For the past 6-7 yrs my husband has had this bump on his mid back area. It is about quarter size and you can tell it is there when he wears t-shirts. I have been trying to get him to see a dermatologists to see what it is but he is one of those men that doesn't think he needs a dr. It never hurts him and sometimes it looks white sometimes it looks. It isn't a zit that is for sure. It is deep kind of like a cyst. Can this be anything else other than a cyst?
