Moles is a common disease it is also hyper-pigmentation problem of skin. A common example of hyper pigmentation is melasma in which dark spots appear on the cheeks and top of nose.



Hypo-pigmentation  

Hypo-pigmentation; a word depigmentation is also use in place of it. Depigmentatin occurs when the production of skin pigmentation substance reduced or stop. Normally such skin condition causes  white patches on skin.
In depigmentation the skin becomes lighter as compared to its surrounding.  Example of skin condition causes depigmentation are nevus depigmentosus (quite stable scars may appear any part of body), Pityriasis Alba (a common condition in children), Idiopathic guttate hypomelanosis, vitiligo and  white scars due to injuries.
