvenience is that they get tangled with jewelry and collars of clothes and might bleed or clot. In the latter case they become hard and black and after a few days fall on their own. Warts are usually disturbing for women who like to stress their neck and chest with jewelry or clothing. This happens because warts reveal one’s age –we should not forget that they usually appear in middle-aged people- while when darker than the skin, they become more visible and seem as if “smearing” the skin especially when visible from a distance. On men warts are tangled in collars or chains they might wear. These small problems constitute usually the causes that lead people with warts to a doctor asking for their removal.


Wart treatment is actually a removal or destruction of warts. The former is done with a mild local anesthesia; then a cut is made with a small scalpel or surgical scissors; what follows is electrocautery of the stem base from where it hangs. A skin excisional biopsy is not necessary. Their destruction is done by liquid nitrogen or laser. All these methods are equally effective and the final choice is made based on the patient’s and dermatologist’s preferences and on cost saving for the patient, as well as on the NHS.

Warts are very common; occur on middle-aged people; do not constitute a health problem; they are only an aesthetic disturbance; their treatment is easy with a mild discomfort and no other side effects.
