Types of Pigmentation – Moles

Pigmentation

A mole is described as an abnormal pigmentation of cells within the skin, although similar to age spots they must be considered differently. The cells are usually referred to as melanocytes. Many people do have moles at birth but most moles develop into adulthood. Moles result from the  proliferation of some pigmentation within the deeper layer of the skin. The moles which develop at birth are referred to as  congenital melanonaevi, and some of these  moles, like age spots develop as a result of the exposure of the skin to sunlight , while others develop spontaneously.  The most exposed area of the skin often develop Moles more than the rest.

One of the main areas of concern of the development of moles on the skin is that fact that some of them may go on and develop into Malignant melanoma- a form of skin cancer which might become fatal and can be treated best by surgical  excision.  Naturally, it is believed that moles may not pose a potential health hazards on the skin, however a count of 25 moles on the skin may predispose an individual to melanoma.  An individual with a serious linage of Moles in his or her family should be careful of some form of changing moles, while every susceptible individual is often advised to keep away from excessive sunlight exposure.

There are some signs and symptoms of malignancy which results from moles formation on the body; The moles may become itchy and painful, they may become more prominent and increase in size and irregular appearance. These irregular appearance often occur at the edges of the moles. The moles may also become darker in colour and becomes mottled, there might also be some formation of satellite pigmentation lesions.  Some moles formation may result in spontaneous bleeding which might result in more painful experience for an individual.

The changes in the size, shape and pigmentation of some moles will definitely indicate that it has become malign in nature.  It is ideal to examine any mole that looks unusual, though many of these moles cannot lead the cancerous skin disorders , however it will be very critical to do proper diagnosis to ascertain if such moles cannot lead to cancer.  A preliminary assessment of likely risk can be detected by your doctor asking for your family history as well as examine any changes to the shape, size and colour of the moles. Excision Biopsy is often the last resort in confirming if your moles are malign and pose a possible skin cancer treat.
