Nevus

yOz yOz! Guess wad im surfing now.. MOLES!! muahaha.. as some of u know.. i have quite a lot of moles.. especially at my arms.. haiz.. sick right!!! ugly seh.. Just now had lunch with Angela.. we happened to talk about moles also.. haha.. so i went to check it out..
Well, scientific term for mole is nevus (pronounced as knee-vus). It is caused by a cell called melanocyte. Melanocytes are supposed to be spread around, but instead, it clots up and hence a nevus is formed. Therefore, in actual, moles are just pigment-containing skin cell.
There are 3 types of nevi - Acquired Nevi, Atypical moles (dysplastic nevi) and Congenital Nevi. The most common type of mole is acquired nevi. It starts appearing during your teen age. A person normally has 15 - 20 moles around your body. It is relatively small. It is either in black or brown colour.
Next, Atypical moles. They are slightly bigger in size then acquired nevi. The colour varies and normally has a pink background.
Lastly, congenital nevi. Mainly covers a large area of body, some whole body. Large nevi can vary greatly in size, shape, color, surface texture, and hairiness. Some are reddish-tan; others are almost black. Most are shades of brown. Some have fine downy hair; many have long, thick, darker hair. Some have a permanent "goose bump" appearance. Their colour may stay the same, lighten slowly or darken slowly over time.
Isnt it scary??!! From a small more.. and become a giant one.. wahh.. moles also have a lot of knowledge behind it. Oyah.. giant moles also can lead to a higher chance of getting skin cancer. So must be careful. Wondering wads the treatment right.. Surgical excision should be done where cancer is a reasonable concern. Improving cosmetic appearance is another reason for excision, but all surgery leaves some scarring. Smaller nevi can be "shaved off". Larger ones can be cut out directly and the wound edges sewn together. Much larger nevi may be excised in stages by taking a little more out each time until the entire nevus is removed. This is called "serial excision." Cutting out very large nevi will leave behind a raw area that is too big to be sewn together and must be covered. This can be done with a split thickness skin graft from some other normal area of the body. The skin-grafted area will have varying degrees of scarring and will usually be thinner and more fragile than normal skin.
Okok.. nice sharing with u all my 'mole' discovery.. haha! hope u all learnt somethg new from here.. cya!
