i have noticed recently for the first time ever in my life , some four or five small rounded light colored spots on my elbow and its my first time to encounter such thing , and i dont remember that i used to lean my elbow on hard desks or surfaces , so where do such light white spots came from i really cant fugure out the reason for the out coming of such spots , what should i do and how can i get rid of it , it looks like a skin disease not pleasant to see , can i get any help here ? what is the solution for this ?

thanks :-(
